It no longer depends on the ATerm library. + + - Support for configurable parallelism inside builders. Build scripts + have always had the ability to perform multiple build actions in + parallel (for instance, by running `make -j + 2`), but this was not desirable because the number of actions to be + performed in parallel was not configurable. Nix now has an option + `--cores + N` as well as a configuration setting `build-cores = + N` that causes the environment variable NIX\_BUILD\_CORES to be set + to N when the builder is invoked. The builder can use this at its + discretion to perform a parallel build, e.g., by calling `make -j + N`. In Nixpkgs, this can be enabled on a per-package basis by + setting the derivation attribute `enableParallelBuilding` to `true`. + + - `nix-store -q` now supports XML output through the `--xml` flag. + + - Several bug fixes. |
