Added a default access for messages in the user profile configuration of activity settings, much like facebook does its privacy settings.

#1363382 by sw3b: Fixed Error on viewing single activity and the date field do not reflect permission.

#1250324 by solomonrothman: Added Alpha version of shout box released for D7, What can we do to make it work with heartbeat?.

Big refactoring to have heartbeat activity as a complete entity. Also fixed a bug: #1284376 by Sylense: Fixed Overriding activitycomments plugin breaks comments.

Refactored the setting for the profile page path to be consistent with the normal path. Leaving empty and full control over the path. Validation check should be added to avoid existing paths (E.g. conflict with other activity modules).

Fixed the pager so it works for all ajax calls to fetch older messages. This means separation of the normal page callback that would not return ajax anymore.
