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.

Support for CUDA 10 has been dropped, as announced in the 24.11 release notes.
