# Release 2.13 (2023-01-17)
|
|
|
|
|
|
|
|
|
|
* The `repeat` and `enforce-determinism` options have been removed
|
|
|
|
|
since they had been broken under many circumstances for a long time.
|
|
|
|
|
|
|
|
|
|
* You can now use [flake references] in the [old command line interface], e.g.
|
|
|
|
|
|
|
|
|
|
[flake references]: ../command-ref/new-cli/nix3-flake.md#flake-references
|
|
|
|
|
[old command line interface]: ../command-ref/main-commands.md
|
|
|
|
|
|
|
|
|
|
```shell-session
|
|
|
|
|
# nix-build flake:nixpkgs -A hello
|
|
|
|
|
# nix-build -I nixpkgs=flake:github:NixOS/nixpkgs/nixos-22.05 \
|
|
|
|
|
'<nixpkgs>' -A hello
|
|
|
|
|
# NIX_PATH=nixpkgs=flake:nixpkgs nix-build '<nixpkgs>' -A hello
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
* Instead of "antiquotation", the more common term [string interpolation](../language/string-interpolation.md) is now used consistently.
|
|
|
|
|
Historical release notes were not changed.
|
|
|
|
|
|
|
|
|
|
* Allow explicitly selecting outputs in a store derivation installable, just like we can do with other sorts of installables.
|
|
|
|
|
For example,
|
|
|
|
|
```shell-session
|
2023-01-17 11:03:30 -05:00
|
|
|
# nix-build /nix/store/gzaflydcr6sb3567hap9q6srzx8ggdgg-glibc-2.33-78.drv^dev
|
2023-01-17 07:23:31 -05:00
|
|
|
```
|
|
|
|
|
now works just as
|
|
|
|
|
```shell-session
|
2023-01-17 11:03:30 -05:00
|
|
|
# nix-build glibc^dev
|
2023-01-17 07:23:31 -05:00
|
|
|
```
|
|
|
|
|
does already.
|
|
|
|
|
|
|
|
|
|
* On Linux, `nix develop` now sets the
|
|
|
|
|
[*personality*](https://man7.org/linux/man-pages/man2/personality.2.html)
|
|
|
|
|
for the development shell in the same way as the actual build of the
|
|
|
|
|
derivation. This makes shells for `i686-linux` derivations work
|
|
|
|
|
correctly on `x86_64-linux`.
