Release notes

Sourced from phpstan/phpstan's releases.

0.12.79

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)

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.
