The next release will be R14B01, expected to be released
in December.

The next time I'll send out this email (probably next

This topic branch has a failing test case:

    We have now tested with and without this topic branch and when
    it is present that test case fails. We consider it proved
    to be guilty. The test case does not fail when run standalone
    so it seems to be tricky... Also, some of its own test cases
    fail sporadicly.

Action expected from: Topic author.
