OPAM 1.1.1 released
On , by Louis Gesbert

We are proud to announce that OPAM 1.1.1 has just been released.

This minor release features mostly stability and UI/doc improvements over OPAM 1.1.0, but also focuses on improving the API and tools to be a better base for the platform (functions for opam-doc, interface with tools like opamfu and opam-installer). Lots of bigger changes are in the works, and will be merged progressively after this release.

Installing

Installation instructions are available on the wiki.

Note that some packages may take a few days until they get out of the pipeline. If you're eager to get 1.1.1, either use our binary installer or compile from source.

The 'official' package repository is now hosted at opam.ocaml.org, synchronised with the Git repository at http://github.com/ocaml/opam-repository, where you can contribute new packages descriptions. Those are under a CC0 license, a.k.a. public domain, to ensure they will always belong to the community.

Thanks to all of you who have helped build this repository and made OPAM such a success.
