Unfortunately this means there will be no further backports of Calibre, and the existing package is technically in violation of backports policy. I've been investigating the feasibility of providing an unofficial flatpack based on the bullseye (testing) Calibre package, because I'm uncomfortable with the necessity to force-enable communication with newer Kobo firmware versions using the existing 3.48.0+dfsg-1~bpo10+1, and because I'm also uncomfortable running the upstream-provided package. Unfortunately that investigation has stalled for the moment... Thanks, Nicholas
