The latest version of all our games remain Patreon exclusives until a newer version is available and then we look at public releases. Bountiful Harvest v0.3 has only been out a few weeks for patrons so it will be some time before a public release is available.
We'll do updates to the public versions at some stage. Our patrons make it possible for us to create expansion content full time so we're focused on delivering on our commitments to them first (which goes well beyond Bountiful Harvest).
