Support for PHP 8.5 and coroutine-friendly library compatibility

[sahdoio]

Hi everyone,
I’m planning upgrades across some production services and I’d like to understand how new PHP versions are added and supported in this project, I have a few specific questions:

Process to add support for a new PHP version, can you describe the steps you follow to accept and test a new runtime version to support PHP 8.5, do you require a PR, CI changes, or a release branch?

Roadmap and timeline, where can I follow the roadmap or planned support for PHP versions, is there a public tracker, milestone, or roadmap doc?

Compatibility concerns for production apps, if we update our production apps to PHP 8.5, what problems should we expect, are there known breaking changes that would impact typical Swoole/Hyperf setups?

Coroutine-friendly libraries, some libraries we depend on will need rewrites to be coroutine-friendly, do you offer guidance or examples for migrating libraries to be coroutine-safe, are there recommendation lists for async-safe replacements?

Thanks for any pointers.
