The Dojo Foundation released version 0.9beta of The Dojo Toolkit. Though still in Beta, 0.9 is a better, faster, and more cohesive way to incrementally upgrade the Open Web and make your applications shine.
SPEED: Stripped of all 'excessive', redundant, and backwards-compatible code, the new Dojo core is a speed-demon. It consists of a streamlined, compact Base (aka: dojo.js) which provides a plethora of reliable features for you and your application to expand upon. Our goal was to keep the new Base under 50K on disk and we're happy to say that even with the many improvements to it since M2, Dojo Base still clocks in under the wire and gzipped it's even smaller: 24K. The base of the new widget system (dijit.js) is even lighter, weighing in at 21K on disk and 11K on the wire.
