- Categories - Woohoo! Can't wait to categorize my posts
- Privacy - Yeah! Can now choose your readers so need to do less self-cencorship
- Tagging - They've called it Labelling but it works the same way as Technorati Tags
- Designs - There'll be more templates to choose from and it'll be easier to change the look of your blog with new drag and drop elements.
- Others - Some other changes like more feed options, an updated dashboard and instant publishing
At the moment the changes are still in beta or test drive version. So existing users have to wait a while before getting a chance to upgrade (unless you have an upgrade link in your dashboard) but if you can't wait, you can start a new blog to test it out since you can create a new account using the beta version.
For poor people like me who can't afford to have my own domain, this is a welcome and long awaited change indeed. Yipeee!
