Code Review
This pull request upgrades the gymnasium dependency from version 1.1.1 to 1.2.2. The change is applied consistently across all relevant files, including setup.py, requirements.txt, and numerous dependency lock files. The version bump is in line with the PR's goal to move to a version that no longer supports Python 3.9. The changes appear correct and comprehensive. No issues were found in the provided patches.

Hi @aslonnie — it looks like the Windows build is currently failing due to a dependency resolution issue with gymnasium==1.2.2. I’ve included the relevant logs below for context: [2025-12-18T22:49:58Z] Downloading fastapi-0.121.0-py3-none-any.whl.metadata (28 kB)

[2025-12-18T22:49:58Z] ERROR: Cannot install gymnasium==1.2.2 because these package versions have conflicting dependencies.
[2025-12-18T22:49:58Z]
[2025-12-18T22:49:58Z] The conflict is caused by:
[2025-12-18T22:49:58Z] The user requested gymnasium==1.2.2
[2025-12-18T22:49:58Z] The user requested (constraint) gymnasium==1.2.2
[2025-12-18T22:49:58Z]
[2025-12-18T22:49:58Z] Additionally, some packages in these conflicts have no matching distributions available for your environment:
[2025-12-18T22:49:58Z] gymnasium
[2025-12-18T22:49:58Z]
[2025-12-18T22:49:58Z] To fix this you could try to:
[2025-12-18T22:49:58Z] 1. loosen the range of package versions you've specified
[2025-12-18T22:49:58Z] 2. remove package versions to allow pip to attempt to solve the dependency conflict
