Hello everyone,

This is an update on the current November 2025 stabilization week on our
Netflix A/B test deployment.
We had one significant finding:
dhw@ noticed a regression (higher system CPU utilization), which was
quickly troubleshooted by gallatin@, patched by chs@, and pushed by imp@.
This was excellent teamwork!
The fix is in the following commit:
"git: 2b4dbad2db57 - main - nda: fix setting of unmappedio flag"

On my end, my personal build machine, Workstation, NAS, and laptop have all
been upgraded, and I have not observed any further regressions.

Separately, reading the -current mailing list, thj@ reported an issue with
the 20251124 16-CURRENT snapshot, which appears to be very close to the
stabweek state. You can view the report here:
https://lists.freebsd.org/archives/freebsd-current/2025-November/009491.html

I will keep the stabilization window open for one more day to allow for any
final reports before officially closing the stabweek.

Regards,

Olivier
