Drupal 7, possibly the programmer's favorite CMS,  has arrived and to mark its launch Drupal 7 parties are planned across the globe today, January 7, 2011.

The open source content management system CMS Drupal, which powers some high profile websites including including WhiteHouse.gov and NASA has released its latest version. 

It is also possibly the most programmer attractive of the PHP based CMS systems because you can't get that much done unless you take to programming but if you do there is very little you cannot achieve.

Drupal 7 has been three years in the making, with code from thousands of contributors from over 200 countries.

Its highlights are billed as:

• Easy to use

A totally revamped administrative interface lets you and your audience navigate functionality with ease.
Update modules and themes directly from within admin.

• Flexible content

Define your own content types with the new Field API.
Add custom data fields not only to content but also to users, comments, taxonomies and more.

• Images and files

Drupal 7 supports image handling out of the box.
You can mix private/public files and store things directly on alternative filesystems such as S3.

• Built to scale

Support for advanced caching, master/slave replication, reverse-proxy and content delivery networks.
Handle more anonymous traffic with lazy sessions.
