I just glanced at my phone to see that a new update to Google+ is now available. The changelog mentions that there’s a new “What’s Hot” section under Stream, a “trending topics” for Google+, basically. You’ll get to scroll through posts getting a lot of traffic, +1’s and comments so you won’t miss all the compelling discussion that Google+ has to offer.
That’s not the only thing they’ve added, though. You can now view who +1’d a post or comment, whereas before you could only view the amount of +1’s for comments and only the first person who +1’d your post.
Stream posts have been shortened so that you can see more of your list of posts on the screen at the same time. Finally, the stream will no longer jump to the top after an automatic refresh. Google has also mentioned that there are massive performance improvements. Find the update in the market here.
