Day 5 was formally the last day (see also the summaries of day 1, day 2 and day 3/4) of the Chemistry Development Kit Bug Squash Party (BSP). Miguel uploaded the last bits of his CDK PDBPolymer to CML to CDK PDBPolymer roundtripping functionality (closing a bug and a feature request in one go). Have not tested this first hand yet, but looking forward to playing with this bit of code.
