+## New CodeJail Service implementation
+
+The Ulmo release introduced support for deploying a new
+implementation of the remote CodeJail service (openedx/codejail-service). The
+Verawood release completely removes support for deploying the old version of the
+service (edunext/codejailservice). Users should be mindful of the following
+points when upgrading:
+
+1. The new CodeJail service **requires** AppArmor 4 on the host machine.
+   AppArmor 4 is available on relatively new Debian based distributions (ubuntu
+   24.04, Debian Trixie, etc).
+2. AppArmor enforcement is no longer optional. The new CodeJail service performs
+   startup checks to ensure the sandbox is properly isolated and will not start
+   if the AppArmor profile is not loaded and configured.
+3. The new CodeJail service implementation is based on Django instead of Flask.
+   Any usage of the `codejail-*-settings` must be adjusted accordingly.
