    Allows to call the `validate` method statically

    As the validator implementation might not vary, I find it cumbersome to have to instantiate an object for the validator.

    In addition to being easier to write, this PR eliminates initialization of the same array several times if the validator is used several times.

    Using "composer require" means that it will automatically choose a semver constraint, and that it will also take care of not breaking the composer.json file (safer than manual update)

Releases(v2.0.0)

  • v2.0.0(Jan 30, 2022)

    👋 Hey, it's been a long time, right? Almost 8 years. I merged a PR to validate the callback type recently. I don't think this is a BC break but this library has been super stable for so long that I didn't want to take any risk. That's why I just released 2.0.0 and not 1.2.0. Let me know if everything works with PHP 8.x these days.

    Cheers, Will
