That's right, the following two changes were made to your editor today:

1.) As you type, your posts are saved every 30 seconds (this may be extended to every 1 minute, depending on server load)

2.) Posts are now 'draft' by default and can be switched to either 'Published' or 'Private'

Ahhhh progress.

3.) You now have a WYSIWYG editor (TinyMCE).

That is all. :)
