This version brings another 5-10 % faster performance! 🏎️

Improvements 🔧

• Remove PHP version constraint from the #[\Override] attribute rules (#4436), thanks @johnbillion!
• OverridingPropertyRule - take checkMissingOverrideMethodAttribute as default only on PHP 8.5+ (phpstan/phpstan-src@64e9776)
• Support StaticMethodParameterClosureTypeExtension for New_ expressions (#4819), thanks @ruudk!
• Improve inference on FuncCall === FuncCall (#4513), infer non-empty-string on strlen() == strlen() #13749, thanks @staabm!
• Don't lose known offset-types in array_merge() (#4554), thanks @staabm!

Bugfixes 🐛

• Fixed escaped hash in regex extended mode (#4814), thanks @dg!
• Fix closure type inference bug related to FNSR (phpstan/phpstan-src@66f2738), [2.1.35 regression] Closure parameter types no longer inferred from expected Closure signature #13993

Performance 🏎️

• Rework phpDoc inheritance to resolve through reflection instead of re-walking the hierarchy (#4829), Method should return class-string<T of Template> but returns class-string<T of Template> #10771
• TemplateTypeHelper: prevent unnecessary work (#4818), thanks @staabm!
• ConstantArrayType: prevent unnecessary work (#4811), thanks @staabm!
• ImpossibleCheckTypeHelper: Remove unnecessary late-resolving (#4816), thanks @staabm!
• Prevent duplicate logic execution for createMethod with includingAnnotations: true if @method does not exist (phpstan/phpstan-src@d5da11e)
• Find all constant/method types per class at once (#4737), thanks @staabm!
• Speed up CombinationHelper (#4825), thanks @kaja47!
• MutatingScope: Faster createConditionalExpressions (#4831), thanks @staabm!
• Re-use ExpressionTypeHolder (#4832), thanks @staabm!
• IntersectionType cannot be void (#4835), thanks @staabm!
• Cache IntersectionType results (PHPStan breaks custom autoloader from loading dependencies for anonymous classes #4836) (#4836), thanks @staabm!
• Prevent unnecessary work in MutatingScope->mergeVariableHolders() (#4837), thanks @staabm!
• Simplify lowercase-string handling (Variable flagged as "might not be defined" when declared before an exception can be thrown. #4838) (#4838), thanks @staabm!

Function signature fixes 🤖

• NodeDependencies: cache normalized filenames (Memory consumption regression in 0.12.83 #4815) (#4815), thanks @staabm!

Internals 🔍

• Clarify new PhpPropertyReflection call with named arguments (phpstan/phpstan-src@0f6f059)
• Narrow type of reflection get*Type() after calling has*Type() (#4806), thanks @paulbalandan!
• Add regression test (#4824), @phpstan-ignore wrongly autodetects line / next-line #11598, thanks @takaram!
• No need to have generics in class constant-related messages (#4829), Method should return class-string<T of Template> but returns class-string<T of Template> #10771
