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.

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.

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

neovim: Added support for the vim.o.exrc option, the VIMINIT environment variable, and sourcing of sysinit.vim.

See the neovim help page :help startup for more information, as well as the nixpkgs neovim wrapper documentation.
