Circle gets updated with LinkedIn support and bug fixes.

Circle is described by its developers as the local social network. No it's not yet another social network but simply an app that uses your location to let you see your Facebook friends who happen to be in your neighborhood and interact with them and, eventually, meet up for a beer. A cool app to use in your city or when visiting another one. 

Check out the change log:

-- Ability to log-in with LinkedIn!
-- Many bug fixes
-- New visuals on many screens
-- Faster and better way of getting your location
