Based on usual time between updates I think there will be an update in February. The dev said the next paywalled update is a 'Part 2' to the one we got in November though, and was also supposed to be out "sooner than usual" so idk exactly what the delay is at this point, could be a longer wait for the free version.
Kagetodev if you read this I'll definitely rejoin the SubscribeStar once there's a new version up, only left due to lack of updates/communication :/
