opam 2.0.0 Release Candidate 3 is out!
We are pleased to announce the release of a third release candidate for opam 2.0.0. This one is expected to be the last before 2.0.0 comes out.
Changes since the 2.0.0~rc2 are, as expected, mostly fixes. We deemed it useful, however, to bring in the following:
- a new command
opam switch linkthat allows to select a switch to be used in a given directory (particularly convenient if you use the shell hook for automatic opam environment update)
- a new option
opam install --assume-built, that allows to install a package using its normal opam procedure, but for a source repository that has been built by hand. This fills a gap that remained in the local development workflows.
The preview of the opam 2 webpages can be browsed at http://opam.ocaml.org/2.0-preview/ (please report issues here).
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.
Thanks a lot for testing out this new RC and reporting any issues you may find.
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: email@example.com.
