Hard code freeze for Xen 4.20 is started

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

Hello everyone,

The hard code freeze date for Xen 4.20 is started from February 07, 2025
to February 21, 2025.

Bug fixes for serious bugs (including regressions), and low-risk fixes 
only may continue to be accepted by maintainers beyond this point.

For straightforward bugs and fixes, an R-Ack is not needed until the end
of hard code freeze date.
However, if you have any doubts, feel free to request an R-Ack explicitly.

Please add me in CC for the bugs and fixes you think should be in the
current release.

Thanks and have a great week!

Best regards,
  Oleksii
