[Nix-dev] nix-exec 2.0.0 released

[Shea Levy]

Hi all,

I'm proud to announce the release of nix-exec 2.0.0. From the release
notes [1]:

* unsafe-perform-io now just takes an IO value directly, instead of
  expecting a function matching the top-level entry point signature
* nix-exec's compile-time settings are now accessible from lib instead
  of as global symbols
* nix-exec's lib now has a fetchgit builtin that caches repositories and
  checkouts. With this, a nix-exec script can now be usefully used
  without even a nixpkgs checkout in the caller's NIX_PATH.

Happy hacking!
