Cyan Update - What changes do you notice?

The Cyan firmware update has started rolling out to Lumia devices. Nokia/Microsoft have already announced what major changes it will bring, but it seems like there are even more little changes that we might not have expected, so let's list them!

I'll start with a little detail I've noticed on my Lumia 925: The connectivity icons in the status bar (mobile, WiFi) now have a little arrow next to them whenever data is being transferred. So most of the time the arrow switches on and off, due to all the background processes that require connectivity. What's a little annoying to me is that the whole icon moves to the side when the arrow appears to make room for the arrow, so it looks like the icon is jiggling from side to side all the time.
