I am pleased to announce the 113.24.00 release of the Core suite.

It has been 4 month and a half since the last release, so there are
lots of new things in this release. Thankfully we now have a better
release system and can go back to more frequent releases.

All packages are now in opam and the API documentation is here:

  https://ocaml.janestreet.com/ocaml-core/113.24/doc/

[Note: if you run into trouble while running "opam upgrade", try "opam
upgrade core" instead. A PR has been submitted to fix this]

Notable changes:

* This is the first release completely camlp4 free!

  Especially some problems with the initial release of our ppx
  rewriters have been fixed which make them more usable.

  As a side effect of moving from camlp4 to ppx_driver, compilation
  times have improved. From a fresh `opam init` in both case:

      $ time opam install -y core.113.00.00
      [...]
      real 6m17.875s
      user 5m26.374s
      sys  1m10.039s

      $ time opam install -y core.113.24.00
      [...]
      real 3m16.900s
      user 3m9.860s
      sys  0m53.335s

* We started to handle API upgrades in a more disciplined way by using
  `[@deprecated]` attributes. This should help with incompatible
  changes in our libraries

* Addition of a few ppx rewriters:

  - ppx_expect, a Cram like framework for OCaml
  - ppx_let, for monadic/applicative let bindings
  - ppx_sexp_message, similar to ppx_sexp_value, but more "message" oriented

  We are still making adjustments in ppx_let and ppx_expect so their
  usage might slightly change in the next release.
