These Overwatch Beta Patch Notes offer details on the latest update to Overwatch as Blizzard works on the upcoming launch of this multiplayer shooter (thanks Ten Ton Hammer). The update adds a new map, resets player's career profile stats (but not matchmaking), and a number of changes and tweaks, as well as some secret stuff, as they admit "some changes may not be documented or described in full detail." Here's word on the new map and the stat reset:

New Control Map: Ilios
Situated atop a small island rising from the Aegean Sea, Ilios is a postcard-perfect Mediterranean town, with a bustling harborside, winding paths for rambling hillside strolls, and gorgeous vistas. It is the ideal vacation stop for people looking for a place to relax, or for those interested in exploring the ruins scattered at the top of the island, where many artifacts and relics of the ancient world have been recently unearthed.

Career Profile Reset
This patch includes a full wipe of players’ Career Profiles. As a result, the Career Profile page will appear empty when you first log in after patching, and your previous "Personal Best" records will be reset. (Note: This wipe will not affect matchmaking, player levels, progression, or rewards.)
