The following item is in the change log for release 1.31.1.6733:
(CreditsDetection) Fix assignment of final marker attribute (#14109)
I may not be interpreting the change correctly, but it made me wonder if a change is made to how credit markers are detected & assigned, what method is used to correct markers that had already been assigned prior to this (or any similar) change? I realize we can perform an Analyze on individual items to re-identify credits, but we’d have no way to do that on a mass scale.
I don’t think if this is being utilized for this or not, but the credits tag has a version attribute. That could be used to know which ones to “upgrade.”
