In August 2009 the development of DeepaMehta 3 started. Version 3 is a complete rewrite. The aim is to combine the lessons learned from DeepaMehta 2 with todays technologies and methods. A special focus is put on modularity and a flexible plugin developer framework.
DeepaMehta 3 is based on CouchDB and Lucene. The frontend is a single-page Ajax application, based on JavaScript, HTML 5, and its Canvas element. No Java for the moment.

After 3 and 1/2 years of work, 7 beta releases, 5 weeks after schedule, at Aug 7, 2020 DMX 5.0 has finally arrived.
The focus of this final milestone was on improving the DMX development experience. The APIs are consolidated, and a DMX Developer Guide is available, as well as API docs. There are minor Webclient UI improvements and crucial bug fixes as well. For more information and download link see this forum posting.
Note: since version 5 DeepaMehta is called "DMX".
DMX 5.0-beta-4 is released at July 22, 2019. Two and a half years in the making of DMX (formerly "DeepaMehta 5") this is the first release that provides Data Guarantee. That is when you install a newer version in the future (beta-5, …) your content will be migrated automatically. Start with DMX 5.0-beta-4 today and your content will be safe. Further highlight features and improvements of this release include Pinnable Detail Panel, up to 10 times faster topicmap rendering performance, improved interaction with topic/association details, and improved handling of HTML links.
