The Ubisoft Forums have patch notes for a new patch for Watch Dogs that's now live in North America and coming next week to the third-person phoner in Europe (thanks VG247). The new version adds replay options and drinking games to the solo campaign, and multiplayer improvements including the optional ability to hack your friends and punishment for bad actors:

Multiplayer Added Features

• HACK YOUR FRIENDS – You can now select available friends via the grid and hack or tail them without their knowledge. This can be disabled under online options. – (ALL PLATFORMS)
• CTOS MOBILE – Mobile players disconnecting will no longer result in the gameplay ending for the console/PC player. Console and PC players will play their match to the end and receive some Notoriety points for doing so. – (ALL PLATFORMS)
• MULTIPLAYER BAD BEHAVIOR – Players who are frequently disconnecting from multiplayer matches will be pooled together and paired only against players with similar online behaviors. – (ALL PLATFORMS)

If you’re playing against someone else who disconnects unfairly, you will get the same amount of Notoriety as if you had won at that moment.

The disconnector will not receive any Notoriety.
