[#12535](https://github.com/angular/angular.js/issues/12535))

## Breaking Changes

- **ngAnimate:** due to [32d3cbb3](https://github.com/angular/angular.js/commit/32d3cbb3aadf71492102f9318fcac570fb60bef8),

CSS classes added/removed by ngAnimate are now applied synchronously once the first digest has passed.

The previous behavior involved ngAnimate having to wait for one

requestAnimationFrame before CSS classes were added/removed. The CSS classes

are now applied directly after the first digest that is triggered after

`$animate.addClass`, `$animate.removeClass` or `$animate.setClass` is

called. If any of your code relies on waiting for one frame before

checking for CSS classes on the element then please change this

behavior. If a parent class-based animation, however, is run through a

JavaScript animation which triggers an animation for `beforeAddClass`

and/or `beforeRemoveClass` then the CSS classes will not be applied

in time for the children (and the parent class-based animation will not

be cancelled by any child animations).
