Friendly ping @greg0ire :)

🤔 why are you targeting 2.1.x ?

🤔 why are you targeting 2.1.x ?

It was the default branch, and I don't know the rules about the phpdoc.
It can be considered as a patch, because it will fix some developper psalm issues.

You prefer 2.2.x ?

[greg0ire]

I think 2.2.x is appropriate indeed 👍 . Your proposal is more precise, but string was not wrong either.

[VincentLanglet]

Done

Thanks @VincentLanglet !
