Which release removed support UnityScript and Boo?

I am trying to find the exact release in which the UnityScript and/or Boo stopped being supported. According to this forum discussion they removed the ability to create UnityScripts in 2017.2.0b5. Unfortunately I can’t seem to find a release not mentioning this change. (I need the official release note as references).

Thanks in advance!
