Hello! I've prepared the 10.3.16 release for upload to unstable, and I will proceed with it in a couple of days.
If there is something you want to have a chance to get into next stable Debian release, now is your chance to act on it. There are no new pending merge requests at https://salsa.debian.org/mariadb-team/mariadb-10.3/merge_requests nor any critical open bugs. There is however one old MR as a suggested solution to #930314 https://salsa.debian.org/mariadb-team/mariadb-10.3/merge_requests/19 but I have not merged it yet since I am unsure if this is a good fix that will also be accepted by upstream some day or if we will get stuck with delta that we need to maintain for a long time. Comments welcome.
