Subject: [Caml-list] OCaml 4.11.0, second beta release
Date: Mon, 6 Jul 2020 23:05:36 +0200
Message-ID: <> (raw)

Dear OCaml users,

The release of OCaml 4.11.0 is approaching.
As one step further in this direction, we have published a second beta
release. This new release fixes an MSVC-specific runtime issue.

The compatibility of the opam ecosystem with OCaml 4.11.0 is currently quite
good, and it should be possible to test this beta without too much trouble.

The source code is available at these addresses:

The compiler can also be installed as an OPAM switch with one of the
following commands:

opam switch create ocaml-variants.4.11.0+beta2 --repositories=default,beta=git+


opam switch create ocaml-variants.4.11.0+beta2+<VARIANT> --repositories=default,beta=git+

 where you replace <VARIANT> with one of these:

We would love to hear about any bugs. Please report them here:

If you are interested by the list of new features, and the on-going list
of bug fixes the
updated change log for OCaml 4.11.0 is available at:

Compared to the previous beta release, the exhaustive list of changes
is as follows:


- #9714, #9724: Use the C++ alignas keyword when compiling in C++.
   Fixes a bug with MSVC C++ 2015/2017. Add a terminator to the
   `caml_domain_state` structure to better ensure that members are
   correctly spaced.
   (Antonin Décimo, review by David Allsopp and Xavier Leroy)

Manual and documentation

- #8644: fix formatting comment about @raise in stdlib's mli files
   (Élie Brami, review by David Allsopp)

- #9712: Update the version format to allow "~".
   The new format is "major.minor[.patchlevel][(+|~)additional-info]",
   for instance "4.12.0~beta1+flambda".
   This is a documentation-only change for the 4.11 branch, the new format
   will be used starting with the 4.12 branch.
   (Florian Angeletti, review by Damien Doligez and Xavier Leroy)

Happy hacking,

-- Florian Angeletti and Sébastien Hinderer for the OCaml team.
