capnp-rpc 0.4.0
═══════════════

  <https://discuss.ocaml.org/t/ann-capnp-rpc-0-4-0/4524/1>


Thomas Leonard announced
────────────────────────

  I'm pleased to announce the release of [capnp-rpc 0.4.0], an 
  OCaml
  implementation of the Cap'n Proto RPC specification.

  If you haven't used the library before, please see the 
  [documentation
  and tutorial]. Cap'n Proto RPC aims to provide secure, 
  efficient,
  typed communications between multiple parties.

  This library is now being used to build [ocaml-ci], where it is 
  used
  for all communication between the web frontend and backend 
  services,
  and to provide a command-line client.


[capnp-rpc 0.4.0]
<https://github.com/mirage/capnp-rpc/releases/tag/v0.4.0>

[documentation and tutorial]
<https://github.com/mirage/capnp-rpc/blob/master/README.md>

[ocaml-ci] <https://github.com/ocaml-ci/ocaml-ci>

Main changes since v0.3
╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌

  Breaking changes:

  • Wrap errors with the ``Capnp' tag to make it easier to compose 
  with
    other types of error.

  • Prefix all command-line options with `capnp-'.
    e.g. `--listen-address' is now `--capnp-listen-address'.  The 
    old
    names were confusing for applications that supported other 
    protocols
    too (e.g. a web server).

  New features:

  • Add `Capability.with_ref' convenience function.  This 
  automatically
    calls `dec_ref' when done.

  • Add Unix `Cap_file' module to load and save `Sturdy_refs'.  In
    particular, this ensures that saved cap files get a mode of 
    `0o600',
    since they contain secrets.

  • Export cmdliner network address parsing.  This is useful if 
  you
    don't want to use the default option parsing.  For example, if 
    you
    want to make Cap'n Proto an optional feature of your program.

  • Upgrade from `uint' (which is deprecated) to the newer 
  `stdint'.
    The latest version of `uint' is just a wrapper around 
    `stdint', so
    this shouldn't break anything if you are using the latest 
    version.

  • Put cmdliner options in their own man-page section.  Use
    `Capnp_rpc_unix.manpage_capnp_options' to control where in 
    your
    man-page they appear.

  • Enable `SO_KEEPALIVE' for TCP connections.  For use with 
  Docker's
    libnetwork, try something like this in your `stack.yml':
    ┌────
    │ sysctls:
    │   - 'net.ipv4.tcp_keepalive_time=60'

Ocaml-protoc.plugin.1.0.0
═════════════════════════

  <https://discuss.ocaml.org/t/ann-ocaml-protoc-plugin-1-0-0/4535/1>


Anders Fugmann announced
────────────────────────

  I'm happy to announce the second release of 
  [ocaml-protoc-plugin].

  Ocaml-protoc-plugin is a plugin to googles `protoc' compiler 
  which
  generates type idiomatic to ocaml from `.proto' files including 
  full
  compliant serialization and deserialization functions.


[ocaml-protoc-plugin] 
<https://github.com/issuu/ocaml-protoc-plugin>

Most noteworthy changes in this release:
╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌

  • Full proto2 support.
  • The list of dependencies has been slimmed way down, and now 
  only
    depends on `conf-protoc' (the `protoc' compiler and googles 
    *well
    known types*).
  • Buckescript support.
  • Added options to change the ocaml (type for scalar types (int, 
  int64
    or int32).

  Many thanks to Wojtek Czekalski for helping trimming 
  dependencies and
  for Buclescript support.


Full changelog:
╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌

  • Support enum aliasing
  • Avoid name clash with on 'name'
  • Fix code generation when argument contains a path
  • Refactor internal types to make serialization and 
  deserialization
    type spec symmetrical.
  • Optimize deserialization for messages with max_id < 1024
  • Don't depend on Base in runtime
  • Slim runtime dependencies: Remove need for base, ocplib-endian 
  and
    ppx_let
  • Honor [packed=…] flag.
  • Make fixed scalar types default to int32 and int64
  • Support proto2 specification
  • Add options to switch between int64|int32 and int
  • Fix name clash problem with special enum names
  • Refactor serialization and deserialization to simplify emitted 
  code
  • Eagerly evaluate serialization (for speed).

Rudi Grinberg announced
───────────────────────

  Dear Vim & Neovim users,

  I would like to announce that I've officially moved the 
  [vim-ocaml]
  repository under the control of the OCaml organization on
  github. Please direct your bug reports and pull requests to this
  repository. This move is done not because vim-ocaml is being
  neglected, on the contrary, there's an active team of 
  maintainers that
  recently expanded. I simply want to take this opportunity to 
  draw more
  Vim & Noevim users to this project, as I suspect many users 
  aren't
  aware of recent efforts.

Mirage 3.7.1 released
Old CWN


Mirage 3.7.1 released
═════════════════════

  Archive: 
  <https://discuss.ocaml.org/t/mirage-3-7-1-released/4634/1>


Hannes Mehnert announced
────────────────────────

  MirageOS 3.7.1 is released to opam repository now.

  Breaking change:
  • The hooks previously defined in
    OS.Main.at_enter/at_enter_iter/at_exit/at_exit_iter are now 
    part of
    Mirage_runtime (only used by mirage-entropy)
    <https://github.com/mirage/mirage/pull/1010>

  Behaviour changes of MirageOS unikernels:
  • A unikernel now always calls the Mirage_runtime.at_exit 
  registered
    hooks – once a unikernel succesfully executed its `start' in
    `Lwt_main.run', `exit 0' is called to ensure this behaviour
    <https://github.com/mirage/mirage/pull/1011>
  • Top-level exceptions are no longer caught (there used to be in
    mirage-unix/mirage-xen/mirage-solo5 custom handlers). The 
    OCaml
    runtime prints the exception and backtrace on stdout and calls 
    exit
    2 (from 4.10.0, abort() will be called).

  Deprecations (being removed from Mirage 4.0)
  • All Mirage_YYY_lwt are deprecated, Mirage_YYY interfaces are 
  no
    longer astracted over 'a io and buffer. This reduces the 
    amount of
    opam packages - mirage-yyy-lwt are no longer part of the 
    release
    (each mirage-yyy package provides a Mirage_yyy_lwt module for
    backwards compatibility). Motivation was discussed in
    <https://github.com/mirage/mirage/issues/1004>
  • mirage-types and mirage-types-lwt are deprecated, please use 
  the
    Mirage_YYY signatures directly instead.

  Other observable changes
  • `mirage configure' now deletes all exising opam files

  Most reverse dependencies are already released to opam, have a 
  look at
  <https://github.com/mirage/mirage/issues/1012> for progress (and 
  the
  temporary <https://github.com/mirage/mirage-dev.git#easy> opam
  overlay).
