- An interactive mode has been added to IMP::domino::DominoSampler. The interactive mode is useful for understanding domino sampling runs and distributing domino comptutations across a cluster. - Functions IMP::domino::set_assignments() and IMP::domino::get_assignments() were added which support writing subset assignments to data fields in hdf5 files. These can be used to helping to distribute domino on a cluster as well as debugging the sampling process. - a python function IMP.show_graphviz() has been added that attempts to render a graph with \c dot and then open the pdf. - The python functions IMP.show_altgraph() and IMP.get_networkx_graph() have been added to provide alternatives for quick viewing of \imp graphs. Unfortunately, they still pale compared to graphviz. - IMP.atom.create_cover() was added to facilitate creating a summary particle for part of a hierarchy in order to accelerate restraints. - IMP.hdf5 was renamed to IMP.rmf, the proposed name of the file format that it supports. That also better separates the hdf5 support from the file format support. - The old I/O functions have been marked as deprecated in favor of IMP.hdf5. You may need to compile with deprecated="yes" if you use them. - The python graph interface now has a remove_vertex method.
