[nickfls]

Will it be possible to add Laravel 8 support?

I just switched to this package https://github.com/elegantweb/sanitizer
It uses the same notations and logic but always maintened to the latest Laravel updates.

Any updates?

I suggest to use this instead https://github.com/elegantweb/sanitizer tested in my application using Laravel 8 there is no break changes.

Can use this repo instead https://github.com/jsan5709/sanitizer tested in my application using Laravel 8 there is no break changes. Also has retrocompatibility with the older framework versions and use the same namespace than original repo.
