2.9.0
90853aa

This release contains fixes across the entire project uncovered during the creation of the official .NET port of this project. This new implementation was originally ported from Java to C# by Yakov Danilov (for Imazen LLC). Since then it's been heavily refactored. Going forward, it will be kept functionally equivalent to the Java implementation.
