SnapPy 1.7 is out. The main new feature is the ptolemy module for studying representations into PSL(*n*, **C**). This code was contributed by Mattias Görner, and is based on the the following two very interesting papers:

- Stavros Garoufalidis, Matthias Goerner, Christian K. Zickert: Gluing equations for PGL(n,C)-representations of 3-manifolds.
- Stavros Garoufalidis, Dylan P. Thurston, Christian K. Zickert: The complex volume of SL(n,C)-representations of 3-manifolds.

You can get the latest version of SnapPy at the usual place.
