# PHP 8.3 support in Dotkernel Frontend

## TL;DR

To take advantage of PHP 8.3 support in the newest packages, the Dotkernel team updated the [Frontend](https://github.com/dotkernel/frontend) application to version 4.2.0.
As with the earlier Admin update, this required dropping support for PHP 8.1 and for the no-longer-available `PhpFileCache` class, until a replacement is implemented.

## What changed

- **Supports only PHP 8.2 and PHP 8.3**
  - Removed support for PHP 8.1
  - Updated CI workflows to remove PHP 8.1
- **Updated dependencies** in `composer.json` (`require` and `require-dev`), including packages such as `dotkernel/dot-annotated-services`, `dotkernel/dot-controller`, `dotkernel/dot-mail`, `mezzio/mezzio`, `phpunit/phpunit`, `rector/rector`, and `vimeo/psalm`.
- **Updated npm dependencies** in `packagist.json` - recommended to use npm v10.0.4 and Node.js v20.11.0.
- **Removed `PhpFileCache` usage** from configuration files (required due to the class no longer being available):
  - Updated `doctrine.global.php`
  - Removed the `use Doctrine\Common\Cache\PhpFileCache;` statement
  - Removed the parameters used by the `configuration` and `cache` cache settings
- **Fixed Psalm and PHPCS issues** - updated type hints and indentation.

Next on the roadmap: implementing these changes in the Dotkernel Frontend live projects and processing the feedback.
