Text tool for whiteboard - Presenters can now annotate their slides with text.
New APIs - The BigBlueButton API now includes the ability to dynamically configure each client on a per-user bases, thus enabling developers to configure the skin, layout, modules, etc. for each user. There is also a JavaScript interface to control the client.
