Admins will be upgrading ORNL GitLab Servers on Saturday, 16 May 2026, from 7 AM until 11 AM EST. Repositories will experience intermittent outages during this time.
- GDM now allows multiple seats, which is useful for e.g. remote logins. Though we currently [limit this to five greeter instances](https://github.com/NixOS/nixpkgs/issues/458058).
-`papers` document viewer is now installed by default, replacing `evince`. Though we still include `evince` transitively by `sushi` (quick previewer used by Files/Nautilus) You can disable either using [](#opt-environment.gnome.excludePackages) and restore `evince` with [](#opt-programs.evince.enable).
-`showtime` video player is now installed by default, replacing `totem`. You can disable it using [](#opt-environment.gnome.excludePackages) and restore `totem` with [](#opt-environment.systemPackages).
- The `ibus` input method is now enabled by default, to ensure that dead keys continue to work like in GNOME <= 48. To change it, see [](#opt-i18n.inputMethod.enable) and [](#opt-i18n.inputMethod.type).
Refer to the [GNOME release notes](https://release.gnome.org/49/) for more details.
