# Release 25.11 ("Xantusia", 2025.11/??) {#sec-release-25.11} ## Highlights {#sec-release-25.11-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 {#sec-release-25.11-new-modules} - [gtklock](https://github.com/jovanlanik/gtklock), a GTK-based lockscreen for Wayland. Available as [programs.gtklock](#opt-programs.gtklock.enable). ## Backward Incompatibilities {#sec-release-25.11-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](https://github.com/renovatebot/renovate/releases/tag/40.0.0) for breaking changes. ## Other Notable Changes {#sec-release-25.11-notable-changes} - `services.clamsmtp` is unmaintained and was removed from Nixpkgs.
