The main features of this release are:
- The graphics module has been largely rewritten.
- The io for molecular entities has been made more configurable by adding "IO profiles". IO Profiles let you fine-tune the exact behaviour of the IO. It can be made very strict for batch processing or very sloppy for interactive work. See http://www.openstructure.org/docs/1.1/io/profile/ for more details.
- The PDB reader now honors the "HET" records. The record is used to mark certain residues as ligands.
- The Python interface has been given a more "pythonic" feel by also exporting several of the getters and setters as Python properties.
