Does Community Edition upgrade monthly or quarterly?

Prior to the monthly releases it used to be auto-upgraded to the latest major within a couple of weeks, but that was never a hard date.

The documentation is confusing regarding this since it says that it runs the latest GA version. If it hasn't been upgraded yet, I would assume it's still on the quarterly schedule.

Would recommend emailing CommunityEdition@appian.com for more info.
