I upgraded my blog to WordPress 2.7 Beta 3 and i am very impressed at first sight Also with very nice plugins like Zemanta and Organize Series blogging is really a pleasure, thanks to them.

You can also upgrade your WordPress if you do not like installing your plugins every time by ftp, instead of manual install you can easily install/upgrade your plugins just like Firefox

Some new features:

• Plugin installer is the best improvement as i mentioned, saves you from lot’s of manual work
• Stylish design – new admin pages and menu are really cool and easy to use
• QuickPress feauture is added
• and more…
