New this build: the much anticipated family behaviors and letterbox fullscreen modes, a new Dictionary plugin for associative data storage, and some other more minor additions, plus some changes and bug fixes.
Since this is the first beta release after a stable update, it's the best time for us to add new features. The new code will be tested and refined over the next few beta releases until it works smoothly, then it's ready for a new stable release. As usual new code means possible new bugs, so please watch out for new issues and post any you find to the Bugs forum!
Some people have been confused by the manual being updated with new features only in beta releases. For this reason, we will wait until the next stable release before updating the manual with the newly added features.
