Objective Caml 3.11.2 released.


Damien Doligez announced:
It is our pleasure to celebrate the birthday of Andre-Marie Ampere
by announcing the release of OCaml version 3.11.2.

This is mainly a bug-fix release, see the list of changes below.

It is available here:
It is source-only for the moment, but the binary versions will
be made available soon.

Note that there are still known problems under Windows with the
experimental procedure of building the system with ocamlbuild,
so you should build with make for the moment.

Happy hacking,

-- the OCaml team.
