Re: [Xen-devel] Xen 4.12 release planning

Hi Juergen,

Its time to plan the Xen 4.12 release dates.

There have been concerns with the schedule of 6 months between releases,
as this scheme is leading to too many supported versions of Xen at a
time. The needed resources to backport bug fixes and security fixes as
well as doing the tests for all those releases are a limiting factor to
push out the current main release as well as point releases on time.

After some discussions at the Xen developer summit, on xen-devel and
between the committers a slightly longer release cycle of 8 or 9 months
was suggested.

With 18 months of full support and 36 months of security support the
number of concurrent supported releases will be the same with either 8
or 9 months release cycles, so I have chosen an 8 month cycle for now.
Having only 3 possible times in the year for a release will make it
easier to avoid major holiday seasons. >
In case there is no objection I'm planning Xen 4.12 with:

* Last posting date: December 14th, 2018
* Hard code freeze: January 11th, 2019

In general, you would expect western people to slow down during Christmas period and have to deal with a pile of e-mail just after New Year. So I think, this is not very convenient period for a code freeze.

I usually take more holidays around Christmas and New Year. For this year, I will be on holidays from 21st December until the 13th January. This basically means my cut off for Arm patches will be 21st December or potentially few days before to avoid having the likely last minute rush.
