3.0.0

• Support Symfony 7
• Drop support for Symfony < 6.4
• Test with PHP 8.2 and 8.3
• Drop support for PHP < 8.1
• Switched to PSR-17 message factories
• Switched some places to PSR-18 HTTP client. The main functionality needs the Httplug Async Client specification. There is no PSR for asynchronous clients.
• Parameter and return type declarations where possible.
• Ignore empty tag lists passed to TagCapable::invalidateTags so you don't need to check if there are tags or not.
