What exactly do I get with Patreon? Do I need to stay subbed to get new versions? How about using the software if I'm no longer a patron? Is there a list of features, i.e. how the "paid" version differs from this free one?
You can get new downloads as long you tay subbed, you can keep using the application forever if you cancel the sub. The Patreon version already have a lot of new stuff and use less memory to run the model.
