Damien Doligez announced:
It is our pleasure to announce that the release of 3.11.2 is imminent.
What we need now is your cooperation for testing the release candidate,
especially on Windows.

The release candidate is available as source code at this address:
ftp://ftp.inria.fr/INRIA/Projects/cristal/ocaml/ocaml-3.11/ocaml-3.11.2+rc1.tar.bz2

See the list of changes at the end of this mail.

After testing this release candidate, please send a mail to
<damien.doligez@inria.fr> and tell us what you tested and whether
it worked.


Notes for Windows users:
- A recent update to Vista seems to have broken cygwin version 1.5.
 You will need to install the new version 1.7.1 instead:
 http://www.cygwin.com/
- You will also need the latest version of Alain Frisch's flexdll,
 version 0.21: http://alain.frisch.fr/flexdll.html#download


Happy new year's eve to everyone,

All successfully built packages are apt-able at (targeted at sid):

 deb http://debian.glondu.net/debian ocaml3112rc1 main

A summary of the successfully built packages is available at:

The repository is signed with my GPG key. Build logs and *.changes files
are next to their *.deb counterparts, unsigned.

I've pushed this out to Fedora Rawhide users after some very light
testing myself.  If there are any major problems we should see reports
from QA systems and users in a day or two.
