More than two years since the last major release, Nix 2.4 is nearly upon us. It has a lot of changes, which you can find in the release notes. I would like to ask everybody who hasn’t followed nix-unstable to try out the 2.4 release candidate, which is available here: https://releases.nixos.org/?prefix=nix/nix-2.4pre-rc1 (sorry for the broken directory listing).
You can install it on non-NixOS systems by running:
# curl -L https://releases.nixos.org/nix/nix-2.4pre-rc1/install | sh
If you already have Nix installed and are on x86_64-linux, you can try it out by getting it from the binary cache:
# nix-shell -p 'builtins.storePath /nix/store/f6iisy5i007yxaygdxg0pwdbpvpn794i-nix-2.4pre-rc1' # nix --version nix (Nix) 2.4pre-rc1
Or if you’re already have a Nix version that supports flakes, you can get 2.4pre-rc1 in a shell:
# nix shell nix/2.4pre-rc1 # nix --version nix (Nix) 2.4pre-rc1
Please report any and all issues in the bug tracker.
