A significant enhancement in this version is the ability to create draft posts from the connection box. The idea is to be able to make the connections first and then write the content. Hat tip to Oren Kolker.

Finally, there are 3 new query vars that can be used to get connected posts ordered by a particular connection field. More details on the wiki:
