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.

Bug 修复

• $compile: ensure directive names have no leading or trailing whitespace (bab474aa,#11397, #11772)

• $httpParamSerializerJQLike: follow jQuery logic for nested params (2420a0a7,#11551, #11635)

• jqLite: check for "length" in obj in isArrayLike to prevent iOS8 JIT bug from surfacing (426a5ac0,#11508)

• ngAnimate:

• ensure that multiple requests to requestAnimationFrame are buffered (db20b830,#11791)

• ensure that an object is always returned even when no animation is set to run (d5683d21)

• force use of ng-anchor instead of a suffixed -anchor CSS class when triggering anchor animations (df24410c)

• rename ng-animate-anchor to ng-anchor(e6d053de)

• ensure that shared CSS classes between anchor nodes are retained (e0014002,#11681)

• prohibit usage of the ng-animate class with classNameFilter (1002b80a,#11431, #11807)

• ensure that the temporary CSS classes are applied before detection (f7e9ff1a,#11769, #11804)

• ensure that all jqLite elements are deconstructed properly (64d05180,#11658)

• ensure animations are not attempted on text nodes (2aacc2d6,#11703)

• ensure JS animations recognize $animateCss directly (0681a540)

• ngClass: add/remove classes which are properties of Object.prototype (f7b99970,#11813, #11814)

• ngOptions:

• ensure that tracked properties are always watched (b5a9053b,#11784)

• ensure label is watched in all cases (ae98dadf,#11765)

• iterate over the options collection in the same way as ngRepeat(dfa722a8,#11733)

• use watchCollection not deep watch of ngModel (47f9fc3e,#11372, #11653, #11743)

• ngTouch:

• check undefined tagName for SVG event target (74eb17d7)

• don't prevent click event after a touchmove (95521876,#10985)

新特性

• $resource: include request context in error message (266bc652,#11363)
