Hi -
You may or may not be aware that a not insignificant portion of your user base use trackers that heavily restrict the specific versions of clients they allow to connect (applies to any torrent client, not just qbit, so the following feedback applies to all the clients you distribute). Most that I'm aware of have blanket approvals for qBit 5.0.x, but the recently released 5.1.x remains verboten.
With the information available in the Unraid update UI, I have no idea of accepting the update will break my ability to connect to such trackers.
I would ask at a minimum that you include a changelog that includes the specific version of the given torrent client contained therein.
My personal sanity would ask that you provide a docker tag for at least for each major/minor version (e.g., an update channel each for 5.0.x and 5.1.x in the case of qbit) so that I don't have to ignore an update until all my trackers support that version.
