OPAM 1.0.0 released
I am very happy to announce the first official release of OPAM!
Many of you already know and use OPAM so I won't be long. Please read beta-release-of-opam for a longer description.
1.0.0 fixes many bugs and add few new features to the previously announced beta-release.
The most visible new feature, which should be useful for beginners with
OCaml and OPAM, is an auto-configuration tool. This tool easily enables all
the features of OPAM (auto-completion, fix the loading of scripts for the
toplevel, opam-switch-eval alias, etc). This tool runs interactively on each
opam init invocation. If you don't like OPAM to change your configuration
opam init --no-setup. If you trust the tool blindly, use
opam init --auto-setup. You can later review the setup by doing
opam config setup --list and call the tool again using
opam config setup
(and you can of course manually edit your ~/.profile (or ~/.zshrc for zsh
users), ~/.ocamlinit and ~/.opam/opam-init/*).
- Bug reports and feature requests for the OPAM tool:
- Packaging issues or requests for a new packages:

Packages for Debian and OSX (at least homebrew) should follow shortly and I'm looking for volunteers to create and maintain rpm packages. The binary installer is up-to-date for Linux and Darwin 64-bit architectures, the 32-bit version for Linux should arrive shortly.
If you want to build from sources, the full archive (including dependencies) is available here:
If you are upgrading from 0.9.* you won't have anything special to do apart
installing the new binary. You can then update your package metadata by
opam update. If you want to use the auto-setup feature, remove the
opam config env line you have previously added in your ~/.profile
opam config setup --all.
So everything should be fine. But you never know ... so if something goes horribly wrong in the upgrade process (of if your are upgrading from an old version of OPAM) you can still trash your ~/.opam, manually remove what OPAM added in your ~/.profile (~/.zshrc for zsh users) and ~/.ocamlinit, and start again from scratch.
Great success on github. Thanks everybody for the great contributions!

Au sujet d'OCamlPro:
OCamlPro is a R&D lab founded in 2011, with the mission to help industrial users benefit from state-of-the art programming languages like OCaml and Rust.
We design, create and implement custom ad-hoc software for our clients. We also have a long experience in developing and maintaining open-source tooling for OCaml, such as Opam, TryOCaml, ocp-indent, ocp-index and ocp-browser, and we contribute to the core-development of OCaml, notably with our work on the Flambda optimizer branch.
Another area of expertise is that of Formal Methods, with tools such as our SMT Solver Alt-Ergo (check our Alt-Ergo Users'). We also provide vocational trainings in OCaml and Rust, and we can build courses on formal methods on-demand. Do not hesitate to reach out by email: firstname.lastname@example.org.
