A new development release (2.7.6) of the Molecular Modelling Toolkit
is now available. There are various improvements and bug fixes:


- Allow unicode strings in filenames.

- New methods precedingResidue() and nextResidue() for peptide and
  nucleotide chains.

- NormalModes: use scipy.linalg if available, don't use symeig
  which is no longer maintained.

- Use PDB chain_id as name for nucleotide chains (just like for peptide
  chains) if segment_id is missing.

- Make read-only trajectories picklable (the pickle contains just the
  file name).

- Added database files for bromine and iodine.

Bug fixes:

- Strip spaces from chemical element names determined from a PDB file.

- Universe attributes of type string could cause MMTK to hang when
  updated or removed.

- Reading the trajectory variable box_size yielded a wrong result
  for trajectories with block_size > 1.
