Update: RIFE 1.0 has been announced on The ServerSide and a nice discussion is going on there, join us!

After four years of development and seventy releases, we finally consider RIFE to be feature-complete.

The project has come a long way over the years and the goals have been constantly re-evaluated against production projects and newly introduced technologies. RIFE is now running on sites with 300000 daily page views, it is used for critical systems in a leading telephony company and has scaled down to embedded usage in mobile phones. We have also developed several other open-source projects with it like a forum (Bamboo), a blog (Elephant), an information bot (Drone), and a to-do list tracker (Bla-bla List).

Below are the highlights:

• Greatly improved documentation [ more ]
• Backwards incompatible changes [ more ]
• Content syndication [ more ]
• Callbacks [ more ]
• SOAP improvements [ more ]
• Attachment and HTML support for mail queue [ more ]
• More production configuration parameters [ more ]

Congratulations and many thanks to everyone who contributed to make this milestone happen.
