Hi, we are @jopejoe1 and @leona-ya, the release managers for NixOS 25.11 ("Xantusia").

It's time for this release's Feature Freeze & Release Blockers. To make sure that this is going to be a stable and reliable release, please tell us about any release blockers here and add them to the 25.11 Blockers Project.

For context, the feature freezes are going to start on the following 2 dates:

• 2025-10-04 00:00 UTC 2025-10-11 00:00 UTC Restrict breaking changes to Release Critical Packages
• 2025-10-18 00:00 UTC 2025-10-25 00:00 UTC Restrict all breaking changes

So we encourage all teams to check in now and to mention possible blockers, so that we can get an overview of what's ahead of us.

Check-in

Please comment your status quo and possible issues as soon as possible. We'll check teams once they have checked in.

If you think some subsystem, person or team should be added or removed from this list, update maintainers/team-list.nix and your GitHub team members in time before the next feature freeze announcement.
