Our plan is to tag updates to community releases every two months. Since Koa was released as koa.1 on December 9th, we should make koa.2 tomorrow on February 9th.
You are welcome to join us if you want to see how it is done, and what friction points we have to work through. We’ll also record the session.
The steps are (somewhere) on this wiki page: Process to Create an Open edX Release.
