Release 24.05 (“Uakari”, 2024.05/??)

Support is planned until the end of December 2024, handing over to 24.11.

Highlights

In addition to numerous new and upgraded packages, this release has the following highlights:

• screen's module has been cleaned, and will now require you to set programs.screen.enable in order to populate screenrc and add the program to the environment.

New Services

• Guix, a functional package manager inspired by Nix. Available as services.guix.

• maubot, a plugin-based Matrix bot framework. Available as services.maubot.

• Anki Sync Server, the official sync server built into recent versions of Anki. Available as services.anki-sync-server. The pre-existing services.ankisyncd has been marked deprecated and will be dropped after 24.05 due to lack of maintenance of the anki-sync-server softwares.

• Clevis, a pluggable framework for automated decryption, used to unlock encrypted devices in initrd. Available as boot.initrd.clevis.enable.

Backward Incompatibilities

• The power.ups module now generates upsd.conf, upsd.users and upsmon.conf automatically from a set of new configuration options. This breaks compatibility with existing power.ups setups where these files were created manually. Back up these files before upgrading NixOS.

• mkosi was updated to v19. Parts of the user interface have changed. Consult the release notes for a list of changes.

Other Notable Changes

• addDriverRunpath has been added to facilitate the deprecation of the old addOpenGLRunpath setuphook. This change is motivated by the evolution of the setuphook to include all hardware acceleration.

• Cinnamon has been updated to 6.0. Please beware that the Wayland session is still experimental in this release.

• services.postgresql.extraPlugins changed its type from just a list of packages to also a function that returns such a list. For example a config line like services.postgresql.extraPlugins = with pkgs.postgresql_11.pkgs; [ postgis ]; is recommended to be changed to services.postgresql.extraPlugins = ps: with ps; [ postgis ];;

• Programs written in Nim are built with libraries selected by lockfiles. The nimPackages and nim2Packages sets have been removed. See https://nixos.org/manual/nixpkgs/unstable#nim for more information.

• libass now uses the native CoreText backend on Darwin, which may fix subtitle rendering issues with mpv, ffmpeg, etc.

• The Yama LSM is now enabled by default in the kernel, which prevents ptracing non-child processes. This means you will not be able to attach gdb to an existing process, but will need to start that process from gdb (so it is a child). Or you can set boot.kernel.sysctl."kernel.yama.ptrace_scope" to 0.

• Gitea 1.21 upgrade has several breaking changes, including:

  • Custom themes and other assets that were previously stored in custom/public/* now belong in custom/public/assets/*
  • New instances of Gitea using MySQL now ignore the [database].CHARSET config option and always use the utf8mb4 charset, existing instances should migrate via the gitea doctor convert CLI command.

• The hardware.pulseaudio module now sets permission of pulse user home directory to 755 when running in "systemWide" mode. It fixes issue 114399.

• QtMultimedia has changed its default backend to QT_MEDIA_BACKEND=ffmpeg (previously gstreamer on Linux or darwin on MacOS). The previous native backends remain available but are now minimally maintained. Refer to upstream documentation for further details about each platform.
