Release 2.1 (2018-09-02)

This is primarily a bug fix release. It also reduces memory consumption in certain situations. In addition, it has the following new features:

  • The Nix installer will no longer default to the Multi-User installation for macOS. You can still instruct the installer to run in multi-user mode.

  • The Nix installer now supports performing a Multi-User installation for Linux computers which are running systemd. You can select a Multi-User installation by passing the --daemon flag to the installer: sh <(curl -L https://nixos.org/nix/install) --daemon.

    The multi-user installer cannot handle systems with SELinux. If your system has SELinux enabled, you can force the installer to run in single-user mode.

  • New builtin functions: builtins.bitAnd, builtins.bitOr, builtins.bitXor, builtins.fromTOML, builtins.concatMap, builtins.mapAttrs.

  • The S3 binary cache store now supports uploading NARs larger than 5 GiB.

  • The S3 binary cache store now supports uploading to S3-compatible services with the endpoint option.

  • The flag --fallback is no longer required to recover from disappeared NARs in binary caches.

  • nix-daemon now respects --store.

  • nix run now respects nix-support/propagated-user-env-packages.
