Google has announced that Google+ is about to to receive a massive redesign over the next few days. What to expect:

# Instead of static icons at the top, there’s a dynamic ribbon of applications on the left.
# Once you’ve upgraded to Google+, it’s easy to share with your circles from just about anywhere.
# A dedicated Hangouts page that creates even more opportunities to connect in person
# There’s a new Explore page that shows what’s interesting and trending across the network. And a new profile with much bigger photos. And a new chat list that puts your friends front and center. And a whole lot more.
