We've added a couple of small fixes in this beta release, one that has to do with canvas names being incorrect on an export to HTML imagemap that was due to a different fix in beta 1, and Bézier lines should be back to normal, with the addtition of routing better according to their control handles when both endpoints are in the same location.
The beta's at the bottom of the download page, as are the release notes, short as they are.
