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
files, use 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/*).

Install
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:
https://github.com/ocaml/opam/releases/tag/2.1.0
Upgrade
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
running opam update
. If you want to use the auto-setup feature, remove the
"eval opam config env
line you have previously added in your ~/.profile
and run 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.

About OCamlPro:
OCamlPro is a R&D lab founded in 2011, with the mission to help industrial users benefit from experts with a state-of-the-art knowledge of programming languages theory and practice.
- We provide audit, support, custom developer tools and training for both the most modern languages, such as Rust, Wasm and OCaml, and for legacy languages, such as COBOL or even home-made domain-specific languages;
- We design, create and implement software with great added-value for our clients. High complexity is not a problem for our PhD-level experts. For example, we helped the French Income Tax Administration re-adapt and improve their internally kept M language, we designed a DSL to model and express revenue streams in the Cinema Industry, codename Niagara, and we also developed the prototype of the Tezos proof-of-stake blockchain from 2014 to 2018.
- We have a long history of creating open-source projects, such as the Opam package manager, the LearnOCaml web platform, and contributing to other ones, such as the Flambda optimizing compiler, or the GnuCOBOL compiler.
- We are also experts of Formal Methods, developing tools such as our SMT Solver Alt-Ergo (check our Alt-Ergo Users' Club) and using them to prove safety or security properties of programs.
Please reach out, we'll be delighted to discuss your challenges: contact@ocamlpro.com or book a quick discussion.
