Hey, Next MariaDB for Bullseye release tracked in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1000342
Status: the stable release team decided not to release the latest MariaDB 10.5.13 even though it was prepared and uploaded for Bullseye. Apparently on the grounds that Debian testing does not have a newer version (Debian unstable does have MariaDB 10.6.5 however) as it could cause unexpected non-upgrades for users who upgrade from Bullseye to Bullseye+1 at the time being. https://salsa.debian.org/mariadb-team/mariadb-10.5/-/commits/bullseye
