# Release X.Y (202?-??-??)
* Nix now provides better integration with zsh's run-help feature. It is now
included in the Nix installation in the form of an autoloadable shell
function, run-help-nix. It picks up Nix subcommands from the currently typed
in command and directs the user to the associated man pages.
* `nix repl` has a new build-'n-link (`:bl`) command that builds a derivation
while creating GC root symlinks.
* The path produced by `builtins.toFile` is now allowed to be imported or read
even with restricted evaluation. Note that this will not work with a
read-only store.
* `nix build` has a new `--print-out-paths` flag to print the resulting output paths.
This matches the default behaviour of `nix-build`.
* You can now specify which outputs of a derivation `nix` should
operate on using the syntax `installable^outputs`,
e.g. `nixpkgs#glibc^dev,static` or `nixpkgs#glibc^*`. By default,
`nix` will use the outputs specified by the derivation's
`meta.outputsToInstall` attribute if it exists, or all outputs
otherwise.
Selecting derivation outputs using the attribute selection syntax
(e.g. `nixpkgs#glibc.dev`) no longer works.
* Running nix with the new `--debugger` flag will cause it to start a repl session if
there is an exception thrown during eval, or if `builtins.break` is called. From
there one can inspect symbol values and evaluate nix expressions. In debug mode
the following new repl commands are available:
```
:env Show env stack
:bt Show trace stack
:st Show current trace
:st <idx> Change to another trace in the stack
:c Go until end of program, exception, or builtins.break().
:s Go one step
```
* `builtins.fetchTree` (and flake inputs) can now be used to fetch plain files
over the `http(s)` and `file` protocols in addition to directory tarballs.
