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 with only 7 packages not currently available, and it should be possible to test this beta without too much trouble. The source code is available at these addresses: [https://github.com/ocaml/ocaml/archive/4.11.0+beta2.tar.gz] [https://caml.inria.fr/pub/distrib/ocaml-4.11/ocaml-4.11.0+beta2.tar.gz] The compiler can also be installed as an OPAM switch with one of the following commands: =E2=94=8C=E2=94=80=E2=94=80=E2=94=80=E2=94=80 =E2=94=82 opam switch create ocaml-variants.4.11.0+beta2 --repositories= =3Ddefault,beta=3Dgit+https://github.com/ocaml/ocaml-beta-repository.git =E2=94=94=E2=94=80=E2=94=80=E2=94=80=E2=94=80 or =E2=94=8C=E2=94=80=E2=94=80=E2=94=80=E2=94=80 =E2=94=82 opam switch create ocaml-variants.4.11.0+beta2+ --repo= sitories=3Ddefault,beta=3Dgit+https://github.com/ocaml/ocaml-beta-repositor= y.git =E2=94=94=E2=94=80=E2=94=80=E2=94=80=E2=94=80 where you replace with one of these: afl, flambda, fp, fp+flambda We would love to hear about any bugs.

This library aims to provide simple to use client library for sending emails over SMTP using _lwt_ for async execution. It is build on top of _mrmime_ and _colombe_. While these libraries are very capable, they aren't that simple to use, _letters_ is trying to fill that gap. Anyway, big thanks for the authors of these projects for doing the heavy lifting. As this library is still in its early stage, I believe I will break the API with first few releases. Luckily the API is quite simple so following these changes should be quite easy. To make this library awesome, any feedback or feature request is welcome. I'll try to address them as quickly as I can. I hope I've managed to scratch someone else's itch too, enjoy.

Previous Week Up Next Week

Hello

Here is the latest OCaml Weekly News, for the week of July 07 to 14, 2020.

OCaml 4.11.0, second beta release

Archive: https://discuss.ocaml.org/t/ocaml-4-11-0-second-beta-release/= 6063/1

octachron announced

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 with only 7 packages not currently available, and it should be possibl= e to test this beta without too much trouble.

The source code is available at these addresses:

http= s://github.com/ocaml/ocaml/archive/4.11.0+beta2.tar.gz
https://caml.inria.fr/pub/distrib/ocaml-4.11/ocaml-4.11.0+beta2.tar= .gz

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=3Ddefault,beta=3Dgit=
+https://github.com/ocaml/ocaml-beta-repository.git

or 

opam switch create ocaml-variants.4.11.0+beta2=
+<VARIANT> --repositories=3Ddefault,b=
eta=3Dgit+https://github.com/ocaml/ocaml-beta-repository.git

where you replace <VARIANT> with one of these: afl, flambda, fp, fp+f= lambda

We would love to hear about any bugs. Please report them here: https://github.com/ocaml= /ocaml/issues

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:

https://github= .com/ocaml/ocaml/blob/4.11/Changes

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

Runtime

  • #9714, #9724: Use the C++ al= ignas keyword when compiling in C++. Fixes a bug with MSVC C++ 2015/2017. A= dd a terminator to the caml_domain_state structure to better e= nsure that members are correctly spaced. (Antonin D=C3=A9cimo, review by Da= vid Allsopp and Xavier Leroy)

Manual and documentation

  • #8644: fix f= ormatting comment about @raise in stdlib's mli files (=C3=89lie Brami, revi= ew by David Allsopp)
  • #9712: Updat= e the version format to allow "". The new format is "major.minor[.pat= chlevel][(+|)additional-info]", for instance "4.12.0~beta1+flambda".= This is a documentation-only change for the 4.11 branch, the new format wi= ll be used starting with the 4.12 branch. (Florian Angeletti, review by Dam= ien Doligez and Xavier Leroy)

letters - simple client abstractions = for sending emails over SMTP

Archive: https://discuss.ocaml.org/= t/ann-letters-simple-client-abstractions-for-sending-emails-over-smtp/6071/= 1

Miko announced

Earlier today I've published the first release of letters. This library aims to provide simple to use client library for sending emails ove= r SMTP using lwt for async execution.

It is build on top of mrmime and colombe. While these libraries are very capable, th= ey aren't that simple to use, letters is trying to fill t= hat gap. Anyway, big thanks for the authors of these projects for doing the heavy lifting.

As this library is still in its early stage, I believe I will break the API= with first few releases. Luckily the API is quite simple so following these changes should be quite = easy.

To make this library awesome, any feedback or feature request is welcome. I= 'll try to address them as quickly as I can.

I hope I've managed to scratch someone else's itch too, enjoy.
