Animation triggers can now be set via template bindings `[]` BREAKING CHANGE: animation trigger expressions within the template that are assigned as an element attribute (e.g. `@prop`) are deprecated. Please use the Angular2 property binding syntax (e.g. `[@prop]`) when assigning properties. ```ts // this is now deprecated <div @trigger="expression"></div> // do this instead <div [@trigger]="expression"></div> ```
