+PROCESSING 3.0a6 (REV 0233) - XX April 2015
+
+This is the big one! We've jettisoned PApplet as the base class so that
+we can improve performance, reduce flicker, and have a better base from
+which to build better, more modern graphics rendering. More of the 
+gory details for the PApplet/PGraphics changes can be found here:
+https://github.com/processing/processing/tree/master/core
+
+Speaking of breaking things, we're on the road to a new GUI as well:
+https://github.com/processing/processing/issues/3072
+and that means all Modes and some Tools will need to be updated:
+https://github.com/processing/processing/issues/3080
+
+We've also made major changes to better integrate PDE X, Tweak Mode, 
+and other nice features for the default "Java" Mode. These will be the
+center of the changes for 3.x, which is focused on improving the editing 
+and debugging experience in general. 
+
+Suffice to say, this is truly an ALPHA quality release. We're pushing it
+out so that we can get more people testing it. If you want something more
+stable, we recommend 3.0a5 (not 2.2.1, that thing is old!) 
+
