[ANNOUNCE] Xen 4.14 Development Update

[Paul Durrant]

*** ONE WEEK UNTIL LAST POSTING ***

This email only tracks big items for xen.git tree. Please reply for items
you would like to see in 4.14 so that people have an idea what
is going on and prioritise accordingly.

You're welcome to provide description and use cases of the feature you're
working on.

= Timeline =

We now adopt a fixed cut-off date scheme. We will release about every 8
 months.
The critical dates for Xen 4.14 are as follows:

---> We are here
* Last posting date: May 1st, 2020
* Hard code freeze: May 22nd, 2020
* Release: June 26th, 2020

Note that we don't have a freeze exception scheme anymore. All patches
that wish to go into 4.14 must be posted initially no later than the
last posting date and finally no later than the hard code freeze.
All patches posted after that date will be automatically queued into next
release.

RCs will be arranged immediately after freeze.

There is also a jira instance to track all the tasks (not only big)
for the project. See: https://xenproject.atlassian.net/projects/XEN/issues.

Some of the tasks tracked by this e-mail also have a corresponding jira task
referred by XEN-N.

There is a version number for patch series associated to each feature.
Can each owner send an update giving the latest version number if the
series has been re-posted? Also, can the owners of any completed items
please respond so that the item can be moved into the 'Completed' section.

Unless issues are found with this, it can be moved to "completed" -

Someone just drew my attention to the commit so once it hits master it should indeed be marked as such.
Thanks,

I'd like to take this as an opportunity to ask on the disposition
of this series: Under the new rules in principle I could have put
this in with Paul's R-b, but given the prior discussions I didn't
want to do so without at least an informal okay from you, Andrew.
Now that the sending of v5 as well as Paul's reviewing of it is 6
weeks back, I guess unless I hear otherwise pretty soon I'm going
to commit the remaining 3 patches some time next week.
