HelloHere is the latest OCaml Weekly News, for the week of November 05 to 12,
2019.

Hannes Mehnert announced ──────────────────────── MirageOS 3.7.1 is released to opam repository now. Breaking change: • The hooks previously defined inOS.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 inmirage-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 filesMost 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). Old CWN ═══════If you happen to miss a CWN, you can [send me a message] and I'll mail it to you, or go take a look at [the archive] or the [RSS feed of the
