Some of the new Stuff is :
Option to have usernames auto-complete in the tweet box.
Option to automatically include hashtags when replying to messages.
Removing the ability to DM yourself, and in so doing stopping many of you from feeling foolish.
Updating the list of URL shortening services to the top 5 only and adding the Digg URL shortener.
Making it easier to tab between the tweet box and the shorten box.
Removing unread counter at top of each column. This has been making many of you feel stressed when you see thousands of unread messages and we don’t want to contribute to increasing your stress levels.
