Using Drupal's multisite feature, one can use a single codebase for multiple sites. This leaves a smaller footprint and makes your sites more maintainable since you only have to update one bunch of files.

This was already possible in versions prior to Drupal 7 by creating a configuration directory whose name was based on the site's hostname and pathname.

Although easy to setup this was sometimes cumbersome to maintain if you had different copies of your site running on different locations. During the creation of a site, one might typically maintain a development copy, an acceptation copy and a production copy. All these are on different locations. This would lead to creating several versions of the settings directory for one particular site.

In Drupal 7 a solution is provided for this particular problem. A new configuration file is available under the sites folder, called "example.sites.php". Using that file you can set up directory aliases. To see what those are, let's look at a particular example.

Yesterday, January 15, 2010 was a big day for Drupal. Our beloved CMS became 9 years old! And boy, did it mature well. To celebrate its birthday, Webchick (Angie Byron), Drupal 7's maintainer released the first alpha version of Drupal 7.

Since a lot of people are wondering what's new in version 7, I decided to gather a list where you can find this out.
