I have received instructions from the Marketplace team to have the new release only compatible with 4.27 (which is the current at this date) and the release of UE5 is really approaching, which might cause the product some more changes. I was expecting to release 1.5 during March timeframe which might be correct unless I receive confirmation UE5 releases April, so better focus on UE5 instead of 4.27.
Anyway, there is no video tutorial done with 1.5, since I was including an extensive documentation in written form, and there are lots of differences from the current release when compared with 1.5, so it is not a smooth transition and detailed and well done documentation is key.
I strongly advice people who owns the package to get used to UE5 quickly, because my personal feelings is that UE5 is upon us and therefore the 1.5 will be release for UE5 only.
