WordPress 2.1  “Ella” has been finally released  . Along with 550 bug fixes , it includes any new and cool features . Some of them are

• Autosave makes sure you never lose a post again.
• The new tabbed editor allows you to switch between WYSIWYG and code editing instantly while writing a post.
• The completely redone visual editor also now includes spell checking.
• Redesigned login screen from the Shuttle project.
• The admin has been refreshed to load faster and be more visually consistent.
• A new version of the Akismet plugin is bundled

And lots more …. .

I would be upgrading to it in a short time when i get more info about the compatibility issue with plugins.
