Midnight Plug-in Suite is no longer under development support, meaning we are not able to provide any further updates to support macOS Catalina or future versions of macOS or Windows.
Midnight Plugin Suite will continue to function as normal on macOS 10.14 Mojave and below and may potentially work beyond this, though this won't be tested.
The latest version of Windows that Midnight Plugin Suite was tested on is Windows 10 build 1809, again it's possible that the Midnight Plugin Suite will continue to work on newer versions of Windows, however this will not be tested.
