This issue is to keep track of my todo list for the upcoming bundle version 8 (Symfony 8 support) 😀

The plan is, as usual:

• A new version of the bundle is released shortly after Symfony 8 is officially released. This typically happens in the same time frame when a new PHP version is released as well. So please be patient, until work is finished.
• A 8.x branch will eventually appear, with an ⚠unstable development state. It is not recommended to be used in production scenarios, as there will a lot of changes and rebasing on this branch. Use it at your own risk.

Features

• Change security factory priority to < -50 (-100?) -> AuthenticatorFactory priority #265

Codebase upgrades

• Remove deprecated properties/methods
• Upgrade codebase to PHP 8.x (min PHP version TBD) style where possible
• Upgrade code examples in the docs with PHP 8.x (min PHP version TBD) code style
• Upgrade notes
• Clean up code that is no longer needed and remove compatibility layers
• Update CONTRIBUTING.md on language features to be used
• Update .symfony.bundle.yaml
• Update version number and compatible Symfony versions in 8.x docs
• Drop old versions of dependencies
• Update mentions of "7.x" to "8.x" on the 8.x branch (i.e. docs and issue templates and gitsplit workflow)
• Update version guidance on 8.x branch
• Update "replace" section in composer.json
• Clean up the app
• Upgrade code style
• Check for skipped tests, whether these are still needed
• Working integration tests
• Update gitsplit config
• Update Pslam PHP version in psalm.xml
• Update PHP-CS-Sniffer PHP version in phpcs.xml.dist
• MockObject| -> MockObject&

Pre-Release Cleanup (once Symfony 8 stable is released)

• Remove minimum-stability and prefer-stable from composer.json files
• Remove temporary changes from composer.json files, i.e. @dev
• Rewrite commits to clean up fiddling with CI and dependencies

Release

• Change default branch on Github to 8.x
• Release 🥳
• Abandon version 6.x, update version guidance
• Update version guidance on 7.x branch

Post-Release

• Remove .symfony.bundle.yaml from 7.x
• Change default branch of sub-packages to 8.x
