– Made the comments plugin smarter. The Settings page allows the “Send to Twitter” button on comments to be disabled. Just leave the field blank and voila, no more checkbox.
– And the big one: Automatic Tweeting on Post Publish. It supports auto-tweeting to an alternate Twitter account than your own (useful if you have a multi-user blog). Manual publishing will be coming soon, but I suspect it will not support the alternate account functionality, for simplicity. It would be confusing and hard to use.
Note: that last one is a bit beta. Don’t be surprised by bugs and odd behavior. Don’t rely on it working every time, because it probably won’t. But when it does work, it works great. Here’s this post, auto-tweeted: http://twitter.com/ottodestruct/status/10934354229 🙂
