Newer version of Flock, a free web browser has been released just yesterday.

Flock is a fork of popular open source Mozilla Firefox browser and I’d say it is more intelligent version of Firefox. Flock has well polished interface with a touch of Apple style, many useful integrations with popular web services like Flickr and del.icio.us. Latest update from branch 0.7 directly to 0.9 is a significant sign of development that brought us a lot of new exciting features (nested tags folders) and interactions (YouTube, Blogger, LiveJournal and more).
