Far be it from me to look a gift plugin in the mouth, and however wants to do what he does is fine by me because it’s a marvelous gift to get.
But if—IF—the is the work spent updating/maintaining the plugin on two separate branches, I would THINK (again, not the expert here) that doing a single preview-compatible release just once when the preview first drops, and then just ignoring it, without worrying about keeping it updated with the rest of the main Victory Branch (until it gets replaced with the most recent Victory Plugin once the release goes official), would satisfy the general desire to test projects for bugs in preview releases without adding a particularly large amount of workload on your end, .
Again, just a thought, I would not presume to instruct how to provide us with a gift like the Victory Library if that’s not how he wants to do it.
