Release notes\r\n\r\nThis is another very minor bug release.\r\n\r\n### Bugs Fixes \r\n* As `reset` now returns `(obs, info)` then in the vector environments, this caused the final `step`'s info to be overwritten. Now, the final observation and info are contained within the info as \"final_observation\" and \"final_info\" @pseudo-rnd-thoughts \r\n* Adds warnings when trying to render without specifying the `render_mode` @younik \r\n* Updates Atari Preprocessing such that the wrapper can be pickled @vermouth1992 \r\n* Github CI was hardened to such that the CI just has read permissions @sashashura \r\n* Clarify and fix typo in `GraphInstance` @ekalosak \r\n "},"readme":true,"readme_zh":false,"news":[],"stale":false,"snapshot_at":"2026-11-10T09:35:25Z","history_start":"2026-09-06"}
