I’m pleased to announce the availability of Nix 2.13.0. It will be available from Download Nix / NixOS | Nix & NixOS and http://releases.nixos.org/?prefix=nix/nix-2.13.0/.
Here are the release notes:
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.
# 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 is now used consistently. Historical release notes were not changed.
Error traces have been reworked to provide detailed explanations and more accurate error locations. A short excerpt of the trace is now shown by default when an error occurs.
Allow explicitly selecting outputs in a store derivation installable, just like we can do with other sorts of installables. For example,
# nix-build /nix/store/gzaflydcr6sb3567hap9q6srzx8ggdgg-glibc-2.33-78.drv^dev
now works just as
# nix-build glibc^dev
nix develop now sets the personality 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
Unfortunately, this release has a serious regression in the evaluator. We’ll follow it up with a point release.
Cause of the regression ^
Is it now also possible to disable the global registry by setting
flake-registry to empty (#5420).
For example using the cli:
nix --flake-registry "" registry list
will show you only your user entries.
With “flake capabilites” leaking into regular old-style expressions as well, can’t we make the experimental feature
flakes available without also having to enable
I do not really see a reason for
nix-command being enabled for
nix-build -I nixpkgs=github:nixos/nixpkgs/nixos-unstable '<nixpkgs>' -A hello or
builtins.getFlake being used in a regular “old school”
I made a 2.13.1 release that fixes this and a few smaller regressions.
This does not require the
nix-command feature. For instance,
nix-build --experimental-features 'flakes' -I nixpkgs=github:nixos/nixpkgs/nixos-unstable '<nixpkgs>' -A hello works.
Did something break?

@nrdxp Looks like it. Can you make an issue for that?
