Release 0.16 (August 16, 2010) + +This release has the following improvements: + + + + + The Nix expression evaluator is now much faster in most + cases: typically, 3 + to 8 times compared to the old implementation. It also + uses less memory. 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 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 + enableParallelBuilding to + true. + + + + + nix-store -q now supports XML output + through the flag. + + + + Several bug fixes. + + + + +
