Nix 2.7.0 released

We’re pleased to announce the availability of Nix 2.7.0. It will be available from NixOS - Getting Nix / NixOS.

Here are the release notes:

  • Nix will now make some helpful suggestions when you mistype something on the command line. For instance, if you type nix build nixpkgs#thunderbrd, it will suggest thunderbird.

  • A number of “default” flake output attributes have been renamed. These are:

    • defaultPackage.<system> → packages.<system>.default
    • defaultApps.<system> → apps.<system>.default
    • defaultTemplate → templates.default
    • defaultBundler.<system> → bundlers.<system>.default
    • overlay → overlays.default
    • devShell.<system> → devShells.<system>.default

    The old flake output attributes still work, but nix flake check will warn about them.

  • Breaking API change: nix bundle now supports bundlers of the form bundler.<system>.<name>= derivation: another-derivation;. This supports additional functionality to inspect evaluation information during bundling. A new repository 73 has various bundlers implemented.

  • nix store ping now reports the version of the remote Nix daemon.

  • nix flake {init,new} now display information about which files have been created.

  • Templates can now define a welcomeText attribute, which is printed out by nix flake {init,new} --template <template>.

The next release 149 is scheduled for . The next release is scheduled for 2022-04-18.
