Release notes 

This release provides a significant new feature: Penn-Treebank-compatible POS tagging. This feature is currently "experimental", in that it has not been evaluated for accuracy; it appears to work reasonably well. It is currently intended only for use with the Stanford parser compatibility mode (thus providing Stanford-compatible POS tagging).

Another notable change is the fallback of using the standard Java sentence splitter if the OpenNLP-based sentence splitter is not installed. There are a number of bug fixes. Some of these improve POS tagging, while others provide fixes for operation with the OpenCog embodiment code.

IMPORTANT: This release *requires* link-grammar-4.6.5 or newer!
