[ANNOUNCE] Xen 4.15 release update

[Ian Jackson <iwj@xxxxxxxxxxxxxx>]

I think all outstanding blockers have been addressed (although, not
necessarily in an ideal way), or will be today.

Please commit *all code changes* with a release ack
*by the end of today*.

I intend to cut a final RC on Monday (29th of March).  I hope to
release very soon after Easter (late in the week of the 5th of April).

The tree will continue to be open until the middle of next week for
docs and tests updates.  Apart from that code changes will not get
release acks unless they are low risk *and* fix serious bugs.

Ian.
