Twitter has updated its Twitter for Mac client, and you can see all of the new changes on the official company blog. The biggest update is that you now get a camera icon when you're composing a tweet, which makes it easier than ever to share pictures straight from your desktop (other Twitter clients have had this for a while, and you could always drag pictures over, but this is a clearer way to do this anyway). The app has also added Retina display support, which is nice, and there are now 14 more languages: Dutch, French, German, Indonesian, Italian, Japanese, Korean, Malay, Portuguese, Russian, Simplified Chinese, Spanish, Traditional Chinese and Turkish.
As always, the app is available for free directly from the Mac App Store. Twitter says to keep an eye out for more changes as well, so it's working hard on providing even more updates to the OS X app.
