 Changelog
 ==========
 
-Release 1.8.0a14 (WIP)
+Release 1.8.0 (2023-04-07)
 --------------------------
 
+.. warning::
+
+  Stable-Baselines3 (SB3) v1.8.0 will be the last one to use Gym as a backend.
+  Starting with v2.0.0, Gymnasium will be the default backend (though SB3 will have compatibility layers for Gym envs).
+  You can find a migration guide here: https://gymnasium.farama.org/content/migration-guide/.
+  If you want to try the SB3 v2.0 alpha version, you can take a look at `PR #1327 <https://github.com/DLR-RM/stable-baselines3/pull/1327>`_.
