# Release 2.10 (2022-07-11)
|
|
|
|
* `nix repl` now takes installables on the command line, unifying the usage
|
|
with other commands that use `--file` and `--expr`. Primary breaking change
|
|
is for the common usage of `nix repl '<nixpkgs>'` which can be recovered with
|
|
`nix repl --file '<nixpkgs>'` or `nix repl --expr 'import <nixpkgs>{}'`.
|
|
|
|
This is currently guarded by the `repl-flake` experimental feature.
|
|
|
|
* A new function `builtins.traceVerbose` is available. It is similar
|
|
to `builtins.trace` if the `trace-verbose` setting is set to true,
|
|
and it is a no-op otherwise.
|
|
|
|
* `nix search` has a new flag `--exclude` to filter out packages.
|
|
|
|
* On Linux, if `/nix` doesn't exist and cannot be created and you're
|
|
not running as root, Nix will automatically use
|
|
`~/.local/share/nix/root` as a chroot store. This enables non-root
|
|
users to download the statically linked Nix binary and have it work
|
|
out of the box, e.g.
|
|
|
|
```
|
|
# ~/nix run nixpkgs#hello
|
|
warning: '/nix' does not exists, so Nix will use '/home/ubuntu/.local/share/nix/root' as a chroot store
|
|
Hello, world!
|
|
```
|
|
|
|
* `flake-registry.json` is now fetched from `channels.nixos.org`.
|
|
|
|
* Nix can now be built with LTO by passing `--enable-lto` to `configure`.
|
|
LTO is currently only supported when building with GCC.
