New look
New color scheme that is a lot prettier IMO.
64-bit canvas
This version has switched to a 64-bit canvas. The previous versions provided about 300 screens or so of actual canvas when fully zoomed-out. Switching to 64-bit is enough for Milton's canvas to really be infinite for any practical purpose.
Blur
There is a new layer effects window which currently supports one new effect - Gaussian Blur.
Bug fixes
Bugs were squashed.
Linux
Linux is still not 100% supported, but it's getting usable for those of you who would like to compile from source.
