ANNOUNCEMENT: Xen 4.6 RC2

Hi all

Xen 4.6 RC2 has been tagged. You can check out the tag 4.6.0-rc2 in xen.git.

We notice that tarball build is broken so we don't provide RC2 tarball. RC1
tarball was broken, too. We will fix the tarball build problem for RC3.

When reporting bugs, please send your bug report to
[email protected] <mailto:[email protected]>, present as much information as possible,
tag it with "BUG-4.6" and CC release manager ([email protected] <mailto:[email protected]>) and
relevant maintainers.

We also arrange a test day for RC2. It is on 2015 September 1, next
Tuesday.  See http://wiki.xenproject.org/wiki/Xen_4.6_RC2_test_instructions <http://wiki.xenproject.org/wiki/Xen_4.6_RC2_test_instructions>
for test instructions.
