Late last night the Android 4.2.2 (Build JDQ39) rolled out for GSM Galaxy devices, like the Galaxy Nexus, Nexus 7 and Nexus 10. As far as we know, it brings the usual range of bug squashing, although specifically it includes a Bluetooth A2DP audio streaming fix. Right now it looks like only a limited group of folks have started receiving the update, but that's the way update rollouts usually start. Hit up the source link below for some install instructions and a download if you want to grab it manually.

Thanks for the tip, grenefroggie!
