John Ericson eb7d7780b1 Rename doc/manual{src -> source} 
This is needed to avoid this

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.

    # 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 nixpkgs#glibc^dev

    does already.

  • On Linux, 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 x86_64-linux.

  • You can now disable the global flake registry by setting the flake-registry configuration option to an empty string. The same can be achieved at runtime with --flake-registry "".
