Bleeding edge 🔪

• ParamAttributesRule - promoted property attribute needs to target both parameters and properties (phpstan/phpstan-src@25d1552), False positive on mixed attribute usage on promoted property #10298
• More precise RecursiveIteratorIterator::__construct() parameter types (#2835), thanks @staabm!
• PhpDocParser: add config for lines in its AST & enable ignoring errors within PHPDocs (#2807), thanks @janedbal!

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
