 Don't try to use MotionCAPTCHA v0.2 in production - watch and wait for the full release!
 
 **Update 22-08-11:** For everyone who's been watching, my apologies for not updating you sooner. The response to MotionCATPCHA has been amazing, and I still have big plans for it, but work and other distractions got in the way - to everyone who still wants to see MotionCATPCHA become fully-fledged and being used on live sites and apps, watch out for a codesmash day in September (possibly the 10th!)

 ### v0.3
 * Try to fix up IE support via excanvas or similar library
-* Add a real functionality for a 'new shape' button (a shape-switcharoo method)
 
 ### v1.0
 * a) Combine with a simple PHP CAPTCHA and server-side checking script, for progressive enhancement. By default, form is submitted with regular CAPTCHA. On page load, if browser supports JavaScript and HTML5 Canvas, regular CAPTCHA is switched for mighty MotionCAPTCHA, and that would be checked on the server instead.

 Don't try to use MotionCAPTCHA v0.2 in production - watch and wait for the full release!
 
 **Update 22-08-11:** For everyone who's been watching, my apologies for not updating you sooner. The response to MotionCATPCHA has been amazing, and I still have big plans for it, but work and other distractions got in the way - to everyone who still wants to see MotionCATPCHA become fully-fledged and being used on live sites and apps, watch out for a codesmash day in September (possibly the 10th!)

 ### v0.3
 * Try to fix up IE support via excanvas or similar library
+* Add a real functionality for a 'new shape' button (a shape-switcharoo method)
 
 ### v1.0
 * a) Combine with a simple PHP CAPTCHA and server-side checking script, for progressive enhancement. By default, form is submitted with regular CAPTCHA. On page load, if browser supports JavaScript and HTML5 Canvas, regular CAPTCHA is switched for mighty MotionCAPTCHA, and that would be checked on the server instead.
