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.
- The official Nix formatter `nixfmt` is now stable and available as `pkgs.nixfmt`, deprecating the temporary `pkgs.nixfmt-rfc-style` attribute. The classic `nixfmt` will stay available for some more time as `pkgs.nixfmt-classic`.
