Release 25.05 (“Warbler”, 2025.05/??)

Highlights

• This release of Nixpkgs requires macOS Big Sur 11.3 or newer, as announced in the 24.11 release notes. We cannot guarantee that packages will continue to work on older versions of macOS. Future Nixpkgs releases will only support macOS versions supported by Apple; this means that Nixpkgs 25.11 will require macOS Sonoma 14 or newer. Users on old macOS versions should consider upgrading to a supported version (potentially using OpenCore Legacy Patcher for old hardware) or installing NixOS. If neither of those options are viable and you require new versions of software, MacPorts supports versions back to Mac OS X Snow Leopard 10.6.

• GCC has been updated from GCC 13 to GCC 14. This introduces some backwards‐incompatible changes; see the upstream porting guide for details.

• LLVM has been updated from LLVM 16 (on Darwin) and LLVM 18 (on other platforms) to LLVM 19. This introduces some backwards‐incompatible changes; see the upstream release notes for details.

• The default PHP version has been updated to 8.3.

New Modules

• Kimai, a web-based multi-user time-tracking application. Available as services.kimai.

• Omnom, a webpage bookmarking and snapshotting service. Available as services.omnom.

• Amazon CloudWatch Agent, the official telemetry collector for AWS CloudWatch and AWS X-Ray. Available as services.amazon-cloudwatch-agent.

• agorakit, an organization tool for citizens' collectives. Available with services.agorakit.

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.

• 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.

• 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.

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

• 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.
