Content management system Drupal turns six years old, and celebrates with the official launch of version 5.0. The Drupal community is strong, and the team reports that over 492 people have contributed to the fifth version of the popular open source system.

Among the news weâ€™ll find a web-based installer, a new core team, improved usability, user and module administration, improved performance and a bunch of news for developers, including the addition of the jQuery JavaScript library. Thatâ€™s the latest craze by the way; WordPress 2.1 will include the Prototype JavaScript library.

The 4.7 branch will continue to be supported, but 4.6 are officially out in the dark so if you run that youâ€™d better upgrade to 4.7 or 5.0.

Thereâ€™s a series of videos in MP4 format to download if youâ€™re curious of Drupal. The last version I fiddled with was nice enough, and Iâ€™m definitely looking at the system for some projects.
