opam 2.0.5 release
We are pleased to announce the minor release of opam 2.0.5.
This new version contains build update and small fixes:
- Bump src_ext Dune to 1.6.3, allows compilation with OCaml 4.08.0. [#3887 @dra27]
- Support Dune 1.7.0 and later [#3888 @dra27 - fix #3870]
- Bump the ocaml_mccs lib-ext, to include latest changes [#3896 @AltGr]
- Fix cppo detection in configure [#3917 @dra27]
- Read jobs variable from OpamStateConfig [#3916 @dra27]
- Linting:
- Fix typos [#3891 @dra27, @mehdid]
Note: To homogenise macOS name on system detection, we decided to keep
macos
, and convertdarwin
tomacos
in opam. For the moment, to not break jobs & CIs, we keep uploadingdarwin
&macos
binaries, but from the 2.1.0 release, onlymacos
ones will be kept.
Installation instructions (unchanged):
- From binaries: run
sh <(curl -sL https://raw.githubusercontent.com/ocaml/opam/master/shell/install.sh)
or download manually from the Github "Releases" page to your PATH. In this case, don't forget to run opam init --reinit -ni
to enable sandboxing if you had version 2.0.0~rc manually installed or to update you sandbox script.
- From source, using opam:
opam update; opam install opam-devel
(then copy the opam binary to your PATH as explained, and don't forget to run opam init --reinit -ni
to enable sandboxing if you had version 2.0.0~rc manually installed or to update you sandbox script)
- From source, manually: see the instructions in the README.
We hope you enjoy this new minor version, and remain open to bug reports and suggestions.

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.
