Iain Dodsworth has released the latest version of his Adobe AIR-based Twitter client, TweetDeck. Changes included integration with LinkedIn accounts, the capability to geotag tweets with your location, the option to choose between Twitter's new style for retweets and the old style, and an improved interface featuring a new Add Column screen. Also, support for Twitter's new list feature (see "Twitter Adds Lists, Finally," 30 October 2009) has been added, ensuring full compatibility with Twitter while maintaining the functionality of TweetDeck groups. Old groups will still be available to you, but you won't be able to add any more new ones. A full list of changes and bug fixes is available on Dodsworth's Web site. (Free, 2.4 MB)
