We're happy to announce that two new stacks have been added to the lineup: Django
Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Developed and used over two years by a fast-moving online-news operation, Django was designed to handle two challenges: the intensive deadlines of a newsroom and the stringent requirements of the experienced Web developers who wrote it. It lets you build high-performing, elegant Web applications quickly. The Django BitNami stack is currently available for Linux and OS X.
Tracks is a very cool Ruby on Rails web-based application that helps you implement David Allen's Getting Things Done methodology. The main editing functions are implemented with Ajax, so Tracks is very fast and easy to use. It also includes a lot of great features like RSS feeds and iCal exports.
