opam 2.0.1 is out!
We are pleased to announce the release of opam 2.0.1.
This new version contains mainly backported fixes, some platform-specific:
- Cold boot for MacOS/CentOS/Alpine
- Install checksum validation on MacOS
- Archive extraction for OpenBSD now defaults to using
gtar
- Fix compilation of mccs on MacOS and Nix platforms
- Do not use GNU-sed specific features in the release Makefile, to fix build on OpenBSD/FreeBSD
- Cleaning to enable reproducible builds
- Update configure scripts
And some opam specific:
- git: fix git fetch by sha1 for git < 2.14
- linting: add
test
variable warning and empty description error - upgrade: convert pinned but not installed opam files
- error reporting: more comprehensible error message for tar extraction, and upgrade of git-url compilers
- opam show: upgrade given local files
- list: as opam 2.0.0
list
doesn't return non-zero code if list is empty, add--silent
option for a silent output and returns 1 if list is empty
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.
- 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)
- From source, manually: see the instructions in the README.
We hope you enjoy this new major 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 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. Please reach out, we'll be delighted to discuss your challenges: contact@ocamlpro.com or book a quick discussion.
