Program D 4.6

Program D is the most widely used free ("open source") AIML bot platform in the world. Program D project is the most feature-complete, best-tested implementation of the current AIML specification.
It supports unlimited multiple bots in a single server instance, and has an open-ended architecture for interacting via any interface imaginable. The standard release provides a J2EE web application implementation that can be deployed as a .war file. Drop-in listeners are available for IRC, ICQ/AIM, and Yahoo.
It includes an automated testing framework for testing knowledge bases, and is packaged with an AIML Test Suite that verifies that the program itself complies to the AIML specification.
Program D is known to work with many different languages / character sets.
Its component-oriented architecture allows it to be integrated into any application framework desirable. It is implemented in Java, and uses many features of the latest JDK to provide optimum code reliability. It is actively maintained and supported.
Enhancements:
- This is a highly-recommended release which introduces some interesting performance improvements, fixes a number of important bugs, and brings some major architectural improvements.
- Most notably, Program D can now be deployed as a .war file to a Web application server, and can interact with a Web client using "AJAX" technologies.
- This final release follows three release candidates which ironed out a few minor issues.
