[Caml-list] Release candidate: 4.02.2+rc1

[Caml-list] Release candidate: 4.02.2+rc1

[Damien Doligez]

Dear OCaml users,

The release of OCaml version 4.02.2 is imminent.  We have
created a release candidate for your testing pleasure. It is very
easy to install and test with opam, just type:
    opam update
    opam switch 4.02.2+rc1

We want to know about any show-stopping bugs, especially in the
compilation and installation phases.

This release candidate is also available as source code at this
address: < https://github.com/ocaml/ocaml/tarball/4.02.2+rc1 >

Happy hacking,

-- Damien Doligez for the OCaml team.

OCaml 4.02.2:
-------------

(Changes that can break existing programs are marked with a "*")

Language features:
- PR#6583: add a new class of binary operators with the same syntactic
  precedence as method calls; these operators start with # followed
  by a non-empty sequence of operator symbols (for instance #+, #!?).
  It is also possible to use '#' as part of these extra symbols
  (for instance ##, or #+#); this is rejected by the type-checker,
  but can be used e.g. by ppx rewriters.

Re: [Caml-list] Release candidate: 4.02.2+rc1

[Simon Cruanes]

[-- Attachment #1: Type: text/plain, Size: 12859 bytes --]

I just tried

    opam update
    opam switch 4.02.2+rc1
    eval `opam config env`
    opam install oasis

and got that message (camlp4 strikes again!):

    The following dependencies couldn't be met:
      - oasis -> extlib = 1.5.3 -> camlp4
      - oasis -> ocaml-data-notation | ocaml-data-notation >= 0.0.11 ->
    type_conv = 108.00.02 | type_conv >= 108.07.01 -> camlp4
    Your request can't be satisfied:
      - camlp4 is not available because it requires OCaml >= 4.03.0.

Cheers!
