Great.

So I can announce RC3 with the repository fork for Mon 01-Dec-2025 or Tue 
02-Dec-2025 at 11:00 RBT (Royal Bavarian Time). I will tell later which day it 
will be.

The fork will happen at the same time. Anything still happening on 
isabelle-dev until the fork is for Isabelle2025-1 release: It should be 
finalization / polishing of already present things, no new "features", no "bug 
fixes" for old problems from past releases.
