When transition-delay and animation-delay were used to drive the staggering animation the result was unpredictable at times due to the browser not being able to register the generated delay styles in time. This caused a hard to track down bug that didn't have a solid solution when styles were being used. This fix ensures that stagger delays are handled by the $timeout service. Closes #7228 Closes #7547 Closes #8297 Closes #8547 BREAKING CHANGE If any stagger code consisted of having BOTH transition staggers and delay staggers together then that will not work the same way. Angular will now instead choose the highest stagger delay value and set the timeout to wait for that before applying the active CSS class.
AngularJS 
AngularJS lets you write client-side web applications as if you had a smarter browser. It lets you use good old HTML (or HAML, Jade and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. It automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding. To help you structure your application better and make it easy to test, AngularJS teaches the browser how to do dependency injection and inversion of control. Oh yeah and it also helps with server-side communication, taming async callbacks with promises and deferreds; and makes client-side navigation and deeplinking with hashbang urls or HTML5 pushState a piece of cake. The best of all: it makes development fun!
