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 boot.readOnlyNixStore has been removed. Control over bind mount options on /nix/store is now offered by the boot.nixStoreMountOpts option.
