Heads up Snapchat users: Things are about to look a bit different. The messaging app rolled out an update Tuesday, which brings some changes to the Stories and Discover pages.

Now, directly below your own story, you'll see some headlines you might want to explore from publishers like CNN, Refinery29, PCMag's sister site IGN, and more. You can, for instance, currently check out IGN's New Mirror's Edge review, right from the Stories section. Below that is a grid of selected Live Stories from around the world, followed by updates from your actual friends.

Meanwhile, the Discover section now features a Pinterest-like grid of stories (above, right), instead of plain logos like before (above, left). And now, when you finish an edition in Discover, you'll have the option to subscribe so you never miss and update from that publisher. Then, going forward, subscriptions will appear below your friends' Stories.

Navigating the app should also be a little less confusing. Instead of swiping, you can now just tap the navigation buttons at the bottom to jump between screens.

In other social app news, Foursquare just launched an update for Swarm, which will let you score real-world perks just for checking in like you normally would. With Swarm Perks, you can nab discounts and prizes by checking into "a select and expanding roster of places — from big-box stores to coffee shops," Foursquare said. You might, for instance, unlock a 20 percent discount that you can use right away at the store or restaurant you just checked into.
