The release of OCaml 5.2.0 is imminent.
As a final step, we are publishing a release candidate to check that everything is in order before the release in the upcoming week(s).
If you find any bugs, please report them on OCaml’s issue tracker.
Compared to the second beta, this release contains one small compiler-libs printer fix and one configuration tweak.
The full change log for OCaml 5.2.0 is available on
GitHub.
A short summary of the changes since the second beta release is also available below.
Installation Instructions
The base compiler can be installed as an opam switch with the following commands on opam 2.1 and later:
opam update
opam switch create 5.2.0~rc1
The source code for the release candidate is also directly available on:
Fine-Tuned Compiler Configuration
If you want to tweak the configuration of the compiler, you can switch to the option variant with:
opam update
opam switch create <switch_name> ocaml-variants.5.2.0~rc1+options <option_list>
where <option_list> is a space-separated list of ocaml-option-* packages. For instance, for a flambda and no-flat-float-array switch:
opam switch create 5.2.0~rc1+flambda+nffa ocaml-variants.5.2.0~rc1+options ocaml-option-flambda ocaml-option-no-flat-float-array
All available options can be listed with opam search ocaml-option.
