I don’t think it’s ever intended that the same number gets issued on different channels. The reason there’s a Release: 2.0.4.5 (beta) 2018-11-28 is because Release: 2.0.4.3 (beta) 2018-11-28 had a numbering conflict that could lead to confusion with Release: 2.0.4.3 (canary) 2018-11-13, and 2.0.4.4 was taken by a canary…
I have very little Docker experience, but can refer you OnedriveV2 not available as provider choice that got into this. Several of those users follow the forum (so might see this), and maybe someone else will also say. Possibly you could describe in advance how you’re changing your container. Is it a different one, or treated like a non-container system would typically be done, where you use Duplicati updater and manual changes.
