opam 2.0.0 Release Candidate 1 is out! On 2018-02-02 , by Louis Gesbert

We are pleased to announce a first release candidate for the long-awaited opam 2.0.0.

A lot of polishing has been done since the last beta, including tweaks to the built-in solver, allowing in-source package definitions to be gathered in an opam/ directory, and much more.

With all of the 2.0.0 features getting pretty solid, we are now focusing on bringing all the guides up-to-date¹, updating the tools and infrastructure, making sure there are no usability issues with the new workflows, and being future-proof so that further updates break as little as possible.

You are invited to read the beta5 announcement for details on the 2.0.0 features. Installation instructions haven't changed:

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. From source, using opam: opam update; opam install opam-devel (then copy the opam binary to your PATH as explained) From source, manually: see the instructions in the README.

Thanks a lot for testing out the RC and reporting any issues you may find. See what we need tested for more detail.

You can at the moment rely on the manpages , the Manual , and of course the API , but other pages might be outdated.
