Hello

Here is the latest OCaml Weekly News, for the week of September 21 to 28, 2= 021.

Brr 0.0.2, a toolkit for programming browsers

Archive: https://discuss.ocaml.org/t/ann-brr-0-0-2-a-t= oolkit-for-programming-browsers/8521/1

Daniel B=C3=BCnzli announced

It's my pleasure to announce the release 0.0.2 of Brr, a toolkit for programming browsers in OCaml with the js_of_ocaml compiler.

Once it has made it to the repo, install with opam install brr= and consult the API doc= s and manuals (or via odig doc brr).

This release fixes binding bugs, adds a few new bindings and tweaks some ex= isting signatures. Thanks to all of those who provided bug reports, suggestions and code.

The release notes have all the details.

Become an Outreachy Mentor: support the growth and diversity o= f the OCaml community

Archive: https://di= scuss.ocaml.org/t/become-an-outreachy-mentor-support-the-growth-and-diversi= ty-of-the-ocaml-community/8213/13

Thibaut Mattio announced

I've submitted two projects for the winter session:

  • Integrate a package health check in ocaml.org

To essentially integrate a version of check.ocamllabs.io that can be used b= y opam-repository maintainers and opam users into the next version of ocaml.org (= https://v3.ocaml.org).

  • Support .eml files in OCaml's VSCode extension

To add support for Dream's .eml files syntax in the extension, and eventually have error reporting for these files from OCa= ml LSP Server.

I'm more than interested in having co-mentors for these two projects, so if= you wanted to mentor Outreachy interns but didn't have any project ideas, don't hesitate to reach out :slight_smil= e:

Another way to help that does not involve mentoring is to find good first i= ssues that will help onboard and select candidates for the projects. Any help on this effort to identify, create an= d document good first issues for the different projects is more than welcome!

OCaml 4.13.0 (and 4.12.1)

Archive: https://discuss.ocaml.org/t/ocaml-4-13-0-and-4-12-1/8529/1

octachron announced

The OCaml team ha the pleasure of celebrating the 175th anniversary of the = discovery of Neptune by announcing the joint releases of OCaml version 4.13.0 and 4.12.1 .

Some of the highlights in the 4.13.0 release are:

  • Safe points: a multicore prerequisite that ensures that ocamlopt-genera= ted code can always be interrupted.
  • The best-fit GC allocation policy is now the default policy (and many o= ther GC improvements).
  • Named existential type variables in pattern matching: Showable (t= ype a) (x, show : a * (a -> string)).
  • Improved error messages for functor application and functor types.
  • Let-punning for monadic let: let* x =3D x in can be shorte= ned to let* x in.
  • Module type substitutions: SIG with module type T =3D F(X).S.
  • Many other quality of life improvements
  • Many bug fixes

The 4.12.1 release is a collection of safe bug fixes, cherry-picked from th= e 4.13.0 development cycle. If you were using OCaml 4.12.0 and cannot yet upgrade to 4.13.0, thi= s release is for you.

The full list of changes can be found in the changelogs below. (Editor n= ote: as it=E2=80=99s quite long, it is not included here. Please follow= the link to the original article to read it.)

Those releases are available as OPAM switches, and as a source download her= e:
