Manual Android 4.4.1 update now available for Nexus 10

Unfortunately, we can't really say what those bug fixes are exactly. Most of the fixes and features that are known in the update target the Nexus 5, although we do know that at the very least there is at least one change that will affect the other Nexus devices: the default app for handling your images from the camera app is now the Google+ Photos app, rather than the stock Android Gallery app. 

Still, we're sure there are various bug fixes in the update, and eventually we'll see a proper change log from Google. In the meantime, you can sideload the update for your Nexus 10 if you want. All you need to do is make sure your Nexus 10 is running stock Android 4.4 build KRT16S, then download the update package from the source, and follow the same instructions as always.
