It was +possible for derivations to cause the mode of files outside of the Nix +store to be changed to 444 (read-only but world-readable) by creating +hard links to those files +([details](https://github.com/NixOS/nix/commit/5526a282b5b44e9296e61e07d7d2626a79141ac4)). + +There are also the following improvements: + + - New built-in function: `builtins.hashString`. + + - Build logs are now stored in `/nix/var/log/nix/drvs/XX/`, where *XX* + is the first two characters of the derivation. This is useful on + machines that keep a lot of build logs (such as Hydra servers). + + - The function `corepkgs/fetchurl` can now make the downloaded file + executable. This will allow getting rid of all bootstrap binaries in + the Nixpkgs source tree. + + - Language change: The expression `"${./path} + ..."` now evaluates to a string instead of a path. |
