Soprano 2.3.1 is the first bugfix release for the 2.3 series and fixes a few little annoyances:
- Changed installation path of cmake modules (SopranoAppOntology.cmake) to prefix/share/soprano/cmake
- Prevent the redland backend to add one statement multiple times.
- Properly handle class names containing a dash '-' in onto2vocabularyclass.
- sopranocmd: Fail if trying to export a non-graph query.
Get and package it while it is hot.
