# Release X.Y (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.<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](https://github.com/NixOS/bundlers) 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>`.
