After 2 years of working continuously on fixing user issues and adding feature after feature and trying to please everyone even when some people were asking for contradicting features, I needed a break.
Lunar 3.2.3 was the last Lunar 3 release which I deemed stable enough that I don't need to care much about it anymore.
Some users were very supportive and donated close to $5000 in the course of 3 years which helped pay for Apple certificates, server hosting and hardware for building an ambient light sensor.
But some were downright abusive and I felt I needed to pause before investing any more time into this app.
