Overwatch's long-awaited Symmetra rework is now playable on the Overwatch PTR. She's now classified as a Defense hero, not a support, and her kit has been overhauled significantly. Here are all her new abilities:

The biggest change to Symmetra’s primary fire is that it no longer locks onto enemies. This change, in turn, allows the weapon to deal significantly more damage and have increased range. While Photon Projector’s damage ramps up more slowly than previously, it also ramps down more slowly which makes it easier to maintain for the duration of a big fight.
