I want to thank all of you who have provided feedback. Your input has been absolutely valuable in ensuring that we produce a high-quality update. Thank you for your patience and as always, we look forward to hearing your feedback on this one.
This will be an incremental rollout. We should reach 100% coverage in the next 48 hours or so.
Here are some of the highlights of this update:
Enabled sRGB mode in developer options.

Enhanced audio playback quality.
Updated custom icon packs.
Fixed some issues with notifications.
Improved camera quality/functionality.
Fixed some issues in Gallery.

So let us know what you think. Enjoy!
Since then, staff member "Sam L" has said the following: "Due to some reports of issues while upgrading, we are temporarily stopping the rollout to investigate. We will start back up as soon as possible."
