Term name converted to term id filter removed? I am currently working on a view that should show all items from a content type with the given taxonomy term name (not id) in the url.

While this was easy to achieve in D7 (by following the answer on this question: Views contextual filters taxonomy name), I can't seem to find the validator filter now.
The predefined view "taxonomy term" might have the answer.
It will always show results based on the TID. 
I believe that if you just add an alias to your URL, it will work just fine. You can use the module pathauto to automatically create an alias.
