That's it. The old Twitter design officially is gone and the New Twitter look and feel is all that's left.
Twitter unfurled a newly redesigned interface last fall, but the company allowed people to use the old interface until today.
The microblogging site announced in a tweet this afternoon that after nearly a year the old interface is history.
"New Twitter rollout: complete! All users now have the same Twitter.com experience & can access our latest features," the company said.
The newer version of the site, which is known on Twitter as #NewTwitter, has an expanded sidebar on the right with new features like maps of geo-location tagged tweets and embedded pictures and videos. The redesign also enabled users to click on tweets to drill down into them for more information.
Early last week, the company alerted users that if they were still using the old version of Twitter, time was running out. "If you're currently using Old Twitter, we want to let you know that you'll be upgraded to New Twitter this week," the company tweeted.
