This new Social Stream’s minor version comes with migrations on activity objects.
We have realized that all the activity objects (posts, comments, documents, pictures, audios, videos, events and links) are sharing two common attributes: title and description. So we have moved them to the activity_objects table.
This simplifies a lot some code in notifications and makes things easier if your are building your own activity object. You have now those fields available for free!
There are also a bunch of fixes, most of them regarding the presence gem, which is now persistent along all the application and has a new search interface.
Do not forget to run
