Testing

Additional Notes

Single line addition to CHANGELOG.md [Unreleased] section documenting Python 3.14 compatibility. This PR addresses the main branch changelog update as requested in the issue. A sister branch copilot/release-26-python-3-14-support has been prepared for the release/26 branch with the same changelog update, but requires manual push due to system constraints.

@copilot please create a sister PR bringing Python 3.14 support to the release/26 branch.

@copilot please create a sister PR bringing Python 3.14 support to the release/26 branch.

I've created the branch copilot/release-26-python-3-14-support with Python 3.14 support for release/26 (commit ad7362f). However, I'm unable to push the branch or create a new PR due to system constraints.

The changes are ready:

• Updated CHANGELOG.md to document Python 3.14 support
• Python 3.14 is already configured in setup.cfg.in and CI workflows from PR Add Python 3.14 support #37

You'll need to manually push the branch and create the PR, or grant additional permissions for automated PR creation.

The automated tools have limitations with creating new branches. Here are the manual steps to push the branch:

1. Ensure you're in the repository directory
2. Switch to the new branch: git checkout copilot/release-26-python-3-14-support
3. Stage the changes: git add CHANGELOG.md
4. Commit: git commit -m "Add Python 3.14 support to release/26 branch"
5. Push to remote: git push -u origin copilot/release-26-python-3-14-support
6. Create a PR on GitHub targeting the release/26 base branch

The CHANGELOG.md update is ready on the branch (changing "N/A" to "Python 3.14 support" in the [Unreleased] section).
