cache tags not available in version 2.0

I tried to use the cache feature and would like to clear the existing permissions when ever role is updated. but couldn't find anything related to this in docs. 

I just dig into the code and found that cache tags were available in ver 1.0 but not in v 2.0. any plan to incorporate this feature to 2.0 branch?

I'm using laravel 6 and laravel-acl 2.0.
