Release 2.13 (2023-01-17)
-
The
repeatandenforce-determinismoptions 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^devnow works just as
# nix build nixpkgs#glibc^devdoes already.
-
On Linux,
nix developnow sets the personality for the development shell in the same way as the actual build of the derivation. This makes shells fori686-linuxderivations work correctly onx86_64-linux. -
You can now disable the global flake registry by setting the
flake-registryconfiguration option to an empty string. The same can be achieved at runtime with--flake-registry "".
