I'm hoping to start a monthly update schedule. In the first or second week of each month, a batch of updates will be released to the website and/or game server. This gives me the entire month beforehand to work on those features, and I'll be scheduling time to do exactly this amongst other work for my business.
Urgent bug fixes may be released outside this schedule.
Keeping the above in mind - the next release is due in early October. I will attempt to release at least one useful feature each month (not just bug fixes).
