Changes since release 9.9

• Add Python 3 support.

• Add support for Mac OS X 10.7 (Lion).

• Modeller on 64-bit Macs is now built with Intel Fortran, resulting in a roughly 2x speedup compared to 9.9.

• Add Unicode support; all filenames should be UTF-8 encoded.

• CHARMM angle restraint on GLN OE1 and ASN OD1 atoms strengthened to avoid generating poor stereochemistry for these residues.

• Bugfix: atoms with undefined coordinates are assigned zero accessibility.

• Bugfix: selection.superpose() no longer fails if given residues containing multiple selected atoms with the same name.

• Bugfix: don't create empty .DLxxx files when loop modeling with automodel.trace_output set to 0.

• Bugfix: model.to_iupac() now correctly handles hydrogen atoms in Arg residues.

• Bugfix: fix a crash in alignment.write() with certain large alignments.

• Bugfix: set model.seq_id correctly when using a user-supplied initial model with automodel.

• Bugfix: don't force HSE and HSP residues to be ATOM; leave them as HETATM if they are so labeled in the input PDB.
