-Due to a recent Amazon API deprecation, you need to install psiturk version 2.3.0 or later.
+psiTurk v3 has been released! See the migration guide at
+https://psiturk.readthedocs.io/en/latest/migrating.html
 
-v2.3.0 is python2 only, while versions of v2.3.x >= v2.3.1 support both python2 and python3.
+psiTurk v3 does not support the psiturk ad server. If you still need
+the psiTurk ad server, use psiTurk v2.3.12, and remove all HTML comments
+from your `ad.html` file. Versions less than v2.3.12 will not be able to post
+HITs due to a change implemented by the psiturk ad server's hosting provider.
