Version 1.1.0 Pre-release 2 (Build 1.1.0.214)

This release includes a major modification to the Kowari system architecture, known as Resolvers. Resolvers give Kowari the capability to query any type of data source by treating the data source as a graph. Also included in this release are features for improved performance plus support for XML Literal, XSD and unknown datatypes.
