Foursquare just pushed out version 5.1 of their iOS app. Despite the jump in version numbers, you won’t find any new features in this update. It’s simply a bug fix release that nails a few of the nastier bugs that crept into the 5.0 release.
One that’s been fixed is the bug that prevented you from swiping between photos on the venue page or user profile pages. You no longer have to go back and select each one to see it.
Foursquare has promised that a future version will include the nearby vs. worldwide filters that were removed in version 5.0. That change does not appear in this update.
You can download the update from the iTunes app store.
