Hi Wei,

This email only tracks big items for xen.git tree. Please reply for items you
woulk like to see in $RELEASE_VERSION 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 twice a
year. The upcoming $RELEASE_VERSION timeline are as followed:

* Last posting date: $RELEASE_CUTOFF
* Hard code freeze: $RELEASE_FREEZE
* RC1: TBD
* Release: $RELEASE_DATE

Note that we don't have freeze exception scheme anymore. All patches
that wish to go into $RELEASE_VERSION must be posted no later than the last posting
date. All patches posted after that date will be automatically queued
into next release.

RCs will be arranged immediately after freeze.

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

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

I have started to include the version number of series associated to each
feature. Can each owner send an update on the version number if the series
was posted upstream?
