The OYSTER project has moved to Bitbucket.org
There you will find the newest version 3.6.4 with many additional features and improvements.
There are also a number of demonstration runs already setup for a quick start.
The complete Oyster 3.1 download previously did not contain the source code. The new 3.1 contains the full distribution package. Going forward you can expect the distribution package to contain the binary, source, licesne, change log and readme file.
Oyster GUI is almost ready for release. Currently at Version .99 Beta we are doing some final testing and soon you will be able to download Oyster 3.1 GUI 1.0 here on sourceforge.
