Hello everyone,

The hard code freeze for Xen 4.21 runs from October 4, 2025, to October 31, 2025.

Bug fixes for serious issues (including regressions) and low-risk fixes may
continue to be accepted by maintainers during this period.

R-Ack is requited during this period.

Please add me in CC for any bugs or fixes you believe should be included
in the current release.

Thanks, and have a great weekend.
Best regards,
 Oleksii
