Major new features 🚀

• Conditonal return types (pull requests), #3853, big thanks to @​rvanvelzen!
  • Allows return types in the form of @return ($i is positive-int ? non-empty-array : array) (don't forget the parentheses!)
  • Another possible form is with generic @template tags: @return (T is positive-int ? non-empty-array : array)
• int-mask<...> and int-mask-of<...> types (#1166), thanks @​rvanvelzen!
• Allow global constants as PHPDoc types (#1163), thanks @​rvanvelzen!
• Update php-8-stubs to know about PHP 8.1 function signature changes, #7017, #6448
• Make isset() and null-coalesce (??) operators consistent with each other (#1223), thanks @​rajyan!
  • New option checkDynamicProperties to restore the original stricter behaviour (#1234), thanks @​rajyan!

Bleeding edge 🔪

• Fully static reflection engine
  • After feedback is gathered and processed, this will be enabled for everyone later in PHPStan 1.x release cycle.
• Lower memory consumption thanks to breaking up of reference cycles
  • This is a BC break for rules that use 'parent', 'next', and 'previous' node attributes. Learn more »
  • In testing the memory consumption was reduced by 50–70 %.
• ArrayUnpackingRule (level 3) (#856), thanks @​canvural!
• Rules for checking direct calls to __construct() (level 2) (#1208), #7022, thanks @​muno92!
• checkMissingIterableValueType: false no longer does anything (phpstan/phpstan-src@50d0c8e)

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

• Fix issue with dynamic properties (#1237), #3171, thanks @​rajyan!
