Release Notes: A major rewrite of the engine. The knowledge database is now sorted by topics, and new HTML parsing and phrase scoring algorithms are implemented.
Release Notes: This release adds a modified substring rating algorithm and an experimental change to the algorithm to support pseudo context-tracking in a conversation by decreasing instead of clearing sentence scores.
Release Notes: Another nasty logic bug has been resolved; the algorithm would only check for substrings starting at the first word of each sentence.
Release Notes: A fix for a serious logic and performance problem that affected the quality of conversation, and some minor performance tweaks.
