Comment 2 for bug 1814458

Hi Kovid,
https://github.com/kovidgoyal/calibre/commits/master
Shows: RPUB/MOBI Catalog generation: Allow matching empty fields in exclusion rules. Fixes #1814458 [catalog builder ignore "any" and "undefined"](https://bugs.launchpad.net/calibre/+bug/1814458)
but titel refers to https://bugs.launchpad.net/calibre/+bug/1814459 which is not fixed acceptable upto now.

This is only fyi if you produce the release notes from that master.
Correct is:
EPUB/MOBI Catalog generation: Allow matching bool values ("any/undefined") in exclusion rules. Fixes #1814458 [catalog builder ignore "any" and "undefined"](https://bugs.launchpad.net/calibre/+bug/1814458)
