For now, JSFUnit is on a traditional open-source release schedule. That is, we do a release when we feel like it's stable and we have added significant functionality and/or bug fixes. It is very likely that we will do the final 1.0 release in the next 3-6 months and probably a second beta very soon. My guess is that 1.0 final will be closer to 3 than 6.
Once the project is more mature we may decide to do time-boxed releases instead of the current feature-boxed releases.
