Improvements 🔧

• Improve DateInterval inference (#5486), #14479, thanks @VincentLanglet!
• Next autoindexes can be empty and setOffsetValueType with null offsetType returns ErrorType (phpstan/phpstan-src@5e793f7)

Bugfixes 🐛

• Process unrolled foreach iteration body in original context to let nested loops stabilize (#5559), #9332, #14543
• Preserve conditional expressions in invalidateExpression when requireMoreCharacters is true (#5560), #14545
• Recognize [$obj, $method] as callable when is_callable($obj, $method) is known true in scope (#5547), #4510, thanks @VincentLanglet and @staabm!
• Replace instead of union when writing to optional keys via union offset in ConstantArrayTypeBuilder (#5566), #14551
• Check isFirstClassCallable() before calling getArgs() on nested FuncCall nodes (#5564), #14550, thanks @staabm and @VincentLanglet!
• Preserve non-empty array guarantee in ConstantArrayType::setOffsetValueType when union key expansion produces all-optional keys (#5567), #14552, #14553

Performance 🏎️

• Cache methods in IntersectionType (phpstan/phpstan-src@c161e9f)
