Improvements 🔧

• Support for union type as @template type bound (phpstan/phpstan-src@ac7b49e), #3769
• Support int and string as @template type bound (phpstan/phpstan-src@768bfab)
• Type-specifying extension for ReflectionClass::isSubclassOf() (phpstan/phpstan-src@d3b5d60), #4577
• Update BetterReflection to version that uses PHPStan namespace instead of random prefixed one (phpstan/phpstan-src@06ef13e). See rectorphp/rector#5665
• Update PhpStorm stubs (phpstan/phpstan-src@5aa8a55)
• Add PhpPropertyReflection::getNativeReflection() (phpstan/phpstan-src@5fad625)

Bleeding edge 🔪

• Type inference of new $string leads to object, not mixed (phpstan/phpstan-src@78a9f05)

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.
