AngularJS 1.4.0.rc2 发布，此版本代号为：rocket-zambonimation，更新内容如下：
重大改进
ngAnimate
$animateCss: due to d5683d21, The $animateCss service will now always return an object even if the animation is not set to run. If your code is using $animateCss then please consider the following code change:
due to df24410c, Prior to this fix there were to ways to apply CSS animation code to an anchor animation. With this fix, the suffixed CSS -anchor classes are now not used anymore for CSS anchor animations.
due to e6d053de, if your CSS code made use of the ng-animate-anchorCSS class for referencing the anchored animation element then your code must now use ng-anchor instead.
due to 1002b80a, partially or fully using a regex value containingng-animate as a token is not allowed anymore. Doing so will trigger a minErr exception to be thrown.
ngOptions
** due to dfa722a8,
you are iterating over an array-like object, using the array form of the ngOptions syntax (item.label for item in items) and that object contains non-numeric property keys.
