This release closes 25 issues! 🥳

Major new features 🚀

• Fully static reflection! (#1265)
  • PHPStan used runtime reflection before June 2020 (https://phpstan.org/blog/zero-config-analysis-with-static-reflection) and hybrid reflection after that
  • Analysed code is no longer executed, except for files referenced in bootstrapFiles and files sections in Composer autoload configuration
  • This prevents various fatal errors during analysis
  • Also solves edge cases like #7077, #7019
  • Native reflection is always BetterReflection adapter (phpstan/phpstan-src@ef60339)
  • Global constants no longer have to be defined in bootstrapFiles (#1277, #1282), thanks @kukulich!
• Implement @phpstan-consistent-constructor and add a new rule as another way to supress new static() issues (#1296), thanks @canvural!
  • See the update article: https://phpstan.org/blog/solving-phpstan-error-unsafe-usage-of-new-static
• Offset/index access PHPDoc type (phpstan/phpdoc-parser#119, #1318), #7094, thanks @rvanvelzen!

Bleeding edge 🔪

• Unresolvable parameters (#1319), thanks @rvanvelzen!
• Support @readonly property and @immutable class PHPDoc (#1295, #1335), #4082, thanks @herndlm!

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

Improvements 🔧

• Allow setting error format in configuration file (#841), thanks @ruudk!
• Deprecated PHPStan\Type\ConstantTypeHelper::getTypeFromValue(). Instead of going from runtime value -> PHPStan type, use PHPStan\Reflection\InitializerExprTypeResolver::getType() to go from Expr -> PHPStan type. In case you have Scope available, use Scope::getType().
• Read default values from php-8-stubs and jetbrains/phpstorm-stubs (phpstan/phpstan-src@7ce177e)
• Normalize named arguments when calling extensions (#1301, #1313), #5866, thanks @staabm!
• implement str-case functions return type extension (#1325), thanks @staabm!
• ClearResultCacheCommand: allow --debug flag (phpstan/phpstan-src@5f5b96d)
