Tweetie 1.2.7 -- not to be confused with the new Twitter for iPhone that supports multitasking -- is a minor upgrade from the previous versions. Users can expect small tweaks including increased security, bug fixes and a new advanced setting that supports updating iChat status.
Additionally the app, which is now available for free, no longer asks users to register their copy.
The full list of updates is as follows:
Increased security around your account.
Disable posting to image hosts using the deprecated authentication method.
Registration no longer needed. Section removed.
In accordance with the Twitter Terms of Service, on July 1 Fusion Ads will no longer be displayed.
Tweets no longer say they're from "Twitter for iPhone," but instead "Tweetie for Mac."
An option in "advanced" to update your iChat status when you tweet.
Improved Magic Mouse support.
Tweetie 1.2.7 for Mac won't blow away users, but as the update text reads, at least it will keep "the tweets flowing."
