- Now fetching nixpgks with fetchFromGitHub by computing and saving the sha256 at update time - Detecting core GHC libraries and setting them to null to fix builds, workaround for https://github.com/input-output-hk/stack2nix/issues/134 - Add override directory to fix builds for specific ghc versions - Speed up builds by disabling library profiling for everything - New nix file structure with powerful selection mechanisms
