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

Highlights

• The initial work to support native compilation on LoongArch64 has completed, with further changes currently in preparation. In accordance with the Software Development and Build Convention for LoongArch Architectures, this release sets the default march level to la64v1.0, covering the desktop and server processors of 3X5000 and newer series. However, embedded chips without LSX (Loongson SIMD eXtension), such as 2K0300 SoC, are not supported. pkgsCross.loongarch64-linux-embedded can be used to build software and systems for these platforms.

Backward Incompatibilities

• The offrss package was removed due to lack of upstream maintenance since 2012. It's recommended for users to migrate to another RSS reader

• base16-builder node package has been removed due to lack of upstream maintenance.

• gentium package now provides Gentium-*.ttf files, and not GentiumPlus-*.ttf files like before. The font identifiers Gentium Plus* are available in the gentium-plus package, and if you want to use the more recently updated package gentium by sil, you should update your configuration files to use the Gentium font identifier.

• space-orbit package has been removed due to lack of upstream maintenance. Debian upstream stopped tracking it in 2011.

• command-not-found package is now disabled by default; it works only for nix-channels based systems, and requires setup for it to work.

• gnome-keyring no longer ships with an SSH agent anymore because it has been deprecated upstream. You should use gcr_4 instead, which provides the same features. More information on why this was done can be found on the relevant GCR upstream PR.

• lima package now only includes the guest agent for the host's architecture by default. If your guest VM's architecture differs from your Lima host's, you'll need to enable the lima-additional-guestagents package by setting withAdditionalGuestAgents = true when overriding lima with this input.

• telegram-desktop packages now uses Telegram for its binary. The previous name was telegram-desktop. This is due to an upstream decision to make the name consistent with other platforms.

Other Notable Changes

• Added rewriteURL attribute to the nixpkgs config, to allow for rewriting the URLs downloaded by fetchurl.

• New hardening flags, strictflexarrays1 and strictflexarrays3 were made available, corresponding to the gcc/clang options -fstrict-flex-arrays=1 and -fstrict-flex-arrays=3 respectively.

• gramps has been updated to 6.0.0 Upstream recommends backing up your Family Trees before upgrading.
