There won't be another 3.x release. The 4.0 release is just about ready, as you read, with us just waiting on the updated code from Facebook. We can't really release what we have in a new 3.x series because we've changed some of the code to make improvements, but it breaks backward compatibility in a few ways for user's who have custom coded their own modifications. Nothing major, and very easy updates, but we are moving to the name 4.0 so we can easily delineate what's available in what release and easily debug issues if a user's using 3.x or 4.x in the future.
Additionally, we try to avoid 2 back-to-back releases when possible. We did it once in the past and got -a lot- of flack from users. Even with new features, constantly upgrading seems to rile some feathers.
With that said, we're still in a holding pattern waiting for Facebook's release which support their new authentication mechanism. This method will be required by Facebook as of Oct 1st, so we want to get it out as soon as possible to make sure everything goes smoothly for the migration. Originally, it was supposed to be out July 1st.. then the 20th, then the 29th. It was delivered on Friday, and we're waiting to hear the next release date. It should be next week, and our updates to use it should be quick.. so, hopefully the 2nd week of August is looking good.
Regarding invites, we agree, it could be better.. and that's something we're definitely investigating for 4.1. The new Requests system can do a lot more than just invites, which is very cool, and we are investigating a lot of ways to integrate and take advantage of the system. I'm not sure what the invite log-out bug you're seeing is.. first I've heard of it. Can you try our demo site (
www.sourcecoast.com/jfbconnect/demo) and see if you have the same issue there?
Finally, for JomSocial, again, we agree, there's definitely more that can be done there too (there always is). We're always adding more integration points for extensions and working toward exactly the things you mention. With posting to walls, we think it's pretty easy to post links to videos and other rich media, and plan to add that in a future update to the activity plugin.. the plugin we released was the first rev, and after 4.0 finally comes out and any bugs/issues settle out, we want to add more to that plugin for tighter integration.
Hope that all helps and answers your questions!
