Lovin’ 2.1 so far, you should too if you have’nt already here’s a few changes in this version

# Autosave makes sure you never lose a post again.

# Our new tabbed editor allows you to switch between WYSIWYG and code editing instantly while writing a post.

# The lossless XML import and export makes it easy for you to move your content between WordPress blogs.

# Our completely redone visual editor also now includes spell checking.

# New search engine privacy option allows you take you to indicate your blog shouldn’t ping or be indexed by search engines like Google.

# You can set any “page” to be the front page of your site, and put the latest posts somewhere else, making it much easier to use WordPress as a content management system.

# Much more efficient database code, faster than previous versions. Domas Mituzas from MySQL went over all our queries with a fine-toothed comb.

# Links in your blogroll now support sub-categories and you can add categories on the fly.

# Redesigned login screen from the Shuttle project.

# More AJAX to make custom fields, moderation, deletions, and more all faster. My favorite is the comments page, which new lets you approve or unapprove things instantly.

# Pages can now be drafts, or private.
