**Release Notes**
Please include relevant [release notes](https://github.com/NixOS/nix/blob/master/doc/manual/src/release-notes/rl-next.md) as needed.
**Testing**
If this issue is a regression or something that should block release, please consider including a test either in the [testsuite](https://github.com/NixOS/nix/tree/master/tests) or as a [hydraJob]( https://github.com/NixOS/nix/blob/master/flake.nix#L396) so that it can be part of the [automatic checks](https://hydra.nixos.org/jobset/nix/master).

* Plugins can now register `nix` subcommands.
* The `--indirect` flag to `nix-store --add-root` has become a no-op.
`--add-root` will always generate indirect GC roots from now on.
## Incompatible changes
* The `nix` command is now marked as an experimental feature. This
means that you need to add
> experimental-features = nix-command
```
experimental-features = nix-command
```
to your `nix.conf` if you want to use it, or pass
`--extra-experimental-features nix-command` on the command line.
* The old `nix run` has been renamed to `nix shell` (and there is a
new `nix run` that does something else, as described above).
* The `nix` command no longer has a syntax for referring to packages
in a channel. This means that the following no longer works:
```console
nix build nixpkgs.hello # Nix 2.3
```
Instead, you can either use the `#` syntax to select a package from
a flake, e.g.
```console
nix build nixpkgs#hello
```
Or, if you want to use the `nixpkgs` channel in the `NIX_PATH`
environment variable:
```console
nix build -f '<nixpkgs>' hello
```
* The old `nix run` has been renamed to `nix shell`, while there is a
new `nix run` that runs a default command. So instead of
```console
nix run nixpkgs.hello -c hello # Nix 2.3
```
you should use
```console
nix shell nixpkgs#hello -c hello
```
or just
```console
nix run nixpkgs#hello
```
if the command you want to run has the same name as the package.
* It is now an error to modify the `plugin-files` setting via a
command-line flag that appears after the first non-flag argument to

`waiting for the big garbage collector lock...` is a thing of the
past.
* Binary cache stores now have a setting `compression-level`.
* `nix develop` now has a flag `--unpack` to run `unpackPhase`.
* Lists can now be compared lexicographically using the `<` operator.
* New built-in function: `builtins.groupBy`, with the same functionality as
Nixpkgs' `lib.groupBy`, but faster.

# Release 2.6 (2022-01-24)
* The Nix CLI now searches for a `flake.nix` up until the root of the current
Git repository or a filesystem boundary rather than just in the current
directory.
* The TOML parser used by `builtins.fromTOML` has been replaced by [a
more compliant one](https://github.com/ToruNiina/toml11).
* Added `:st`/`:show-trace` commands to `nix repl`, which are used to
set or toggle display of error traces.
* New builtin function `builtins.zipAttrsWith` with the same
functionality as `lib.zipAttrsWith` from Nixpkgs, but much more
efficient.
* New command `nix store copy-log` to copy build logs from one store
to another.
* The `commit-lockfile-summary` option can be set to a non-empty
string to override the commit summary used when commiting an updated
lockfile. This may be used in conjunction with the `nixConfig`
attribute in `flake.nix` to better conform to repository
conventions.
* `docker run -ti nixos/nix:master` will place you in the Docker
container with the latest version of Nix from the `master` branch.

# 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>`.
