I'm passing along a lightly-edited announcement from the Red Hat
Bugzilla admins. You may have noticed this change already. The short
version is that the search API now defaults to returning 20 bugs, but
authenticated calls can request up to 1000.

More details are on the Community Blog:

I wonder if the RH Bugzilla team could synchronize with Fedora schedule next time, and avoid making potentially disruptive changes during an infra freeze...

(Yes, I'm still somewhat salty that BlockerBugs App broke during a blocker review meeting because of this).
