When you log into your wordpress admin panel, you’ll see a message sitting on top of the panel that says “WordPress 3.0 is available! Please update now.”
WordPress 3.0 is the much awaited wordpress version, Matt and team has been working tirelessly to release this. Its one of the major wordpress updates. When you update it you’ll see your default theme changed. I like the inclusion of the short-link tab for all blog posts, the short-link tab will be useful to post links to facebook fan pages and other social networks.
