[ANNOUNCE] Xen 4.15 release schedule and feature tracking

The last posting date for new feature patches for Xen 4.15 is
tomorrow. [1]  We seem to be getting a reasonable good flood of stuff
trying to meet this deadline :-).

Patches for new fetures posted after tomorrow will be deferred to the
next Xen release after 4.15.  NB the primary responsibility for
driving a feature's progress to meet the release schedule, lies with
the feature's proponent(s).

  As a reminder, here is the release schedule:
+ (unchanged information indented with spaces):

   Friday 15th January    Last posting date

       Patches adding new features should be posted to the mailing list
       by this cate, although perhaps not in their final version.

   Friday 29th January    Feature freeze

       Patches adding new features should be committed by this date.
       Straightforward bugfixes may continue to be accepted by

   Friday 12th February **tentatve**   Code freeze

       Bugfixes only, all changes to be approved by the Release Manager.

   Week of 12th March **tentative**    Release
       (probably Tuesday or Wednesday)

  Any patches containing substantial refactoring are to treated as
  new features, even if they intent is to fix bugs.

  Freeze exceptions will not be routine, but may be granted in
  exceptional cases for small changes on the basis of risk assessment.
  Large series will not get exceptions.  Contributors *must not* rely on
  getting, or expect, a freeze exception.

+ New or improved tests (supposing they do not involve refactoring,
+ even build system reorganisation), and documentation improvements,
+ will generally be treated as bugfixes.

  The codefreeze and release dates are provisional and will be adjusted
  in the light of apparent code quality etc.

  If as a feature proponent you feel your feature is at risk and there
  is something the Xen Project could do to help, please consult me or
  the Community Manager.  In such situations please reach out earlier
  rather than later.

In my last update I asked this:

> If you are working on a feature you want in 4.15 please let me know
> about it.  Ideally I'd like a little stanza like this:
> S: feature name
> O: feature owner (proponent) name
> E: feature owner (proponent) email address
> P: your current estimate of the probability it making 4.15, as a %age
> But free-form text is OK too.  Please reply to this mail.

I received one mail.  Thanks to Oleksandr Andrushchenko for his update
on the following feeature:

  IOREQ feature (+ virtio-mmio) on Arm

  Julien Grall <julien@xxxxxxx>
  Oleksandr Tyshchenko <oleksandr_tyshchenko@xxxxxxxx>

I see that V4 of this series was just posted.  Thanks, Oleksandr.
I'll make a separate enquiry about your series.

I think if people don't find the traditional feature tracking useful,
I will try to assemble Release Notes information later, during the
freeze, when fewer people are rushing to try to meet the deadlines.
