The New Google Webmaster Tools is now available for all users. The new Google Webmaster Tools offer you better user interface and most of the content has been re-organized.

From the dashboard, for example, now you can see the Top search queries, Links to your site, Crawl errors, and Sitemap information.

As per Google Webmaster Blog:

From today, only the new user interface will be available (http://google.com/webmasters/tools)! You’ll see that in addition to fixing many of the issues users addressed, we took some time to launch a new feature: Change of Address. The Change of Address feature lets you notify Google when you are moving from one domain to another, enabling us to update our index faster and hopefully creating a smoother transition for your users.
