Looks like the latest Android update is hitting Nexus based phones today! I got mine this morning. For those android users without nexus phones – sorry, thats what you get for buying phones with bloatware:)

Here is what the update does:

• Fixed Bluetooth audio streaming bugs
• Long-pressing the Wi-Fi and Bluetooth icons in Quick Settings now toggles the on/off state
• New download notifications, which now shows the percentage and estimated time remaining for active app downloads
• New sounds for wireless charging and low battery
• New Gallery app animation allows faster loading
• USB debug whitelist
• Bug fixes and performance enhancements
