Backward Incompatibilities

• binwalk was updated to 3.1.0, which has been rewritten in rust. The python module is no longer available. See the release notes of 3.1.0 for more information.

• buildGoPackage has been removed. Use buildGoModule instead. See the Go section in the nixpkgs manual for details.

• strawberry has been updated to 1.2, which drops support for the VLC backend and Qt 5. The strawberry-qt5 package and withGstreamer/withVlc override options have been removed due to this.

• timescaledb requires manual upgrade steps. After you run ALTER EXTENSION, you must run this SQL script. For more details, see the following pull requests #6797. PostgreSQL 13 is no longer supported in TimescaleDB v2.16.

• Support for CUDA 10 has been dropped, as announced in the 24.11 release notes.

• zammad has had its support for MySQL removed, since it was never working correctly and is now deprecated upstream. Check the migration guide for how to convert your database to PostgreSQL.

• nodePackages.insect has been removed, as it's deprecated by upstream. The suggested replacement is numbat.

• nodePackages.webpack-dev-server has been removed, as it should be installed in projects that use it instead.

• The behavior of the networking.nat.externalIP and networking.nat.externalIPv6 options has been changed. networking.nat.forwardPorts now only forwards packets destined for the specified IP addresses.

• nodePackages.meshcommander has been removed, as the package was deprecated by Intel.

• kanata was updated to v1.7.0, which introduces several breaking changes. See the release notes of v1.7.0 for more information.

• vscode-utils.buildVscodeExtension now requires pname as an argument

• nerdfonts has been separated into individual font packages under the namespace nerd-fonts. The directories for font files have changed from $out/share/fonts/{opentype,truetype}/NerdFonts to $out/share/fonts/{opentype,truetype}/NerdFonts/<fontDirName>, where <fontDirName> can be found in the official website as the titles in preview images, with the "Nerd Font" suffix and any whitespaces trimmed.

• retroarch has been refactored and the older retroarch.override { cores = [ ... ]; } to create a RetroArch derivation with custom cores doesn't work anymore, use retroarch.withCores (cores: [ ... ]) instead. If you need more customization (e.g.: custom settings), use wrapRetroArch instead.

• gkraken software and hardware.gkraken.enable option have been removed, use coolercontrol via programs.coolercontrol.enable option instead.

• nodePackages.ganache has been removed, as the package has been deprecated by upstream.

• containerd has been updated to v2, which contains breaking changes. See the containerd 2.0 documentation for more details.

• nodePackages.stackdriver-statsd-backend has been removed, as the StackDriver service has been discontinued by Google, and therefore the package no longer works.

• the notmuch vim plugin now lives in a separate output of the notmuch package. Installing notmuch will not bring the notmuch vim package anymore, add vimPlugins.notmuch-vim to your (Neo)vim configuration if you want the vim plugin.

Other Notable Changes

• Cinnamon has been updated to 6.4.

• bind.cacheNetworks now only controls access for recursive queries, where it previously controlled access for all queries.
