WordPress has gotten a facelift. 3.8 brings a fresh new look to the entire admin dashboard. Gone are overbearing gradients and dozens of shades of grey — bring on a bigger, bolder, more colorful design!
I do like the changes in this release very much. @ Kendo - that is odd but likely because they made a lot of changes but you can find what changed by going to make.wordpress.com.
What's better is what's yet to come. I'm really liking the direction WordPress is headed and the level of supporting services. The quality bar is being raised across the community and it's becoming more visible.
