please note that we currently do not have much time to actively work on SOSlib. However, the library works fine and fast, and we have many happy users as it is!
We recommed that you use the development version rather then version 1.6.0. It has lots of improvements, lots of bugs were removed and no new ones found. We just didn't have time to make a nice official release. You can get the latest version at our github page.
Support via the sourceforge mailing list is still available, but you can also contact us in private ... always happy to help.
