+# Project Handoff
+
+This document summarizes the current state of the spreadsheet importer so it can be copied into a new project or used as a reference for the next stage.
+
+## What This App Does
+
+This is a plain PHP and Bootstrap web app that:
+
+- accepts an Excel upload
+- validates the workbook headers
+- ignores the `Revenue Type` column
+- normalizes and stores imported row data in PostgreSQL
+- calculates stage 1 derived fields during import
+- wipes previous imported data before each new import
+- shows a 20-row preview on the home page
+- provides a full DataTables page for the latest imported batch
+
+The app is structured so future import stages can add more rules without rewriting the UI or database layer.
+
+## Move Notes
+
+The codebase is largely relocatable because internal includes and asset URLs are built from the project root.
+
+Before moving the project into a new folder:
+
+- set `APP_URL` to the new base URL or folder path
+- keep `DATABASE_URL` or the values in `config.php` aligned with the target environment
+- rerun `composer install` if `vendor/` is not copied with the project
+- confirm the web server is still pointing at `public/` as the document root
+
+The only folder-sensitive setting in the app itself is the redirect base URL used after imports and clears.
+
+## Current Stack
+
+- PHP
+- Bootstrap 5
+- PostgreSQL
+- Composer for the spreadsheet library
+- OpenSpout for reading Excel files
+
+## Important Files
+
+- `config.php`
+  - Root config file for app name, URL, and PostgreSQL connection settings.
+  - This replaced `.env`-style configuration.
+
+- `bootstrap.php`
+  - Starts the session.
+  - Loads Composer's autoloader if present.
+  - Requires the app files manually.
+  - Exposes the `app_config()` helper for config lookup.
+
+- `index.php`
+  - Root entrypoint.
+  - Loads `public/index.php` so the app can be reached from the project root.
+
+- `public/index.php`
+  - Main web entrypoint.
+  - Creates the controller and renders a friendly setup error page if startup fails.
+
+- `public/assets/app.js`
+  - Handles file upload progress.
+  - Drives the chunked import loop with repeated `process-chunk` requests.
+  - Handles the clear-data button.
+  - Reloads the page after import or clear completes.
+
+- `public/assets/styles.css`
+  - Custom Bootstrap styling and layout.
+
+- `templates/index.php`
+  - Home page with upload form, status messages, and a 20-row preview table.
+
+- `templates/table.php`
+  - Full-table page for the latest imported batch.
+  - DataTables server-side search and paging.
+  - ColumnControl header buttons and header filters.
+
+- `templates/partials/navbar.php`
+  - Shared navigation between the preview and full-table pages.
+
+- `bin/migrate.php`
+  - Creates the PostgreSQL schema.
+
+- `app/Database.php`
+  - Builds the PDO connection from `config.php`.
+
+- `app/Http/AppController.php`
+  - Coordinates upload, clear, render, and JSON responses.
+
+- `app/Import/SpreadsheetReader.php`
+  - Streams workbook data with OpenSpout.
+  - Builds a temporary chunk cache from the uploaded file.
+  - Detects the real header row.
+  - Ignores `Revenue Type`.
+  - Normalizes cell values.
+
+- `app/Import/SpreadsheetRowProcessor.php`
+  - Applies all stage 1 calculated field rules.
+
+- `app/Import/ImportService.php`
+  - Orchestrates validation, clearing, processing, and storing.
+
+- `app/Import/ImportRepository.php`
+  - Handles PostgreSQL inserts, truncation, counting, and pagination.
+
+## Database Design
+
+The schema is intentionally flexible and uses JSONB for future growth.
+
+### `import_batches`
+
+Stores metadata for each import run:
+
+- source filename
+- original headers
+- calculated headers
+- row count
+- warning count
+- created timestamp
+
+### `import_rows`
+
+Stores each imported row:
+
+- batch id
+- source row number
+- original row data as JSONB
+- normalized row data as JSONB
+- calculated row data as JSONB
+- merged row data as JSONB
+
+The row-level JSONB storage makes it easier to add more calculated fields and import stages later without changing the schema every time.
+
+## Import Flow
+
+The current flow is:
+
+1. User uploads an Excel workbook.
+2. The app validates the file extension.
+3. The upload is stored in a temp file and an import token is returned.
+4. The workbook is streamed once into a temporary chunk cache.
+5. The browser repeatedly calls `action=process-chunk` with that token.
+6. Required columns are checked by header name.
+7. Existing imported data is wiped.
+8. A new batch record is created.
+9. Each cached row is normalized.
+10. Derived fields are calculated.
+11. The row is inserted into PostgreSQL.
+12. The home page reloads and shows a 20-row preview table.
+13. The full table page provides server-side search and pagination for the latest batch.
+
+## Validation Rules
+
+Required columns:
+
+- `Accrual Category`
+- `Local Selling Company (S/T)`
+- `Contracting Party`
+- `Rights Holder Liable Flag`
+- `Global Transfer Pricing Flag`
+- `Domestic/ Foreign Flag`
+- `Ownership Type`
+
+The app also:
+
+- handles blank and null values safely
+- preserves formatted text values from Excel
+- treats numeric-looking values consistently
+- shows readable import errors
+
+## Stage 1 Calculated Fields
+
+### 1. `Actual/Accrual`
+
+Rule:
+
+- If `Accrual Category` equals `##`, return `Actual`
+- Otherwise return `Accrual`
+
+### 2. `US/ex-US sale`
+
+Rule:
+
+- If `Local Selling Company (S/T)` is between `1700` and `1809` inclusive, return `US`
+- Otherwise return `ex-US`
+
+### 3. `Contracting Party Filtered`
+
+Rule:
+
+- If `Contracting Party` equals `1756`, return `1756`
+- If `Contracting Party` equals `1100`, return `1100`
+- If `Contracting Party` equals `1902`, return `1902`
+- Otherwise return `LOCAL`
+
+### 4. `String`
+
+Rule:
+
+Concatenate, in this exact order with no separator:
+
+- `Contracting Party Filtered`
+- `Rights Holder Liable Flag`
+- `Global Transfer Pricing Flag`
+- `Domestic/ Foreign Flag`
+- `Ownership Type`
+
+Example:
+
+- `1756YYFDI`
+
+### 5. `2110 Applicable X201`
+
+Rule:
+
+- If the `String` value is in the approved list, return `X`
+- Otherwise return blank
+
+### 6. `Class`
+
+Rules are applied top to bottom and the first match wins:
+
+- `A` if `Contracting Party = 1902`
+- `B` if `Contracting Party = 1756`, `Rights Holder Liable Flag = Y`, and `Local Selling Company (S/T)` is not between `1700` and `1808` inclusive
+- `C` if `Contracting Party = 1756`, `Local Selling Company (S/T)` is between `1700` and `1808` inclusive, and `2110 Applicable X201 = X`
+- `D` if `Contracting Party = 1756`, `Local Selling Company (S/T)` is between `1700` and `1808` inclusive, and `2110 Applicable X201` is not `X`
+- `E` if `Contracting Party = 1100` and `Local Selling Company (S/T)` is not between `1700` and `1808` inclusive
+- `F` if `Contracting Party = 1100` and `Local Selling Company (S/T)` is between `1700` and `1808` inclusive
+- `G` if `Contracting Party Filtered = LOCAL`
+- `H` if `Contracting Party = 1756`, `Rights Holder Liable Flag = N`, `Global Transfer Pricing Flag = Y`, and `Local Selling Company (S/T)` is not between `1700` and `1808` inclusive
+
+## UI
+
+The Bootstrap UI includes:
+
+- upload form
+- navbar for preview/full-table navigation
+- progress bar
+- success/error messages
+- imported row count
+- clear imported data button
+- 20-row data preview table
+- current batch summary
+- full table page with search and pagination
+
+The app uses relative asset paths so it works from either:
+
+- the project root, or
+- the `public/` directory
+
+## How To Set This Up In A New Project
+
+1. Copy these files/folders into the new project:
+   - `config.php`
+   - `bootstrap.php`
+   - `index.php`
+   - `bin/`
+   - `app/`
+   - `public/`
+   - `templates/`
+   - `composer.json`
+   - `composer.lock`
+
+2. Install dependencies:
+   ```bash
+   composer install
+   ```
+
+3. Update `config.php` with the new server's database settings.
+
+4. Run migrations:
+   ```bash
+   composer run migrate
+   ```
+
+5. Configure the web server to point at the project root or `public/`.
+
+6. Open the app in a browser and upload the workbook.
+
+## Notes For Future Stages
+
+- Keep the processing logic out of the template.
+- Add new calculated fields in `SpreadsheetRowProcessor`.
+- Add new schema fields only if JSONB is no longer sufficient.
+- If later stages need multiple import histories, stop truncating and switch to batch filtering in the UI.
+- If the workbook structure changes, update header detection in `SpreadsheetReader`.
+
+## Current Caveats
+
+- PostgreSQL credentials must be correct in `config.php`.
+- The app currently expects the database to exist before migration.
+- The import path uses PhpSpreadsheet, so Composer remains required.
+- Large workbooks should continue to use pagination in the preview table.
+
+## Working Assumptions
+
+- The header names remain stable.
+- The example workbook is representative of the real import structure.
+- `Revenue Type` should always be ignored.
+- Future stages will extend the current batch/import model rather than replace it.

 # Warner-Vistex-Automater
 
+Stage 1 of a Bootstrap-based PHP app that uploads an Excel workbook, processes the rows, stores the imported data in PostgreSQL, and previews the imported rows in a paginated table.
+
+## Features
+
+- Upload `.xls` or `.xlsx` files.
+- Validate required spreadsheet headers before import.
+- Wipe previous imported rows before each new import.
+- Compute the stage 1 derived fields during import.
+- Store normalized imported data plus calculated data in PostgreSQL using `jsonb`.
+- Process large imports in short chunks to avoid request timeouts.
+- Review imported rows in a Bootstrap table with pagination.
+- Show upload progress and import status in the browser.
+
+## Requirements
+
+- PHP 8.3 or newer
+- Composer
+- PostgreSQL
+
+## Setup
+
+1. Edit `config.php` and update the database settings if your host names differ from the defaults.
+   - Or set `DATABASE_URL`, for example:
+
+   ```bash
+   DATABASE_URL=postgres://postgres:postgres@host.docker.internal:5432/devdb?sslmode=prefer
+   ```
+
+   - The default host is `localhost` for CLI scripts and `postgres_db` for the web app.
+   - If your setup differs, `DATABASE_URL` is the easiest override.
+   - Set `APP_URL` if the app will run from a different folder or base URL than `http://localhost/warner/`.
+2. Install dependencies:
+
+```bash
+composer install
+```
+
+3. Run the database migration:
+
+```bash
+composer run migrate
+```
+
+4. Start the app:
+
+```bash
+php -S 127.0.0.1:8000 -t public
+```
+
+5. Open [http://127.0.0.1:8000](http://127.0.0.1:8000).
+
+## Import flow
+
+1. The app validates that a file was uploaded.
+2. The file must be an Excel workbook.
+3. Required columns are checked by header name.
+4. Existing imported rows are deleted in a transaction.
+5. The workbook rows are normalized and derived fields are calculated.
+6. The new rows are inserted and then displayed in the preview table.
+
+## Data model
+
+The schema uses two tables:
+
+- `import_batches` stores metadata for each import run.
+- `import_rows` stores the row payloads using `jsonb` for original, normalized, and calculated data.
+
+This keeps the model flexible for later import stages and additional derived fields.

+composer/pcre
+=============
+
+PCRE wrapping library that offers type-safe `preg_*` replacements.
+
+This library gives you a way to ensure `preg_*` functions do not fail silently, returning
+unexpected `null`s that may not be handled.
+
+As of 3.0 this library enforces [`PREG_UNMATCHED_AS_NULL`](#preg_unmatched_as_null) usage
+for all matching and replaceCallback functions, [read more below](#preg_unmatched_as_null)
+to understand the implications.
+
+It thus makes it easier to work with static analysis tools like PHPStan or Psalm as it
+simplifies and reduces the possible return values from all the `preg_*` functions which
+are quite packed with edge cases. As of v2.2.0 / v3.2.0 the library also comes with a
+[PHPStan extension](#phpstan-extension) for parsing regular expressions and giving you even better output types.
+
+This library is a thin wrapper around `preg_*` functions with [some limitations](#restrictions--limitations).
+If you are looking for a richer API to handle regular expressions have a look at
+[rawr/t-regx](https://packagist.org/packages/rawr/t-regx) instead.
+
+[![Continuous Integration](https://github.com/composer/pcre/workflows/Continuous%20Integration/badge.svg?branch=main)](https://github.com/composer/pcre/actions)
+
+
+Installation
+------------
+
+Install the latest version with:
+
+```bash
+$ composer require composer/pcre
+```
+
+
+Requirements
+------------
+
+* PHP 7.4.0 is required for 3.x versions
+* PHP 7.2.0 is required for 2.x versions
+* PHP 5.3.2 is required for 1.x versions
+
+
+Basic usage
+-----------
+
+Instead of:
+
+```php
+if (preg_match('{fo+}', $string, $matches)) { ... }
+if (preg_match('{fo+}', $string, $matches, PREG_OFFSET_CAPTURE)) { ... }
+if (preg_match_all('{fo+}', $string, $matches)) { ... }
+$newString = preg_replace('{fo+}', 'bar', $string);
+$newString = preg_replace_callback('{fo+}', function ($match) { return strtoupper($match[0]); }, $string);
+$newString = preg_replace_callback_array(['{fo+}' => fn ($match) => strtoupper($match[0])], $string);
+$filtered = preg_grep('{[a-z]}', $elements);
+$array = preg_split('{[a-z]+}', $string);
+```
+
+You can now call these on the `Preg` class:
+
+```php
+use Composer\Pcre\Preg;
+
+if (Preg::match('{fo+}', $string, $matches)) { ... }
+if (Preg::matchWithOffsets('{fo+}', $string, $matches)) { ... }
+if (Preg::matchAll('{fo+}', $string, $matches)) { ... }
+$newString = Preg::replace('{fo+}', 'bar', $string);
+$newString = Preg::replaceCallback('{fo+}', function ($match) { return strtoupper($match[0]); }, $string);
+$newString = Preg::replaceCallbackArray(['{fo+}' => fn ($match) => strtoupper($match[0])], $string);
+$filtered = Preg::grep('{[a-z]}', $elements);
+$array = Preg::split('{[a-z]+}', $string);
+```
+
+The main difference is if anything fails to match/replace/.., it will throw a `Composer\Pcre\PcreException`
+instead of returning `null` (or false in some cases), so you can now use the return values safely relying on
+the fact that they can only be strings (for replace), ints (for match) or arrays (for grep/split).
+
+Additionally the `Preg` class provides match methods that return `bool` rather than `int`, for stricter type safety
+when the number of pattern matches is not useful:
+
+```php
+use Composer\Pcre\Preg;
+
+if (Preg::isMatch('{fo+}', $string, $matches)) // bool
+if (Preg::isMatchAll('{fo+}', $string, $matches)) // bool
+```
+
+Finally the `Preg` class provides a few `*StrictGroups` method variants that ensure match groups
+are always present and thus non-nullable, making it easier to write type-safe code:
+
+```php
+use Composer\Pcre\Preg;
+
+// $matches is guaranteed to be an array of strings, if a subpattern does not match and produces a null it will throw
+if (Preg::matchStrictGroups('{fo+}', $string, $matches))
+if (Preg::matchAllStrictGroups('{fo+}', $string, $matches))
+```
+
+**Note:** This is generally safe to use as long as you do not have optional subpatterns (i.e. `(something)?`
+or `(something)*` or branches with a `|` that result in some groups not being matched at all).
+A subpattern that can match an empty string like `(.*)` is **not** optional, it will be present as an
+empty string in the matches. A non-matching subpattern, even if optional like `(?:foo)?` will anyway not be present in
+matches so it is also not a problem to use these with `*StrictGroups` methods.
+
+If you would prefer a slightly more verbose usage, replacing by-ref arguments by result objects, you can use the `Regex` class:
+
+```php
+use Composer\Pcre\Regex;
+
+// this is useful when you are just interested in knowing if something matched
+// as it returns a bool instead of int(1/0) for match
+$bool = Regex::isMatch('{fo+}', $string);
+
+$result = Regex::match('{fo+}', $string);
+if ($result->matched) { something($result->matches); }
+
+$result = Regex::matchWithOffsets('{fo+}', $string);
+if ($result->matched) { something($result->matches); }
+
+$result = Regex::matchAll('{fo+}', $string);
+if ($result->matched && $result->count > 3) { something($result->matches); }
+
+$newString = Regex::replace('{fo+}', 'bar', $string)->result;
+$newString = Regex::replaceCallback('{fo+}', function ($match) { return strtoupper($match[0]); }, $string)->result;
+$newString = Regex::replaceCallbackArray(['{fo+}' => fn ($match) => strtoupper($match[0])], $string)->result;
+```
+
+Note that `preg_grep` and `preg_split` are only callable via the `Preg` class as they do not have
+complex return types warranting a specific result object.
+
+See the [MatchResult](src/MatchResult.php), [MatchWithOffsetsResult](src/MatchWithOffsetsResult.php), [MatchAllResult](src/MatchAllResult.php),
+[MatchAllWithOffsetsResult](src/MatchAllWithOffsetsResult.php), and [ReplaceResult](src/ReplaceResult.php) class sources for more details.
+
+Restrictions / Limitations
+--------------------------
+
+Due to type safety requirements a few restrictions are in place.
+
+- matching using `PREG_OFFSET_CAPTURE` is made available via `matchWithOffsets` and `matchAllWithOffsets`.
+  You cannot pass the flag to `match`/`matchAll`.
+- `Preg::split` will also reject `PREG_SPLIT_OFFSET_CAPTURE` and you should use `splitWithOffsets`
+  instead.
+- `matchAll` rejects `PREG_SET_ORDER` as it also changes the shape of the returned matches. There
+  is no alternative provided as you can fairly easily code around it.
+- `preg_filter` is not supported as it has a rather crazy API, most likely you should rather
+  use `Preg::grep` in combination with some loop and `Preg::replace`.
+- `replace`, `replaceCallback` and `replaceCallbackArray` do not support an array `$subject`,
+  only simple strings.
+- As of 2.0, the library always uses `PREG_UNMATCHED_AS_NULL` for matching, which offers [much
+  saner/more predictable results](#preg_unmatched_as_null). As of 3.0 the flag is also set for
+  `replaceCallback` and `replaceCallbackArray`.
+
+#### PREG_UNMATCHED_AS_NULL
+
+As of 2.0, this library always uses PREG_UNMATCHED_AS_NULL for all `match*` and `isMatch*`
+functions. As of 3.0 it is also done for `replaceCallback` and `replaceCallbackArray`.
+
+This means your matches will always contain all matching groups, either as null if unmatched
+or as string if it matched.
+
+The advantages in clarity and predictability are clearer if you compare the two outputs of
+running this with and without PREG_UNMATCHED_AS_NULL in $flags:
+
+```php
+preg_match('/(a)(b)*(c)(d)*/', 'ac', $matches, $flags);
+```
+
+| no flag | PREG_UNMATCHED_AS_NULL |
+| --- | --- |
+| array (size=4)              | array (size=5) |
+| 0 => string 'ac' (length=2) |   0 => string 'ac' (length=2) |
+| 1 => string 'a' (length=1)  |   1 => string 'a' (length=1) |
+| 2 => string '' (length=0)   |   2 => null |
+| 3 => string 'c' (length=1)  |   3 => string 'c' (length=1) |
+|                             |   4 => null |
+| group 2 (any unmatched group preceding one that matched) is set to `''`. You cannot tell if it matched an empty string or did not match at all | group 2 is `null` when unmatched and a string if it matched, easy to check for |
+| group 4 (any optional group without a matching one following) is missing altogether. So you have to check with `isset()`, but really you want `isset($m[4]) && $m[4] !== ''` for safety unless you are very careful to check that a non-optional group follows it | group 4 is always set, and null in this case as there was no match, easy to check for with `$m[4] !== null` |
+
+PHPStan Extension
+-----------------
+
+To use the PHPStan extension if you do not use `phpstan/extension-installer` you can include `vendor/composer/pcre/extension.neon` in your PHPStan config.
+
+The extension provides much better type information for $matches as well as regex validation where possible.

+
+## Unstable Branch
+
+The `main` branch is not stable. Please see the
+[releases](https://github.com/maennchen/ZipStream-PHP/releases) for a stable
+version.
+
+## Overview
+
+A fast and simple streaming zip file downloader for PHP. Using this library will
+save you from having to write the Zip to disk. You can directly send it to the
+user, which is much faster. It can work with S3 buckets or any PSR7 Stream.
+
+Please see the [LICENSE](LICENSE) file for licensing and warranty information.
+
+## Installation
+
+Simply add a dependency on maennchen/zipstream-php to your project's
+`composer.json` file if you use Composer to manage the dependencies of your
+project. Use following command to add the package to your project's dependencies:
+
+```bash
+composer require maennchen/zipstream-php
+```
+
+## Usage
+
+For detailed instructions, please check the
+[Documentation](https://maennchen.github.io/ZipStream-PHP/).
+
+```php
+// Autoload the dependencies
+require 'vendor/autoload.php';
+
+// create a new zipstream object
+$zip = new ZipStream\ZipStream(
+    outputName: 'example.zip',
+
+    // enable output of HTTP headers
+    sendHttpHeaders: true,
+);
+
+// create a file named 'hello.txt'
+$zip->addFile(
+    fileName: 'hello.txt',
+    data: 'This is the contents of hello.txt',
+);
+
+// add a file named 'some_image.jpg' from a local file 'path/to/image.jpg'
+$zip->addFileFromPath(
+    fileName: 'some_image.jpg',
+    path: 'path/to/image.jpg',
+);
+
+// finish the zip stream
+$zip->finish();
+```
+
+### Callback Output
+
+You can stream ZIP data to a custom callback function instead of directly to the browser:
+
+```php
+use ZipStream\ZipStream;
+use ZipStream\Stream\CallbackStreamWrapper;
+
+// Stream to a callback function with proper file handling
+$outputFile = fopen('output.zip', 'wb');
+$backupFile = fopen('backup.zip', 'wb');
+
+$zip = new ZipStream(
+    outputStream: CallbackStreamWrapper::open(function (string $data) use ($outputFile, $backupFile) {
+        // Handle ZIP data as it's generated
+        fwrite($outputFile, $data);
+        
+        // Send to multiple destinations efficiently
+        echo $data; // Browser
+        fwrite($backupFile, $data); // Backup file
+    }),
+    sendHttpHeaders: false,
+);
+
+$zip->addFile('hello.txt', 'Hello World!');
+$zip->finish();
+
+// Clean up resources
+fclose($outputFile);
+fclose($backupFile);
+```
+
+## Questions
+
+**💬 Questions? Please Read This First!**

+
+## Upgrade to version 3.1.2
+
+- Minimum PHP Version: `8.2`
+
+## Upgrade to version 3.0.0
+
+### General
+
+- Minimum PHP Version: `8.1`
+- Only 64bit Architecture is supported.
+- The class `ZipStream\Option\Method` has been replaced with the enum
+  `ZipStream\CompressionMethod`.
+- Most classes have been flagged as `@internal` and should not be used from the
+  outside.
+  If you're using internal resources to extend this library, please open an
+  issue so that a clean interface can be added & published.
+  The externally available classes & enums are:
+  - `ZipStream\CompressionMethod`
+  - `ZipStream\Exception*`
+  - `ZipStream\ZipStream`
+
+### Archive Options
+
+- The class `ZipStream\Option\Archive` has been replaced in favor of named
+  arguments in the `ZipStream\ZipStream` constructor.
+- The archive options `largeFileSize` & `largeFileMethod` has been removed. If
+  you want different `compressionMethods` based on the file size, you'll have to
+  implement this yourself.
+- The archive option `httpHeaderCallback` changed the type from `callable` to
+  `Closure`.
+- The archive option `zeroHeader` has been replaced with the option
+  `defaultEnableZeroHeader` and can be overridden for every file. Its default
+  value changed from `false` to `true`.
+- The archive option `statFiles` was removed since the library no longer checks
+  filesizes this way.
+- The archive option `deflateLevel` has been replaced with the option
+  `defaultDeflateLevel` and can be overridden for every file.
+- The first argument (`name`) of the `ZipStream\ZipStream` constructor has been
+  replaced with the named argument `outputName`.
+- Headers are now also sent if the `outputName` is empty. If you do not want to
+  automatically send http headers, set `sendHttpHeaders` to `false`.
+
+### File Options
+
+- The class `ZipStream\Option\File` has been replaced in favor of named
+  arguments in the `ZipStream\ZipStream->addFile*` functions.
+- The file option `method` has been renamed to `compressionMethod`.
+- The file option `time` has been renamed to `lastModificationDateTime`.
+- The file option `size` has been renamed to `maxSize`.

+Adding Content-Length header
+=============
+
+Adding a ``Content-Length`` header for ``ZipStream`` can be achieved by
+using the options ``SIMULATION_STRICT`` or ``SIMULATION_LAX`` in the
+``operationMode`` parameter.
+
+In the ``SIMULATION_STRICT`` mode, ``ZipStream`` will not allow to calculate the
+size based on reading the whole file. ``SIMULATION_LAX`` will read the whole
+file if necessary.
+
+``SIMULATION_STRICT`` is therefore useful to make sure that the size can be
+calculated efficiently.
+
+.. code-block:: php
+    use ZipStream\OperationMode;
+    use ZipStream\ZipStream;
+
+    $zip = new ZipStream(
+        operationMode: OperationMode::SIMULATE_STRICT, // or SIMULATE_LAX
+        defaultEnableZeroHeader: false,
+        sendHttpHeaders: true,
+        outputStream: $stream,
+    );
+
+    // Normally add files
+    $zip->addFile('sample.txt', 'Sample String Data');
+
+    // Use addFileFromCallback and exactSize if you want to defer opening of
+    // the file resource
+    $zip->addFileFromCallback(
+        'sample.txt',
+        exactSize: 18,
+        callback: function () {
+            return fopen('...');

+
+    // Read resulting file size
+    $size = $zip->finish();
+    
+    // Tell it to the browser
+    header('Content-Length: '. $size);

+Usage with FlySystem
+===============
+
+For saving or uploading the generated zip, you can use the
+`Flysystem <https://flysystem.thephpleague.com>`_ package, and its many

+Compressing large files to S3 compatible storages
+=============
+
+S3 compatible storages usually have a limitation of 5 GiB when using single upload. When generating larger zips, the
+solution is to use a `multi-part upload`_.
+
+.. _multi-part upload: <https://github.com/awsdocs/aws-doc-sdk-examples/blob/75a8bf8536d436db91ec5de1ba0ed80fd258e904/php/example_code/s3/s3-multipart-upload-using-lowlevel-php-sdk-api.php>`
+
+We can implement a `PSR-7 stream <https://www.php-fig.org/psr/psr-7/>`_ that buffers ZipStream's output and uploads
+to S3 in chunks.

+                // No need to slice the buffer because we don't have enough data.
+                $result = $this->buffer;
+                $this->buffer = '';
+                $this->bufferSize = 0;
+            } else {
+                // Slice up the result to provide a subset of the buffer.
+                $result = substr($this->buffer, 0, $length);
+                $this->buffer = substr($this->buffer, $length);
+                $this->bufferSize -= $length;

+        {
+            return $key ? null : [];

+    }
+
+Then, we can use it with ZipStream to compress the files and upload the parts to the storage.

+Usage with nginx
+=============
+
+If you are using nginx as a webserver, it will try to buffer the response.
+So you'll want to disable this with a custom header:
+
+.. code-block:: php
+    header('X-Accel-Buffering: no');
+    # or with the Response class from Symfony
+    $response->headers->set('X-Accel-Buffering', 'no');
+
+Alternatively, you can tweak the
+`fastcgi cache parameters <https://nginx.org/en/docs/http/ngx_http_fastcgi_module.html#fastcgi_buffers>`_
+within nginx config.
+
+See `original issue <https://github.com/maennchen/ZipStream-PHP/issues/77>`_.

+
+For all parameters of the function see the API documentation.
+
+Example
+---------------
+

+Stream to Callback Function
+---------------------------
+
+The CallbackStreamWrapper allows you to stream ZIP data to a custom callback function,
+enabling flexible output handling such as streaming to multiple destinations,
+progress tracking, or data transformation.
+

+
+    use ZipStream\ZipStream;
+    use ZipStream\Stream\CallbackStreamWrapper;
+
+    // Example 1: Stream to multiple destinations with proper file handling

+    $logFile = fopen('transfer.log', 'ab');
+    
+    $zip = new ZipStream(
+        outputStream: CallbackStreamWrapper::open(function (string $data) use ($backupFile, $logFile) {
+            // Send to browser
+            echo $data;
+            
+            // Save to file efficiently
+            fwrite($backupFile, $data);
+            
+            // Log transfer progress
+            fwrite($logFile, "Transferred " . strlen($data) . " bytes\n");
+        }),
+        sendHttpHeaders: false,
+    );
+
+    $zip->addFile('hello.txt', 'Hello World!');
+    $zip->finish();
+    
+    // Clean up resources
+    fclose($backupFile);
+    fclose($logFile);
+
+.. code-block:: php
+
+    // Example 2: Progress tracking
+    $totalBytes = 0;
+    $zip = new ZipStream(
+        outputStream: CallbackStreamWrapper::open(function (string $data) use (&$totalBytes) {
+            $totalBytes += strlen($data);
+            reportProgress($totalBytes); // Report progress to your tracking system
+            
+            // Your actual output handling
+            echo $data;
+        }),
+        sendHttpHeaders: false,
+    );
+
+    $zip->addFile('large_file.txt', str_repeat('A', 10000));
+    $zip->finish();
+
+.. code-block:: php
+
+    // Example 3: Data transformation using PHP stream filters
+    // For data transformations, prefer PHP's built-in stream filters
+    $outputStream = fopen('php://output', 'w');
+    stream_filter_append($outputStream, 'convert.base64-encode');
+    
+    $zip = new ZipStream(
+        outputStream: $outputStream,
+        sendHttpHeaders: false,
+    );
+
+    $zip->addFile('secret.txt', 'Confidential data');
+    $zip->finish();
+    fclose($outputStream);
+
+.. note::
+   For data transformations, PHP's built-in stream filters are preferred over callback transformations. Stream filters operate at the stream level and maintain data integrity. You can register custom filters using ``stream_filter_register()`` for specialized transformations.

+Usage with Symfony
+===============
+
+Overview for using ZipStream in Symfony
+--------
+
+Using ZipStream in Symfony requires use of Symfony's ``StreamedResponse`` when
+used in controller actions.
+
+Wrap your call to the relevant ``ZipStream`` stream method (i.e. ``addFile``,
+``addFileFromPath``, ``addFileFromStream``) in Symfony's ``StreamedResponse``
+function passing in any required arguments for your use case.
+
+Using Symfony's ``StreamedResponse`` will allow Symfony to stream output from
+ZipStream correctly to users' browsers and avoid a corrupted final zip landing
+on the users' end.
+
+Example for using ``ZipStream`` in a controller action to zip stream files
+stored in an AWS S3 bucket by key:
+
+.. code-block:: php
+
+    use Symfony\Component\HttpFoundation\StreamedResponse;
+    use Aws\S3\S3Client;
+    use ZipStream;
+
+    //...
+
+    /**
+    * @Route("/zipstream", name="zipstream")
+    */
+    public function zipStreamAction()
+    {
+        // sample test file on s3
+        $s3keys = array(
+        "ziptestfolder/file1.txt"
+        );
+
+        $s3Client = $this->get('app.amazon.s3'); //s3client service
+        $s3Client->registerStreamWrapper(); //required
+
+        // using StreamedResponse to wrap ZipStream functionality
+        // for files on AWS s3.
+        $response = new StreamedResponse(function() use($s3keys, $s3Client)
+        {
+            // Define suitable options for ZipStream Archive.
+            // this is needed to prevent issues with truncated zip files
+            //initialise zipstream with output zip filename and options.
+            $zip = new ZipStream\ZipStream(
+                outputName: 'test.zip',
+                defaultEnableZeroHeader: true,
+                contentType: 'application/octet-stream',
+            );
+
+            //loop keys - useful for multiple files
+            foreach ($s3keys as $key) {
+                // Get the file name in S3 key so we can save it to the zip
+                //file using the same name.
+                $fileName = basename($key);
+
+                // concatenate s3path.
+                // replace with your bucket name or get from parameters file.
+                $bucket = 'bucketname';
+                $s3path = "s3://" . $bucket . "/" . $key;
+
+                //addFileFromStream
+                if ($streamRead = fopen($s3path, 'r')) {
+                    $zip->addFileFromStream(
+                        fileName: $fileName,
+                        stream: $streamRead,
+                    );
+                } else {
+                    die('Could not open stream for reading');
+                }
+            }
+
+            $zip->finish();
+
+        });
+
+        return $response;
+    }
+
+In the above example, files on AWS S3 are being streamed from S3 to the Symfon
+application via ``fopen`` call when the s3Client has ``registerStreamWrapper``
+applied. This stream is then passed to ``ZipStream`` via the
+``addFileFromStream`` function, which ZipStream then streams as a zip to the
+client browser via Symfony's ``StreamedResponse``. No Zip is created server
+side, which makes this approach a more efficient solution for streaming zips to
+the client browser especially for larger files.
+
+For the above use case you will need to have installed
+`aws/aws-sdk-php-symfony <https://github.com/aws/aws-sdk-php-symfony>`_ to
+support accessing S3 objects in your Symfony web application. This is not
+required for locally stored files on you server you intend to stream via
+``ZipStream``.
+
+See official Symfony documentation for details on
+`Symfony's StreamedResponse <https://symfony.com/doc/current/components/http_foundation.html#streaming-a-response>`_ 
+``Symfony\Component\HttpFoundation\StreamedResponse``.
+
+Note from `S3 documentation <https://docs.aws.amazon.com/sdk-for-php/v3/developer-guide/s3-stream-wrapper.html>`_:
+
+    Streams opened in "r" mode only allow data to be read from the stream, and
+    are not seekable by default. This is so that data can be downloaded from
+    Amazon S3 in a truly streaming manner, where previously read bytes do not
+    need to be buffered into memory. If you need a stream to be seekable, you
+    can pass seekable into the stream context options of a function.
+
+Make sure to configure your S3 context correctly!
+
+Uploading a file
+--------
+
+You need to add correct permissions
+(see `#120 <https://github.com/maennchen/ZipStream-PHP/issues/120>`_)
+
+**example code**
+
+
+.. code-block:: php
+
+    $path = "s3://{$adapter->getBucket()}/{$this->getArchivePath()}";
+
+    // the important bit
+    $outputContext = stream_context_create([
+        's3' => ['ACL' => 'public-read'],
+    ]);
+
+    fopen($path, 'w', null, $outputContext);

+
+Installation
+---------------
+
+Simply add a dependency on ``maennchen/zipstream-php`` to your project's
+``composer.json`` file if you use Composer to manage the dependencies of your
+project. Use following command to add the package to your project's
+dependencies:
+
+.. code-block:: sh
+   composer require maennchen/zipstream-php
+
+If you want to use``addFileFromPsr7Stream```
+(``Psr\Http\Message\StreamInterface``) or use a stream instead of a
+``resource`` as ``outputStream``, the following dependencies must be installed
+as well:
+
+.. code-block:: sh
+   composer require psr/http-message guzzlehttp/psr7
+
+If ``composer install`` yields the following error, your installation is missing
+the `mbstring extension <https://www.php.net/manual/en/book.mbstring.php>`_,
+either `install it <https://www.php.net/manual/en/mbstring.installation.php>`_
+or run the following command:
+
+.. code-block::
+    Your requirements could not be resolved to an installable set of packages.
+
+    Problem 1
+        - Root composer.json requires PHP extension ext-mbstring * but it is
+          missing from your system. Install or enable PHP's mbstrings extension.
+
+.. code-block:: sh
+   composer require symfony/polyfill-mbstring
+
+Usage Intro
+---------------
+
+Here's a simple example:
+
+.. code-block:: php
+
+   // Autoload the dependencies
+   require 'vendor/autoload.php';
+
+   // create a new zipstream object
+   $zip = new ZipStream\ZipStream(
+      outputName: 'example.zip',
+
+      // enable output of HTTP headers
+      sendHttpHeaders: true,
+   );
+
+   // create a file named 'hello.txt'
+   $zip->addFile(
+      fileName: 'hello.txt',
+      data: 'This is the contents of hello.txt',
+   );
+
+   // add a file named 'some_image.jpg' from a local file 'path/to/image.jpg'
+   $zip->addFileFromPath(
+      fileName: 'some_image.jpg',
+      path: 'path/to/image.jpg',
+   );
+
+   // add a file named 'goodbye.txt' from an open stream resource
+   $filePointer = tmpfile();
+   fwrite($filePointer, 'The quick brown fox jumped over the lazy dog.');
+   rewind($filePointer);
+   $zip->addFileFromStream(
+      fileName: 'goodbye.txt',
+      stream: $filePointer,
+   );
+   fclose($filePointer);

+   // add a file named 'streamfile.txt' from the body of a `guzzle` response
+   // Setup with `psr/http-message` & `guzzlehttp/psr7` dependencies required.
+   $zip->addFileFromPsr7Stream(
+      fileName: 'streamfile.txt',
+      stream: $response->getBody(),

+
+   // finish the zip stream
+   $zip->finish();
+
+You can also add comments, modify file timestamps, and customize (or
+disable) the HTTP headers. It is also possible to specify the storage method
+when adding files, the current default storage method is ``DEFLATE``
+i.e files are stored with Compression mode 0x08.
+
+Known Issues
+---------------
+
+The native Mac OS archive extraction tool prior to macOS 10.15 might not open
+archives in some conditions. A workaround is to disable the Zip64 feature with
+the option ``enableZip64: false``. This limits the archive to 4 Gb and 64k files
+but will allow users on macOS 10.14 and below to open them without issue.
+See `#116 <https://github.com/maennchen/ZipStream-PHP/issues/116>`_.
+
+The linux ``unzip`` utility might not handle properly unicode characters.
+It is recommended to extract with another tool like
+`7-zip <https://www.7-zip.org/>`_.
+See `#146 <https://github.com/maennchen/ZipStream-PHP/issues/146>`_.
+
+It is the responsibility of the client code to make sure that files are not
+saved with the same path, as it is not possible for the library to figure it out
+while streaming a zip.
+See `#154 <https://github.com/maennchen/ZipStream-PHP/issues/154>`_.

+/**
+ * Streamed, dynamically generated zip archives.
+ *
+ * ## Usage
+ *
+ * Streaming zip archives is a simple, three-step process:
+ *
+ * 1.  Create the zip stream:
+ *
+ * ```php
+ * $zip = new ZipStream(outputName: 'example.zip');
+ * ```
+ *
+ * 2.  Add one or more files to the archive:
+ *
+ * ```php
+ * // add first file
+ * $zip->addFile(fileName: 'world.txt', data: 'Hello World');
+ *
+ * // add second file
+ * $zip->addFile(fileName: 'moon.txt', data: 'Hello Moon');
+ * ```
+ *
+ * 3.  Finish the zip stream:
+ *
+ * ```php
+ * $zip->finish();
+ * ```
+ *
+ * You can also add an archive comment, add comments to individual files,
+ * and adjust the timestamp of files. See the API documentation for each
+ * method below for additional information.
+ *
+ * ## Example
+ *
+ * ```php
+ * // create a new zip stream object
+ * $zip = new ZipStream(outputName: 'some_files.zip');
+ *
+ * // list of local files
+ * $files = array('foo.txt', 'bar.jpg');
+ *
+ * // read and add each file to the archive
+ * foreach ($files as $path)
+ *   $zip->addFileFromPath(fileName: $path, $path);
+ *
+ * // write archive footer to stream
+ * $zip->finish();
+ * ```
+ *
+ * @api

+     *
+     * When the zero header is set, the file is streamed into the output

+
+PHP Class Library for working with Complex numbers
+
+[![Build Status](https://github.com/MarkBaker/PHPComplex/workflows/main/badge.svg)](https://github.com/MarkBaker/PHPComplex/actions)
+[![Total Downloads](https://img.shields.io/packagist/dt/markbaker/complex)](https://packagist.org/packages/markbaker/complex)
+[![Latest Stable Version](https://img.shields.io/github/v/release/MarkBaker/PHPComplex)](https://packagist.org/packages/markbaker/complex)

+ - division
+    - division by
+    - division into
+
+together with functions for 
+
+ - theta (polar theta angle)

+
+# Installation
+
+```shell
+composer require markbaker/complex:^1.0
+```
+
+# Important BC Note
+
+If you've previously been using procedural calls to functions and operations using this library, then from version 3.0 you should use [MarkBaker/PHPComplexFunctions](https://github.com/MarkBaker/PHPComplexFunctions) instead (available on packagist as [markbaker/complex-functions](https://packagist.org/packages/markbaker/complex-functions)).
+
+You'll need to replace `markbaker/complex`in your `composer.json` file with the new library, but otherwise there should be no difference in the namespacing, or in the way that you have called the Complex functions in the past, so no actual code changes are required.
+
+```shell
+composer require markbaker/complex-functions:^3.0
+```
+
+You should not reference this library (`markbaker/complex`) in your `composer.json`, composer wil take care of that for you.
+
+# Usage
+
+To create a new complex object, you can provide either the real, imaginary and suffix parts as individual values, or as an array of values passed passed to the constructor; or a string representing the value. e.g
+
+```php
+$real = 1.23;
+$imaginary = -4.56;
+$suffix = 'i';
+
+$complexObject = new Complex\Complex($real, $imaginary, $suffix);
+```
+or as an array
+```php
+$real = 1.23;
+$imaginary = -4.56;
+$suffix = 'i';
+
+$arguments = [$real, $imaginary, $suffix];
+
+$complexObject = new Complex\Complex($arguments);
+```
+or as a string
+```php
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+```
+
+Complex objects are immutable: whenever you call a method or pass a complex value to a function that returns a complex value, a new Complex object will be returned, and the original will remain unchanged.
+This also allows you to chain multiple methods as you would for a fluent interface (as long as they are methods that will return a Complex result).
+
+## Performing Mathematical Operations
+
+To perform mathematical operations with Complex values, you can call the appropriate method against a complex value, passing other values as arguments
+
+```php
+$complexString1 = '1.23-4.56i';
+$complexString2 = '2.34+5.67i';
+
+$complexObject = new Complex\Complex($complexString1);
+echo $complexObject->add($complexString2);
+```
+
+or use the static Operation methods
+```php
+$complexString1 = '1.23-4.56i';
+$complexString2 = '2.34+5.67i';
+
+echo Complex\Operations::add($complexString1, $complexString2);
+```
+If you want to perform the same operation against multiple values (e.g. to add three or more complex numbers), then you can pass multiple arguments to any of the operations.
+
+You can pass these arguments as Complex objects, or as an array, or string that will parse to a complex object.
+
+## Using functions
+
+When calling any of the available functions for a complex value, you can either call the relevant method for the Complex object
+```php
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+echo $complexObject->sinh();
+```
+
+or use the static Functions methods
+```php
+$complexString = '1.23-4.56i';
+
+echo Complex\Functions::sinh($complexString);
+```
+As with operations, you can pass these arguments as Complex objects, or as an array or string that will parse to a complex object.
+
+
+In the case of the `pow()` function (the only implemented function that requires an additional argument) you need to pass both arguments when calling the function
+
+```php
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+echo Complex\Functions::pow($complexObject, 2);
+```
+or pass the additional argument when calling the method
+```php
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+echo $complexObject->pow(2);
+```

+
+# Installation
+
+```shell
+composer require markbaker/matrix:^3.0
+```
+
+# Important BC Note
+
+If you've previously been using procedural calls to functions and operations using this library, then from version 3.0 you should use [MarkBaker/PHPMatrixFunctions](https://github.com/MarkBaker/PHPMatrixFunctions) instead (available on packagist as [markbaker/matrix-functions](https://packagist.org/packages/markbaker/matrix-functions)).
+
+You'll need to replace `markbaker/matrix`in your `composer.json` file with the new library, but otherwise there should be no difference in the namespacing, or in the way that you have called the Matrix functions in the past, so no actual code changes are required.
+
+```shell
+composer require markbaker/matrix-functions:^1.0
+```
+
+You should not reference this library (`markbaker/matrix`) in your `composer.json`, composer wil take care of that for you.
+
+# Usage
+
+To create a new Matrix object, provide an array as the constructor argument
+
+```php
+$grid = [
+    [16,  3,  2, 13],
+    [ 5, 10, 11,  8],
+    [ 9,  6,  7, 12],
+    [ 4, 15, 14,  1],
+];
+
+$matrix = new Matrix\Matrix($grid);
+```
+The `Builder` class provides helper methods for creating specific matrices, specifically an identity matrix of a specified size; or a matrix of a specified dimensions, with every cell containing a set value.
+```php
+$matrix = Matrix\Builder::createFilledMatrix(1, 5, 3);
+```
+Will create a matrix of 5 rows and 3 columns, filled with a `1` in every cell; while
+```php
+$matrix = Matrix\Builder::createIdentityMatrix(3);
+```
+will create a 3x3 identity matrix.
+
+
+Matrix objects are immutable: whenever you call a method or pass a grid to a function that returns a matrix value, a new Matrix object will be returned, and the original will remain unchanged. This also allows you to chain multiple methods as you would for a fluent interface (as long as they are methods that will return a Matrix result).
+
+## Performing Mathematical Operations
+
+To perform mathematical operations with Matrices, you can call the appropriate method against a matrix value, passing other values as arguments
+
+```php
+$matrix1 = new Matrix\Matrix([
+    [2, 7, 6],
+    [9, 5, 1],
+    [4, 3, 8],
+]);
+$matrix2 = new Matrix\Matrix([
+    [1, 2, 3],
+    [4, 5, 6],
+    [7, 8, 9],
+]);
+
+var_dump($matrix1->multiply($matrix2)->toArray());
+```
+or pass all values to the appropriate static method
+```php
+$matrix1 = new Matrix\Matrix([
+    [2, 7, 6],
+    [9, 5, 1],
+    [4, 3, 8],
+]);
+$matrix2 = new Matrix\Matrix([
+    [1, 2, 3],
+    [4, 5, 6],
+    [7, 8, 9],
+]);
+
+var_dump(Matrix\Operations::multiply($matrix1, $matrix2)->toArray());
+```
+You can pass in the arguments as Matrix objects, or as arrays.
+
+If you want to perform the same operation against multiple values (e.g. to add three or more matrices), then you can pass multiple arguments to any of the operations.
+
+## Using functions
+
+When calling any of the available functions for a matrix value, you can either call the relevant method for the Matrix object
+```php
+$grid = [
+    [16,  3,  2, 13],
+    [ 5, 10, 11,  8],
+    [ 9,  6,  7, 12],
+    [ 4, 15, 14,  1],
+];
+
+$matrix = new Matrix\Matrix($grid);
+
+echo $matrix->trace();
+```
+or you can call the static method, passing the Matrix object or array as an argument 
+```php
+$grid = [
+    [16,  3,  2, 13],
+    [ 5, 10, 11,  8],
+    [ 9,  6,  7, 12],
+    [ 4, 15, 14,  1],
+];
+
+$matrix = new Matrix\Matrix($grid);
+echo Matrix\Functions::trace($matrix);
+```
+```php
+$grid = [
+    [16,  3,  2, 13],
+    [ 5, 10, 11,  8],
+    [ 9,  6,  7, 12],
+    [ 4, 15, 14,  1],
+];
+
+echo Matrix\Functions::trace($grid);
+```
+
+## Decomposition
+
+The library also provides classes for matrix decomposition. You can access these using
+```php
+$grid = [
+    [1, 2],
+    [3, 4],
+];
+
+$matrix = new Matrix\Matrix($grid);
+
+$decomposition = new Matrix\Decomposition\QR($matrix);
+$Q = $decomposition->getQ();
+$R = $decomposition->getR();
+```
+
+or alternatively us the `Decomposition` factory, identifying which form of decomposition you want to use
+```php
+$grid = [
+    [1, 2],
+    [3, 4],
+];
+
+$matrix = new Matrix\Matrix($grid);
+
+$decomposition = Matrix\Decomposition\Decomposition::decomposition(Matrix\Decomposition\Decomposition::QR, $matrix);
+$Q = $decomposition->getQ();
+$R = $decomposition->getR();
+```

+
+OpenSpout is a community driven fork of `box/spout`, a PHP library to read and write spreadsheet files
+(CSV, XLSX and ODS), in a fast and scalable way. Unlike other file readers or writers, it is capable of processing
+very large files, while keeping the memory usage really low (less than 3MB).
+
+## Documentation
+
+Documentation can be found at [`docs/`](docs).
+
+## Upgrade from `box/spout:v3` to `openspout/openspout:v3`
+
+1. Replace `box/spout` with `openspout/openspout` in your `composer.json`
+2. Replace `Box\Spout` with `OpenSpout` in your code
+
+## Upgrade guide
+
+Version 4 introduced new functionality but also some breaking changes. If you want to upgrade your OpenSpout codebase
+please consult the [Upgrade guide](UPGRADE.md).

+# Upgrade guide
+
+## Upgrading from 3.x to 4.0
+
+Beginning with v4, only actively supported [PHP version](https://www.php.net/supported-versions.php) will be supported.
+Removing support for EOLed PHP versions as well adding support for new PHP versions will be included in MINOR releases.
+
+### Most notable changes
+
+1. OpenSpout is now fully typed
+2. Classes and interfaces not consumed by the user are now marked as `@internal`
+3. Classes used by the user are all `final`
+
+### Reader & Writer objects
+
+Both readers and writers have to be naturally instantiated with `new` keyword, passing the eventual needed `Options`
+class as the first argument:
+
+```php
+use OpenSpout\Reader\CSV\Reader;
+use OpenSpout\Reader\CSV\Options;
+
+$options = new Options();
+$options->FIELD_DELIMITER = '|';
+$options->FIELD_ENCLOSURE = '@';
+$reader = new Reader($options);
+```
+
+### Cell types on writes
+
+Cell types are now handled with separate classes:
+
+```php
+use OpenSpout\Common\Entity\Cell;
+use OpenSpout\Common\Entity\Row;
+
+$row = new Row([
+    new Cell\BooleanCell(true),
+    new Cell\DateIntervalCell(new DateInterval('P1D')),
+    new Cell\DateTimeCell(new DateTimeImmutable('now')),
+    new Cell\EmptyCell(null),
+    new Cell\FormulaCell('=SUM(A1:A2)'),
+    new Cell\NumericCell(3),
+    new Cell\StringCell('foo'),
+]);
+```
+
+Auto-typing is still available though:
+
+```php
+use OpenSpout\Common\Entity\Cell;
+use OpenSpout\Common\Entity\Row;
+
+$cell = Cell::fromValue(true); // Instance of Cell\BooleanCell
+
+$row = Row::fromValues([
+    true,
+    new DateInterval('P1D'),
+    new DateTimeImmutable('now'),
+    null,
+    '=SUM(A1:A2)',
+    3,
+    'foo',
+]);
+```
+
+## Upgrading from 2.x to 3.0
+
+OpenSpout 3.0 introduced several backwards-incompatible changes. The upgrade from OpenSpout 2.x to 3.0 must therefore
+be done with caution.
+This guide is meant to ease this process.
+
+### Most notable changes
+
+In 2.x, styles were applied per row; it was therefore impossible to apply different styles to cells in the same row.
+With the 3.0 version, this is now possible: each cell can have its own style.
+
+OpenSpout 3.0 tries to enforce better typing. For instance, instead of using/returning generic arrays, OpenSpout now
+makes use of specific `Row` and `Cell` objects that can encapsulate more data such as type, style, value.
+
+Finally, **_OpenSpout 3.2 only supports PHP 7.2 and above_**, as other PHP versions are no longer supported by the
+community.
+
+### Reader changes
+
+Creating a reader should now be done through the Reader `ReaderEntityFactory`, instead of using the `ReaderFactory`.
+Also, the `ReaderFactory::create($type)` method was removed and replaced by methods for each reader:
+
+```php
+use OpenSpout\Reader\Common\Creator\ReaderEntityFactory; // namespace is no longer "OpenSpout\Reader"
+
+$reader = ReaderEntityFactory::createXLSXReader(); // replaces ReaderFactory::create(Type::XLSX)
+$reader = ReaderEntityFactory::createCSVReader();  // replaces ReaderFactory::create(Type::CSV)
+$reader = ReaderEntityFactory::createODSReader();  // replaces ReaderFactory::create(Type::ODS)
+```
+
+When iterating over the spreadsheet rows, OpenSpout now returns `Row` objects, instead of an array containing row
+values. Accessing the row values should now be done this way:
+
+```php
+foreach ($reader->getSheetIterator() as $sheet) {
+    foreach ($sheet->getRowIterator() as $row) { // $row is a "Row" object, not an array
+        $rowAsArray = $row->toArray();  // this is the 2.x equivalent
+        // OR
+        $cellsArray = $row->getCells(); // this can be used to get access to cells' details
+        ... 
+    }
+}
+```
+
+### Writer changes
+
+Writer creation follows the same change as the reader. It should now be done through the Writer `WriterEntityFactory`,
+instead of using the `WriterFactory`.
+Also, the `WriterFactory::create($type)` method was removed and replaced by methods for each writer:
+
+```php
+use OpenSpout\Writer\Common\Creator\WriterEntityFactory; // namespace is no longer "OpenSpout\Writer"
+
+$writer = WriterEntityFactory::createXLSXWriter(); // replaces WriterFactory::create(Type::XLSX)
+$writer = WriterEntityFactory::createCSVWriter();  // replaces WriterFactory::create(Type::CSV)
+$writer = WriterEntityFactory::createODSWriter();  // replaces WriterFactory::create(Type::ODS)
+```
+
+Adding rows is also done differently: instead of passing an array, the writer now takes in a `Row` object (or an
+array of `Row`). Creating such objects can easily be done this way:
+```php
+// Adding a row from an array of values (2.x equivalent)
+$cellValues = ['foo', 12345];
+$row1 = WriterEntityFactory::createRowFromArray($cellValues, $rowStyle);
+
+// Adding a row from an array of Cell
+$cell1 = WriterEntityFactory::createCell('foo', $cellStyle1); // this cell has its own style
+$cell2 = WriterEntityFactory::createCell(12345, $cellStyle2); // this cell has its own style
+$row2 = WriterEntityFactory::createRow([$cell1, $cell2]);
+
+$writer->addRows([$row1, $row2]);
+```
+
+### Namespace changes for styles
+
+The namespaces for styles have changed. Styles are still created by using a `builder` class.
+
+For the builder, please update your import statements to use the following namespaces:
+
+    OpenSpout\Writer\Common\Creator\Style\StyleBuilder
+    OpenSpout\Writer\Common\Creator\Style\BorderBuilder
+
+The `Style` base class and style definitions like `Border`, `BorderPart` and `Color` also have a new namespace.
+
+If your are using these classes directly via an import statement in your code, please use the following namespaces:
+
+    OpenSpout\Common\Entity\Style\Border
+    OpenSpout\Common\Entity\Style\BorderPart
+    OpenSpout\Common\Entity\Style\Color
+    OpenSpout\Common\Entity\Style\Style
+
+### Handling of empty rows
+
+In 2.x, empty rows were not added to the spreadsheet.
+In 3.0, `addRow` now always writes a row to the spreadsheet: when the row does not contain any cells, an empty row
+is created in the sheet.

+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com)
+and this project adheres to [Semantic Versioning](https://semver.org). This is always true of the master branch. Some earlier branches, including the branch from which you are reading this file, remain supported and security fixes are applied to them; if the security fix represents a breaking change, it may have to be applied as a minor or patch version.
+
+## 2026-06-06 - 3.10.6
+
+### Security Note
+
+- File::prohibitWrappers and Drawing::setPath now reject phar paths with extra leading slashes (e.g. phar:///…) that escaped the prior parse_url-based filter. No security exploit was possible even with the extra slashes. Backport of [PR #4876](https://github.com/PHPOffice/PhpSpreadsheet/pull/4876)
+
+### Fixed
+
+- Third-party security patches.
+- Php 8.6 deprecation in Mpdf. Backport of [PR #4878](https://github.com/PHPOffice/PhpSpreadsheet/pull/4878)
+- Ability to reuse disconnected spreadsheet. Backport of [PR #4880](https://github.com/PHPOffice/PhpSpreadsheet/pull/4880)
+
+## 2026-04-09 - 3.10.5
+
+### Fixed
+
+- Security patches.
+
+## 2026-04-09 - 3.10.4
+
+### Fixed
+
+- Security patches.
+- Option to whitelist external images. Security-related backport of [PR #4793](https://github.com/PHPOffice/PhpSpreadsheet/pull/4793)
+
+## 2026-01-10 - 3.10.3
+
+### Changed
+
+- Evaluation of WEBSERVICE no longer requires external client, but will use oldCalculatedValue unless the request is for a domain in a user-supplied whitelist. Security-related backport of [PR #4751](https://github.com/PHPOffice/PhpSpreadsheet/pull/4751)
+
+### Deprecated
+
+- Settings methods setHttpClient, unsetHttpClient, getHttpClient, and getRequestFactory are no longer used. No replacement.
+
+### Fixed
+
+- Changes to WEBSERVICE. Backport of [PR #4751](https://github.com/PHPOffice/PhpSpreadsheet/pull/4751)
+
+## 2025-11-24 - 3.10.2
+
+### Added
+
+- Formal support for Php8.5.
+
+### Fixed
+
+ - Php8.5 deprecates use of null as array index. [PR #4636](https://github.com/PHPOffice/PhpSpreadsheet/pull/4636)
+ - Fix 'do not trigger `Undefined array key "x"`'. [Issue #4668](https://github.com/PHPOffice/PhpSpreadsheet/issues/4668) [PR #4679](https://github.com/PHPOffice/PhpSpreadsheet/pull/4679) Backport of [PR #4669](https://github.com/PHPOffice/PhpSpreadsheet/pull/4669)
+
+## 2025-09-03 - 3.10.1
+
+### Added
+
+- Option for Readers to create a new blank sheet if none match LoadSheetsOnly list. [PR #4623](https://github.com/PHPOffice/PhpSpreadsheet/pull/4623) Backport of [PR #4618](https://github.com/PHPOffice/PhpSpreadsheet/pull/4618).
+- Remove `imagedestroy` from MemoryDrawing. Backport of [PR #4625](https://github.com/PHPOffice/PhpSpreadsheet/pull/4625).
+
+### Fixed
+
+ - Compatibility changes for Php 8.5. [Issue #4600](https://github.com/PHPOffice/PhpSpreadsheet/issues/4600) [PR #4613](https://github.com/PHPOffice/PhpSpreadsheet/pull/4613) [PR #4595](https://github.com/PHPOffice/PhpSpreadsheet/pull/4595) [PR #4589](https://github.com/PHPOffice/PhpSpreadsheet/pull/4589)
+
+## 2025-08-10 - 3.10.0
+
+### Breaking Changes
+
+- Images will be loaded from an external source (e.g. http://example.com/img.png) only if the reader is explicitly set to allow it via `$reader->setAllowExternalImages(true)`. We do not believe that loading of external images is a widely used feature. This is a necessary change for security purposes.

+
+## 2.0.0 - 2024-01-04
+
+### BREAKING CHANGE
+
+- Typing was strengthened by leveraging native typing. This should not change any behavior. However, if you implement
+  any interfaces or inherit from any classes, you will need to adapt your typing accordingly. If you use static analysis 
+  tools such as PHPStan or Psalm, new errors might be found. If you find actual bugs because of the new typing, please
+  open a PR that fixes it with a **detailed** explanation of the reason. We'll try to merge and release typing-related
+  fixes quickly in the coming days. [PR #3718](https://github.com/PHPOffice/PhpSpreadsheet/pull/3718)
+- All deprecated things have been removed, for details, see [816b91d0b4](https://github.com/PHPOffice/PhpSpreadsheet/commit/816b91d0b4a0c7285a9e3fc88c58f7730d922044)

+
+## 1.23.0 - 2022-04-24
+
+### Added
+
+- Ods Writer support for Freeze Pane [Issue #2013](https://github.com/PHPOffice/PhpSpreadsheet/issues/2013) [PR #2755](https://github.com/PHPOffice/PhpSpreadsheet/pull/2755)
+- Ods Writer support for setting column width/row height (including the use of AutoSize) [Issue #2346](https://github.com/PHPOffice/PhpSpreadsheet/issues/2346) [PR #2753](https://github.com/PHPOffice/PhpSpreadsheet/pull/2753)
+- Introduced CellAddress, CellRange, RowRange and ColumnRange value objects that can be used as an alternative to a string value (e.g. `'C5'`, `'B2:D4'`, `'2:2'` or `'B:C'`) in appropriate contexts.
+- Implementation of the FILTER(), SORT(), SORTBY() and UNIQUE() Lookup/Reference (array) functions.
+- Implementation of the ISREF() Information function.
+- Added support for reading "formatted" numeric values from Csv files; although default behaviour of reading these values as strings is preserved.
+
+  (i.e a value of "12,345.67" can be read as numeric `12345.67`, not simply as a string `"12,345.67"`, if the `castFormattedNumberToNumeric()` setting is enabled.
+
+  This functionality is locale-aware, using the server's locale settings to identify the thousands and decimal separators.
+
+- Support for two cell anchor drawing of images. [#2532](https://github.com/PHPOffice/PhpSpreadsheet/pull/2532) [#2674](https://github.com/PHPOffice/PhpSpreadsheet/pull/2674)
+- Limited support for Xls Reader to handle Conditional Formatting:
+
+  Ranges and Rules are read, but style is currently limited to font size, weight and color; and to fill style and color.
+
+- Add ability to suppress Mac line ending check for CSV [#2623](https://github.com/PHPOffice/PhpSpreadsheet/pull/2623)
+- Initial support for creating and writing Tables (Xlsx Writer only) [PR #2671](https://github.com/PHPOffice/PhpSpreadsheet/pull/2671)
+
+  See `/samples/Table` for examples of use.
+
+  Note that PreCalculateFormulas needs to be disabled when saving spreadsheets containing tables with formulae (totals or column formulae).
+
+### Changed
+
+- Gnumeric Reader now loads number formatting for cells.
+- Gnumeric Reader now correctly identifies selected worksheet and selected cells in a worksheet.
+- Some Refactoring of the Ods Reader, moving all formula and address translation from Ods to Excel into a separate class to eliminate code duplication and ensure consistency.
+- Make Boolean Conversion in Csv Reader locale-aware when using the String Value Binder.
+
+  This is determined by the Calculation Engine locale setting.
+
+  (i.e. `"Vrai"` wil be converted to a boolean `true` if the Locale is set to `fr`.)
+- Allow `psr/simple-cache` 2.x
+
+### Deprecated
+
+- All Excel Function implementations in `Calculation\Functions` (including the Error functions) have been moved to dedicated classes for groups of related functions. See the docblocks against all the deprecated methods for details of the new methods to call instead. At some point, these old classes will be deleted.
+- Worksheet methods that reference cells "byColumnandRow". All such methods have an equivalent that references the cell by its address (e.g. '`E3'` rather than `5, 3`).
+
+  These functions now accept either a cell address string (`'E3')` or an array with columnId and rowId (`[5, 3]`) or a new `CellAddress` object as their `cellAddress`/`coordinate` argument.
+  This includes the methods:
+  - `setCellValueByColumnAndRow()` use the equivalent `setCellValue()`
+  - `setCellValueExplicitByColumnAndRow()` use the equivalent `setCellValueExplicit()`
+  - `getCellByColumnAndRow()` use the equivalent `getCell()`
+  - `cellExistsByColumnAndRow()` use the equivalent `cellExists()`
+  - `getStyleByColumnAndRow()` use the equivalent `getStyle()`
+  - `setBreakByColumnAndRow()` use the equivalent `setBreak()`
+  - `mergeCellsByColumnAndRow()` use the equivalent `mergeCells()`
+  - `unmergeCellsByColumnAndRow()` use the equivalent `unmergeCells()`
+  - `protectCellsByColumnAndRow()` use the equivalent `protectCells()`
+  - `unprotectCellsByColumnAndRow()` use the equivalent `unprotectCells()`
+  - `setAutoFilterByColumnAndRow()` use the equivalent `setAutoFilter()`
+  - `freezePaneByColumnAndRow()` use the equivalent `freezePane()`
+  - `getCommentByColumnAndRow()` use the equivalent `getComment()`
+  - `setSelectedCellByColumnAndRow()` use the equivalent `setSelectedCells()`
+
+  This change provides more consistency in the methods (not every "by cell address" method has an equivalent "byColumnAndRow" method);
+  and the "by cell address" methods often provide more flexibility, such as allowing a range of cells, or referencing them by passing the defined name of a named range as the argument.
+
+### Removed
+
+- Nothing
+
+### Fixed
+
+- Make allowance for the AutoFilter dropdown icon in the first row of an Autofilter range when using Autosize columns. [Issue #2413](https://github.com/PHPOffice/PhpSpreadsheet/issues/2413) [PR #2754](https://github.com/PHPOffice/PhpSpreadsheet/pull/2754)
+- Support for "chained" ranges (e.g. `A5:C10:C20:F1`) in the Calculation Engine; and also support for using named ranges with the Range operator (e.g. `NamedRange1:NamedRange2`) [Issue #2730](https://github.com/PHPOffice/PhpSpreadsheet/issues/2730) [PR #2746](https://github.com/PHPOffice/PhpSpreadsheet/pull/2746)
+- Update Conditional Formatting ranges and rule conditions when inserting/deleting rows/columns [Issue #2678](https://github.com/PHPOffice/PhpSpreadsheet/issues/2678) [PR #2689](https://github.com/PHPOffice/PhpSpreadsheet/pull/2689)
+- Allow `INDIRECT()` to accept row/column ranges as well as cell ranges [PR #2687](https://github.com/PHPOffice/PhpSpreadsheet/pull/2687)
+- Fix bug when deleting cells with hyperlinks, where the hyperlink was then being "inherited" by whatever cell moved to that cell address.
+- Fix bug in Conditional Formatting in the Xls Writer that resulted in a broken file when there were multiple conditional ranges in a worksheet.
+- Fix Conditional Formatting in the Xls Writer to work with rules that contain string literals, cell references and formulae.
+- Fix for setting Active Sheet to the first loaded worksheet when bookViews element isn't defined [Issue #2666](https://github.com/PHPOffice/PhpSpreadsheet/issues/2666) [PR #2669](https://github.com/PHPOffice/PhpSpreadsheet/pull/2669)
+- Fixed behaviour of XLSX font style vertical align settings [PR #2619](https://github.com/PHPOffice/PhpSpreadsheet/pull/2619)
+- Resolved formula translations to handle separators (row and column) for array functions as well as for function argument separators; and cleanly handle nesting levels.
+
+  Note that this method is used when translating Excel functions between `en_us` and other locale languages, as well as when converting formulae between different spreadsheet formats (e.g. Ods to Excel).
+
+  Nor is this a perfect solution, as there may still be issues when function calls have array arguments that themselves contain function calls; but it's still better than the current logic.
+- Fix for escaping double quotes within a formula [Issue #1971](https://github.com/PHPOffice/PhpSpreadsheet/issues/1971) [PR #2651](https://github.com/PHPOffice/PhpSpreadsheet/pull/2651)

+- Support for the Excel365 Math/Trig RANDARRAY() function [PR #2540](https://github.com/PHPOffice/PhpSpreadsheet/pull/2540)
+
+  Note that the Spill Operator is not yet supported in the Calculation Engine; but this can still be useful for defining array constants.
+- Improved support for Conditional Formatting Rules [PR #2491](https://github.com/PHPOffice/PhpSpreadsheet/pull/2491)
+  - Provide support for a wider range of Conditional Formatting Rules for Xlsx Reader/Writer:
+    - Cells Containing (cellIs)
+    - Specific Text (containing, notContaining, beginsWith, endsWith)
+    - Dates Occurring (all supported timePeriods)
+    - Blanks/NoBlanks
+    - Errors/NoErrors
+    - Duplicates/Unique
+    - Expression
+  - Provision of CF Wizards (for all the above listed rule types) to help create/modify CF Rules without having to manage all the combinations of types/operators, and the complexities of formula expressions, or the text/timePeriod attributes.
+
+    See [documentation](https://phpspreadsheet.readthedocs.io/en/latest/topics/conditional-formatting/) for details
+
+  - Full support of the above CF Rules for the Xlsx Reader and Writer; even when the file being loaded has CF rules listed in the `<extLst><ext><ConditionalFormattings>` element for the worksheet rather than the `<ConditionalFormatting>` element.

+- Basic implementation of the PERMUTATIONA() Statistical Function
+
+### Changed
+
+- Formula functions that previously called PHP functions directly are now processed through the Excel Functions classes; resolving issues with PHP8 stricter typing. [#1789](https://github.com/PHPOffice/PhpSpreadsheet/issues/1789)
+
+  The following MathTrig functions are affected:
+  `ABS()`, `ACOS()`, `ACOSH()`, `ASIN()`, `ASINH()`, `ATAN()`, `ATANH()`,
+  `COS()`, `COSH()`, `DEGREES()` (rad2deg), `EXP()`, `LN()` (log), `LOG10()`,

+
+  One TextData function is also affected: `REPT()` (str_repeat).
+- `formatAsDate` correctly matches language metadata, reverting c55272e
+- Formulae that previously crashed on sub function call returning excel error value now return said value.
+  The following functions are affected `CUMPRINC()`, `CUMIPMT()`, `AMORLINC()`,

+- Adapt some function error return value to match excel's error.
+  The following functions are affected `PPMT()`, `IPMT()`.
+
+### Deprecated
+
+- Calling many of the Excel formula functions directly rather than through the Calculation Engine.
+

+
+  This makes the logic in these classes easier to maintain; and will reduce the memory footprint required to execute formulae when calling these functions.

+- Fix on `CUMPRINC()`, `CUMIPMT()`, `AMORLINC()`, `AMORDEGRC()` usage. When those functions called one of `YEARFRAC()`, `PPMT()`, `IPMT()` and they would get back an error value (represented as a string), trying to use numeral operands (`+`, `/`, `-`, `*`) on said return value and a number (`float or `int`) would fail.

+- **IMPORTANT NOTE:** This Introduces a **BC break** in the handling of named ranges. Previously, a named range cell reference of `B2` would be treated identically to a named range cell reference of `$B2` or `B$2` or `$B$2` because the calculation engine treated then all as absolute references. These changes "fix" that, so the calculation engine now handles relative references in named ranges correctly.
+  This change that resolves previously incorrect behaviour in the calculation may affect users who have dynamically defined named ranges using relative references when they should have used absolute references.

+## 1.8.0 - 2019-07-01
+
+### Security Fix (CVE-2019-12331)
+
+- Detect double-encoded xml in the Security scanner, and reject as suspicious.
+- This change also broadens the scope of the `libxml_disable_entity_loader` setting when reading XML-based formats, so that it is enabled while the xml is being parsed and not simply while it is loaded.
+  On some versions of PHP, this can cause problems because it is not thread-safe, and can affect other PHP scripts running on the same server. This flag is set to true when instantiating a loader, and back to its original setting when the Reader is no longer in scope, or manually unset.
+- Provide a check to identify whether libxml_disable_entity_loader is thread-safe or not.
+
+  `XmlScanner::threadSafeLibxmlDisableEntityLoaderAvailability()`
+- Provide an option to disable the libxml_disable_entity_loader call through settings. This is not recommended as it reduces the security of the XML-based readers, and should only be used if you understand the consequences and have no other choice.
+

+# Want to contribute?
+
+If you would like to contribute, here are some notes and guidelines:
+
+ - All new development should be on feature/fix branches, which are then merged to the `master` branch once stable and approved; so the `master` branch is always the most up-to-date, working code
+ - If you are going to submit a pull request, please fork from `master`, and submit your pull request back as a fix/feature branch referencing the GitHub issue number
+ - Install (development) dependencies by running `composer install` inside your PhpSpreadsheet clone.
+ - The code must work with all PHP versions that we support.
+   - You can call `composer versions` to test version compatibility. 
+ - Code style should be maintained.
+   - `composer style` will identify any issues with Coding Style.
+   - `composer fix` will fix most issues with Coding Style.
+ - All code changes must be validated by `composer check`.
+ - Please include Unit Tests to verify that a bug exists, and that this PR fixes it.
+ - Please include Unit Tests to show that a new Feature works as expected.
+ - Please don't "bundle" several changes into a single PR; submit a PR for each discrete change/fix.
+ - Remember to update documentation if necessary.
+
+ - [Helpful article about forking](https://help.github.com/articles/fork-a-repo/ "Forking a GitHub repository")
+ - [Helpful article about pull requests](https://help.github.com/articles/using-pull-requests/ "Pull Requests")
+
+## Unit Tests
+
+When writing Unit Tests, please
+ - Always try to write Unit Tests for both the happy and unhappy paths.
+ - Put all assertions in the Test itself, not in an abstract class that the Test extends (even if this means code duplication between tests).
+ - Include any necessary `setup()` and `tearDown()` in the Test itself.
+ - If you change any global settings (such as system locale, or Compatibility Mode for Excel Function tests), make sure that you reset to the default in the `tearDown()`.
+ - Use the `ExcelError` functions in assertions for Excel Error values in Excel Function implementations.
+   <br />Not only does it reduce the risk of typos; but at some point in the future, ExcelError values will be an object rather than a string, and we won't then need to update all the tests.
+ - Don't over-complicate test code by testing happy and unhappy paths in the same test.
+
+This makes it easier to see exactly what is being tested when reviewing the PR. I want to be able to see it in the PR, not have to hunt in other unchanged classes to see what the test is doing.
+
+## How to release
+
+1. Complete CHANGELOG.md and commit
+2. Create an annotated tag
+    1. `git tag -a 1.2.3`
+    2. Tag subject must be the version number, eg: `1.2.3`
+    3. Tag body must be a copy-paste of the changelog entries.
+3. Push the tag with `git push --tags`, GitHub Actions will create a GitHub release automatically, and the release details will automatically be sent to packagist.
+4. By default, Github removes markdown headings in the Release Notes. You can either edit to restore these, or, probably preferably, change the default comment character on your system - `git config core.commentChar ";"`.
+
+> **Note:** Tagged releases are made from the `master` branch. Only in an emergency should a tagged release be made from the `release` branch. (i.e. cherry-picked hot-fixes.) However, there are 3 branches which have been updated to apply security patches, and those may be tagged if future security updates are needed.

+
+PhpSpreadsheet is a library written in pure PHP and offers a set of classes that
+allow you to read and write various spreadsheet file formats such as Excel and LibreOffice Calc.
+
+This branch (3.10.x) is maintained (for security and some bug fixes), but it is *not* the latest version of PhpSpreadsheet, and may therefore lack features and bug fixes found in the latest version.
+
+## PHP Version Support
+
+LTS: For maintained branches, support for PHP versions will only be maintained for a period of six months beyond the
+[end of life](https://www.php.net/supported-versions) of that PHP version.
+
+Currently the required PHP minimum version is PHP __8.1__, and we [will support that version](https://www.php.net/supported-versions.php) until 30th June 2026.
+
+See the `composer.json` for other requirements.
+
+## Installation
+
+See the [install instructions](https://phpspreadsheet.readthedocs.io/en/latest/#installation).
+
+## Documentation
+
+Read more about it, including install instructions, in the [official documentation](https://phpspreadsheet.readthedocs.io). Or check out the [API documentation](https://phpoffice.github.io/PhpSpreadsheet).
+
+Please ask your support questions on [StackOverflow](https://stackoverflow.com/questions/tagged/phpspreadsheet), or have a quick chat on [Gitter](https://gitter.im/PHPOffice/PhpSpreadsheet).
+
+## Patreon
+
+I am now running a [Patreon](https://www.patreon.com/MarkBaker) to support the work that I do on PhpSpreadsheet.
+
+Supporters will receive access to articles about working with PhpSpreadsheet, and how to use some of its more advanced features.
+
+Posts already available to Patreon supporters:
+ - The Dating Game
+   - A  look at how MS Excel (and PhpSpreadsheet) handle date and time values.
+- Looping the Loop
+    - Advice on Iterating through the rows and cells in a worksheet.
+
+And for Patrons at levels actively using PhpSpreadsheet:
+ - Behind the Mask
+   - A look at Number Format Masks.
+
+The Next Article (currently Work in Progress):
+ - Formula for Success
+   - How to debug formulae that don't produce the expected result.
+
+
+My aim is to post at least one article each month, taking a detailed look at some feature of MS Excel and how to use that feature in PhpSpreadsheet, or on how to perform different activities in PhpSpreadsheet.
+
+Planned posts for the future include topics like:
+ - Tables
+ - Structured References
+ - AutoFiltering
+ - Array Formulae
+ - Conditional Formatting
+ - Data Validation
+ - Value Binders
+ - Images
+ - Charts
+
+After a period of six months exclusive to Patreon supporters, articles will be incorporated into the public documentation for the library.
+
+## PHPExcel vs PhpSpreadsheet ?
+
+PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
+
+Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet `master` branch.
+
+Do you need to migrate? There is [an automated tool](/docs/topics/migration-from-PHPExcel.md) for that.

+     *                                If year is between 0 (zero) and 1899 (inclusive), Excel adds that
+     *                                value to 1900 to calculate the year. For example, DATE(108,1,2)

+     *                                value as the year. For example, DATE(2008,1,2) returns January 2,
+     *                                2008.
+     *                                If year is less than 0 or is 10000 or greater, Excel returns the
+     *                                #NUM! error value.
+     * @param array|float|int|string $month A positive or negative integer representing the month of the year

+     *                                If month is greater than 12, month adds that number of months to
+     *                                the first month in the year specified. For example, DATE(2008,14,2)
+     *                                returns the serial number representing February 2, 2009.
+     *                                If month is less than 1, month subtracts the magnitude of that

+     * This routine calculates the LOG(GAMMA) function for a positive real argument X.
+     * Computation is based on an algorithm outlined in references 1 and 2.
+     * The program uses rational functions that theoretically approximate LOG(GAMMA)
+     * to at least 18 significant decimal digits. The approximation for X > 12 is from
+     * reference 3, while approximations for X < 12.0 are similar to those in reference
+     * 1, but are unpublished. The accuracy achieved depends on the arithmetic system,
+     * the compiler, the intrinsic functions, and proper selection of the
+     * machine-dependent constants.
+     * </p>
+     * <p>
+     * Error returns: <br />
+     * The program returns the value XINF for X .LE. 0.0 or when overflow would occur.

+// Adapted from Excel_Spreadsheet_Reader developed by users bizon153,
+// trex005, and mmp11 (SourceForge.net)
+// https://sourceforge.net/projects/phpexcelreader/
+// Primary changes made by canyoncasa (dvc) for ParseXL 1.00 ...
+//     Modelled moreso after Perl Excel Parse/Write modules
+//     Added Parse_Excel_Spreadsheet object
+//         Reads a whole worksheet or tab as row,column array or as
+//         associated hash of indexed rows and named column fields
+//     Added variables for worksheet (tab) indexes and names
+//     Added an object call for loading individual woorksheets
+//     Changed default indexing defaults to 0 based arrays
+//     Fixed date/time and percent formats
+//     Includes patches found at SourceForge...
+//         unicode patch by nobody
+//         unpack("d") machine depedency patch by matchy
+//         boundsheet utf16 patch by bjaenichen
+//     Renamed functions for shorter names
+//     General code cleanup and rigor, including <80 column width
+//     Included a testcase Excel file and PHP example calls
+//     Code works for PHP 5.x
+
+// Primary changes made by canyoncasa (dvc) for ParseXL 1.10 ...
+// http://sourceforge.net/tracker/index.php?func=detail&aid=1466964&group_id=99160&atid=623334
+//     Decoding of formula conditions, results, and tokens.
+//     Support for user-defined named cells added as an array "namedcells"
+//         Patch code for user-defined named cells supports single cells only.
+//         NOTE: this patch only works for BIFF8 as BIFF5-7 use a different
+//         external sheet reference structure

+/**
+ * <code>
+ * Header/Footer Formatting Syntax taken from Office Open XML Part 4 - Markup Language Reference, page 1970:.
+ *
+ * There are a number of formatting codes that can be written inline with the actual header / footer text, which
+ * affect the formatting in the header or footer.
+ *
+ * Example: This example shows the text "Center Bold Header" on the first line (center section), and the date on
+ * the second line (center section).
+ *         &CCenter &"-,Bold"Bold&"-,Regular"Header_x000A_&D
+ *
+ * General Rules:
+ * There is no required order in which these codes must appear.
+ *
+ * The first occurrence of the following codes turns the formatting ON, the second occurrence turns it OFF again:
+ * - strikethrough
+ * - superscript
+ * - subscript
+ * Superscript and subscript cannot both be ON at same time. Whichever comes first wins and the other is ignored,
+ * while the first is ON.
+ * &L - code for "left section" (there are three header / footer locations, "left", "center", and "right"). When
+ * two or more occurrences of this section marker exist, the contents from all markers are concatenated, in the
+ * order of appearance, and placed into the left section.
+ * &P - code for "current page #"
+ * &N - code for "total pages"
+ * &font size - code for "text font size", where font size is a font size in points.
+ * &K - code for "text font color"
+ * RGB Color is specified as RRGGBB
+ * Theme Color is specifed as TTSNN where TT is the theme color Id, S is either "+" or "-" of the tint/shade
+ * value, NN is the tint/shade value.
+ * &S - code for "text strikethrough" on / off
+ * &X - code for "text super script" on / off
+ * &Y - code for "text subscript" on / off
+ * &C - code for "center section". When two or more occurrences of this section marker exist, the contents
+ * from all markers are concatenated, in the order of appearance, and placed into the center section.
+ *
+ * &D - code for "date"
+ * &T - code for "time"
+ * &G - code for "picture as background"
+ * &U - code for "text single underline"
+ * &E - code for "double underline"
+ * &R - code for "right section". When two or more occurrences of this section marker exist, the contents
+ * from all markers are concatenated, in the order of appearance, and placed into the right section.
+ * &Z - code for "this workbook's file path"
+ * &F - code for "this workbook's file name"
+ * &A - code for "sheet tab name"
+ * &+ - code for add to page #.
+ * &- - code for subtract from page #.
+ * &"font name,font type" - code for "text font name" and "text font type", where font name and font type
+ * are strings specifying the name and type of the font, separated by a comma. When a hyphen appears in font
+ * name, it means "none specified". Both of font name and font type can be localized values.
+ * &"-,Bold" - code for "bold font style"
+ * &B - also means "bold font style".
+ * &"-,Regular" - code for "regular font style"
+ * &"-,Italic" - code for "italic font style"
+ * &I - also means "italic font style"
+ * &"-,Bold Italic" code for "bold italic font style"
+ * &O - code for "outline style"
+ * &H - code for "shadow style"

+PHP FIG Simple Cache PSR
+========================
+
+This repository holds all interfaces related to PSR-16.
+
+Note that this is not a cache implementation of its own. It is merely an interface that describes a cache implementation. See [the specification](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-16-simple-cache.md) for more details.
+
+You can find implementations of the specification by looking for packages providing the [psr/simple-cache-implementation](https://packagist.org/providers/psr/simple-cache-implementation) virtual package.
