I'm happy to announce that a pre-release version of the Java Topology Suite
is now available for download at
http://www.vividsolutions.com/jts/jtshome.htm

This version is functionally complete (apart from isSimple and isValid,
which will be release shortly).  

The spatial predicates are robust under both Fixed and Floating precision
models.  The spatial overlay and buffer functions are unfortunately not
fully robust.  The overlay functions should perform similarly to most other
spatial APIs, however.  The buffer function is robust and precise for many
inputs, but does have known failure cases.

We invite comments, and especially suggestions on robust, precise
algorithms.
