Re: [Caml-list] [ANN] final release of OPAM 1.1.0

[Anil Madhavapeddy <anil@recoil.org>]

It probably should have been 2.0.0, but it was too late in the release
cycle before we gave up on 1.0 compatibility.  Upgrades never work for
the first release anyway :-)

Thanks for the Nix package, I'm looking forward to trying it out!
(and a belated thank you to Mehdi Dogguy for upload OPAM 1.1 to Debian
testing as well).
