2.2.10

This release brings improved performance and reduced memory consumption, mainly thanks to:

• Forking parallel workers where available:
  • Instead of spawning processes with proc_open(), they are forked with pcntl_fork(), saving time to bootstrap PHPStan
  • This requires PHPStan Turbo extension (already present if you install PHPStan with Composer) and non-Windows OS
• Deduped objects held in memory by BetterReflection
• Turbo extension-accelerated directories symbols scanning which allowed us to remove caching of this data and locking in worker processes

Feel free to comment how PHPStan 2.2.9 vs. 2.2.10 perform on your project! 🚀

Bleeding edge 🔪

• Check written case of single-part class names imported with use statements (#6271), #12827, thanks @janedbal!

If you want to see the shape of things to come and adopt bleeding edge features early, you can include this config file in your project's phpstan.neon:

includes:
	- vendor/phpstan/phpstan/conf/bleedingEdge.neon

Of course, there are no backwards compatibility guarantees when you include this file. The behaviour and reported errors can change in minor versions with this file included. Learn more
