7 October 2019 - macOS Catalina 10.15 has been released today by Apple.
The current version of iScreensaver (6.1.0) generally works with Catalina, but we have noticed a few small problems. You can go ahead and use 6.1 to build Catalina-compatible screensavers.
In particular, in Catalina, the integration of Photos.app (version 5) and iScreensaver is broken, and we will focus on this area.
We hope to release iScreensaver 6.2 this week which will improve this and a few other issues.

I have version 22.214.171.1240 and Catalina. But as soon as I installed Catalina, I noticed one thing that I did not have before: a notice in green type on my screensaver telling me my screensaver was not licensed for distribution. It never was (I checked off on that when I made it) but now I have this green thing I can’t get rid of.
Simply re-install the screensaver and it should work fine. Catalina changed where preferences files are stored on Catalina, so when you upgraded, it wiped out the information that this was a valid installation.
