Changes since release 8v0

• Removal of limits on the number of pseudo atoms, segments, the length of file names and most other strings, and the number of parameters in parameter files.

• Removal of the read_restyp() command. To read a user-defined residue type file, set restyp_lib_file when creating an environ object.

• Bug fix: the correct VDW radii (as selected by topology.submodel) are now used for PSA calculations (previously the all-hydrogen radii were used in all cases).

• Improved error handling: almost all errors should be recoverable now (using the standard Python exception handling mechanism) and incorrect input should trigger an error rather than causing Modeller to crash (please report any crashes as bugs to the developers).

• SALIGN bug fixes, improved binning of access classes.

• Modeller scripts are now more like 'real' Python scripts; the PYTHONPATH environment variable is honored, and additional command line arguments can be given to your scripts (accessible as sys.argv).

• Bug fix for alignment.segment_matching(): correct alignment scores are now written.

• Support for AMD64 and EM64T (Opteron/Xeon64) Linux machines.

• DOPE model assessment now returns only the DOPE energy itself by default, ignoring other energy terms.

• Bug fix for restraints.pick() when used with absolute position restraints; always allow 1-atom restraints to pass the residue_span_range check.
