Beta software is pre-production quality software. It is released with the intention of providing the software's users with insight into where the software feature-set is going for a particular release cycle, getting as wide a base of testers for the release as possible and gauging the uptake of new features.
The software may not be entirely complete yet and may be buggy. We highly value your input and urge you to evaluate the software in a test environment. We do however strongly suggest you do not to implement this version of KnowledgeTree in a production environment as we can't warrant it functioning correctly.
