Major Changes

Bugs were fixed and cross browser support was improved. Problems with sound and font rendering persist but are now less common (browsers have to fix their bugs).

more self explanatory directory layout (to invite tinkering)
fixes gamejs.Surface.blit modifying passed in arguments
new setters: Rect.right, Rect.bottom
new utility: gamejs.utils.objects.accessors
event handling internal rewrite
experimental IE9 compatibility
docs improved

The future

Stay on course: shake out bugs. No new features in core (except if PyGame provides it).

Known Problems

Font rendering is buggy on Linux due to browser or OS bugs. It works fine on Windows. A workaround would be too ugly so GameJs will wait for browsers to fix their bugs. Font rendering is non-essential: in most cases it is Good Enough to provide bitmap texts.
The same is true for audio bugs: Chrome will not play short sounds and has problem with re-playing an already used audio element. The workaround would be Flash. Not acceptable.
