 ### New Features
 
 ### Bug fixes
+- Set ``highway-env`` version to 1.5 and ``setuptools to`` v65.5 for the CI
 - Removed `use_auth_token` for push to hub util
 - Reverted from v3 to v2 for HumanoidStandup, Reacher, InvertedPendulum and InvertedDoublePendulum since they were not part of the mujoco refactoring (see https://github.com/openai/gym/pull/1304)
