Dear OCaml users,
The release of OCaml version 4.11.0 is imminent. We have created a release candidate that you can test.
For users of the beta releases, this release candidate is exactly the same as the last beta release except for a minor fix for the
#show directive in the toplevel.
The compiler can be installed as an OPAM switch with the following commands:
$ opam update $ opam switch create 4.11.0+rc2 --repositories=default,beta=git://github.com/ocaml/ocaml-beta-repository.git
— The opam ecosystem —
The opam ecosystem is in good shape for this release candidate.
For maximum compatibility, you can use the following opam-alpha-repository:
$ opam repo add alpha https://github.com/kit-ty-kate/opam-alpha-repository.git
during your tests. This repository integrate not-yet-upstreamed or unreleased fixes to various packages.
With this repository all except a handful of packages are compatible with this release candidate.
All core tools (see meta issue) – including Merlin – work, except for ocaml-lsp-server (which is not officially released yet and only relevant for Windows users).
All packages except 7 over the 2134 available packages in opam-repository that were compatible with OCaml 4.10 are also compatible with OCaml 4.11.
— Call to testers —
Given that the release is very close and the state of the community packages stable enough, we would like to encourage people to give it a try before the release, especially for those on non-x86_64 architectures. I’ve personally been using OCaml 4.11 almost exclusively for the past 3 months and did not really encountered any issues on my x86_64 machine with a fairly regular setup.
Give it a try! Happy testing!
