Release information such as features and timelines will not be revealed on this community as it is considered internal information.
You are encouraged to keep an active look out of the release announcements that go up on the PDN, like this one. You could also talk to your Pega Account Executive to keep you in the loop about these developments.
I read some of the SR case notes and it looks like you were advised to ask here and also create a Cloud Support Request ticket. I also read that there was a BUG resolution you were looking for in the next version of Co-Browse. I will see if I can get that information to you over a private message or through your Account Executive.
