Oh interesting also Debian 14 Trixie here.
One more information: During the upgrade apt asked me whether I want to 
replace /etc/bird/bird.conf because it changed upstream in the usual 
ncurses interface. I selected 'keep the current configuration' or similar.

If there are other testers that can confirm what I'm seeing (autorestart 
on upgrade), please join.

thanks!
