[https://bucklescript.github.io/blog/2019/08/12/release-5-10-0]One feature that might interest you is that we support NODE_PATH in dependency resolving so that in theory you can use opam to install
bucklescript packages, the directory layout is no longer tied to `node_modules' x509 0.7 released ═════════════════Archive: [https://discuss.ocaml.org/t/ann-x509-0-7-released/4252/1]
Hannes Mehnert announced ────────────────────────it is my pleasure to announce the x509 0.7 series, which contains a
major revision of the API (using a map instead of lists forextensions, general and distinguished names, …). The release 0.7.1 is already merged into the opam-repository, and users of x509 have been updated to comply with the new API. I wrote a blog post about this release – [https://hannes.nqsb.io/Posts/X50907]. I'm happy to receive
feedback, either in this topic, via eMail, or via social media.A(nother) short tutorial on how to use Dune to build and use Opam packages
══════════════════════════════════════════════════════════════════════════ Archive: [https://sympa.inria.fr/sympa/arc/caml-list/2019-08/msg00046.html] Jocelyn Sérot announced ─────────────────────── In the continuation of my last announcement, here’s another pagecontaining a collection of simple projects showing how to use Dune for
building and using Opam packages : [https://github.com/jserot/dune-howto] In the hope this can be useful to anyone starting to use these powerful tools.Again, comments, bug reports and suggestions for improvements welcome.
No debugger improvements in 4.08? ═════════════════════════════════ Archive: [https://discuss.ocaml.org/t/no-debugger-improvements-in-4-08/3158/7] Continuing this thread, gasche announced ────────────────────────────────────────On the "good news" side, we were finally able to review and merge
support for dynlinked code in ocamldebug (in trunk, not 4.08;[https://github.com/ocaml/ocaml/pull/8654]), which could be a big help for people using ocamldebug with plugins – some Coq hackers do this,
for example. The end of Camlp4 ═════════════════ Archive: [https://discuss.ocaml.org/t/the-end-of-camlp4/4216/89] Deep in this thread, Anton Kochkov said ───────────────────────────────────────I think that everyone can just provide their suggestions about ppx here: [https://discuss.ocaml.org/t/the-future-of-ppx/3766], which is a
proper place for discussing the future of this subsystem. Anton Kochkov then added ──────────────────────── I also cleaned up the list in [https://discuss.ocaml.org/t/the-end-of-camlp4/4216/2], removedobsolete projects and these that were fixed since already. Many of
them also dropped the camlp4 dependency, but not made releaseyet. Added the issues links to those that are at GitHub, for tracking
the progress. release of batteries v2.10.0 ════════════════════════════ Archive: [https://discuss.ocaml.org/t/ann-release-of-batteries-v2-10-0/4261/1] UnixJunkie announced ────────────────────OCaml batteries included is a community maintained extension of the
OCaml standard library.The batteries maintainers are pleased to announce the latest release:
v2.10.0. This minor release adds support for OCaml 4.08.0.Bug reports, pull requests and user feedback are warmly welcome, see
the project page at [https://github.com/ocaml-batteries-team/batteries-included/] The library's API documentation can be found at: [http://ocaml-batteries-team.github.io/batteries-included/hdoc2/]After an `opam update' your should be able to do an `opam upgrade
batteries' an enjoy this new release.This release is compatible with OCaml 4.08.0, but it is not complete with respect to the standard library of OCaml 4.08.0: this release saw a lot of changes to the standard library, which have not yet been made available in the corresponding Batteries module. This means that users
of OCaml 4.08.0 (and Batteries 2.10.0) will have access to thesefunctions, but users of older OCaml versions (and Batteries 2.10.0) will not. If you are looking for this kind of backward-compatibility
of new functions, as provided by previous Batteries releases, we recommend trying the `stdcompat' library. Change log entries:• added LazyList.equal: `('a -> 'b -> bool) -> 'a t -> 'b t -> bool'
#811 (Marshall Abrams, review by Gabriel Scherer)• added BatList.fold_while : `('acc -> 'a -> bool) -> ('acc -> 'a -> 'acc) -> 'acc -> 'a list -> 'acc * 'a list' #889 (Francois Berenger,
Thibault Suzanne)• fix `BatNum.of_float_string' on inputs between -1 and 0: "-0.5" or "-.5" would be interpreted as "0.5" or ".5". #886, #887 (Gabriel
Scherer, report by Marcel Hark)• added BatHashtbl.merge and merge_all #891 (Cedric Cellier, Francois
Berenger, Gabriel Scherer) Down 0.0.1 ══════════ Archive: [https://discuss.ocaml.org/t/ann-down-0-0-1/4140/13] Daniel Bünzli announced ───────────────────────v0.0.2 has just been published which has a few small adjustements. See
the [release notes]. [release notes] https://github.com/dbuenzli/down/blob/master/CHANGES.md#v002-2019-08-15-zagreb Getting Started in OCaml Notes ══════════════════════════════ Archive: [https://discuss.ocaml.org/t/getting-started-in-ocaml-notes/4265/1] Philip Zucker asked ───────────────────Hi! I've been getting going in OCaml over the last couple weeks and
wrote down my very [basic notes], more about the ecosystem andlearning resources than the language itself. It might seem obvious
once you're deep in OCaml, but it actually was kind of confusingfiguring out even the simplest lay of the land. This is kind of a silly soft question, but any suggestions for other tools, libraries,
learning resources, things that would be nice to know about? [basic notes] http://www.philipzucker.com/notes-on-getting-started-in-ocaml/ Yotam Barnoy suggested ──────────────────────Have you found [Ocamlverse]? We'd also love to have contributions.
