Release 2.7 (2022-03-07)

• 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. → packages..default
  • defaultApps. → apps..default
  • defaultTemplate → templates.default
  • defaultBundler. → bundlers..default
  • overlay → overlays.default
  • devShell. → devShells..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..<name>= derivation: another-derivation;. This supports additional functionality to inspect evaluation information during bundling. A new repository 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>.
