I’m asking because my package usually get several sales per month. but after latest package update, which I made on latest unity version 5.6.3, I stopped getting any sales. and it’s really strange that no any sale per latest month.
Maybe I need to rebuild package even for 5.2 version?
You should check out which Unity versions the top sellers support. Example: Mesh Baker supports 5.1.3 and 2017.1.0. No need to build for every major release between - just make one for the oldest you can support and one for the latest stable series.
August and September are traditionally slow months for Asset Store sales. However, it wouldn’t hurt to support a few versions back from the latest. But please test on the versions that have major API changes – 5.1.0, 5.2.0, 5.3.2, 5.4.0, etc. Add compiler defines to your code if necessary to compile without warnings or errors on these versions.
