Are all bugfix releases of GNOME usually backported to NixOS stable, or does NixOS stable in general stay on a release as long as nothing major breaks?
Normally, bugfix releases of all applications should be backported to the current stable branch. And that includes GNOME bugfix releases.
In this case, a day after your comment someone added the “backport” tag to the PR, so that the nixpkgs-ci bot automatically creates a PR for the backport. However, because of a merge conflict the bot did not open a PR by itself.
I now fixed the conflict and created a new PR: [Backport release-25.11] GNOME updates 2026-01-24 by axodentally · Pull Request #488388 · NixOS/nixpkgs · GitHub .
To do that, I just used the commands the bot provided, however I cherry-picked the commits one-by-one to find the one with the merge conflict and then fixed it.
hopefully it gets merged soon (feel free to add a thumbs up to the PR).
