The admin interface has had quite a big redesign. I think it looks neater, but I’m sure it will take a bit of getting used to. The nice thing is it’s mobile aware now. If I run it on my Nexus 7 in landscape I get something similar to the browser view. If I switch to portrait it rearranges the screen to make it fit better. Neat.
The auto-updater (manually initiated) worked fine on 5 blogs, so not worries there.
