Facebook has rolled out a new main logo and refreshed the design of other icons for the first time in years, Mashable said.

Facebook's logo no longer includes the faint blue line at the bottom of its "F" icon. The letter is also pulled closer to the edge of the box.

Although this was first spotted on the information page for Facebook Home - the social network's new app launcher for Android - the new logo showed up in the company's newsroom webpage on Friday, April 19 according to web developer Tom Waddington for the site Cut Out + Keep.

The "F" logo hasn't been updated to all pages just yet, including the Brand Permissions page. However, it has been added as the picture to Facebook's Twitter account.

Other official pages have received logo refreshes in the past few weeks, from the security badge to the privacy icon. The redesigned logos feature Facebook's signature blue color as a background to create a more streamlined, uniformed look.
