TweetDeck is one of the (if not) largest Twitter desktop clients out there, and whilst it has looked the same in nearly all iterations, it has been on something of a run in the past few months with features.

Extending on the large notifications brought with the last big update, the company is rolling out a new version that hooks into Twitter via its OAuth-powered protocol rather than relying on simply entering your password into the application. This should aid security, as well as making syncing easier.

Elsewhere in the update comes support for YouTube and Flickr. Both services will show their respective content in preview boxes within the application (rather than opening a new browser tab), making it simpler and easier to see content.

It also allows you to view images from more popular services like Posterous, Mobypicture and Twitgoo.
