Release 25.11 ("Xantusia", 2025.11/??)

Highlights

• Secure boot support can now be enabled for the Limine bootloader through {option}boot.loader.limine.secureBoot.enable. Bootloader install script signs the bootloader, then kernels are hashed during system rebuild and written to a config. This allows Limine to boot only the kernels installed through NixOS system.

New Modules

• gtklock, a GTK-based lockscreen for Wayland. Available as programs.gtklock.

• SuiteNumérique Docs, a collaborative note taking, wiki and documentation web platform and alternative to Notion or Outline. Available as services.lasuite-docs.

Backward Incompatibilities

• The services.polipo module has been removed as polipo is unmaintained and archived upstream.

• renovate was updated to v40. See the upstream release notes for breaking changes.

Other Notable Changes

• services.clamsmtp is unmaintained and was removed from Nixpkgs.
