Future Versions

Version 1.080827 (September 26, 2008)

1. The C-language code for YUP has been completely revised for Python 2.5. The code does not use features that will not appear in future versions of the interpreter; thus YUP can no longer work with older versions of Python.
   
2. Revisions to the Atom Vector File format to encode length fields as standard integers. Atom Vector files created in previous versions of YUP on 64-bit operating environments are now incorrect. Unfortunately, there is no way to rescue those files.
3. Yup.test has been revised to run a comprehensive test in shorter time. It can also be used to run two standard benchmarks. Online documentation for Yup.scx and Yup.avf have been revised.
   

Version 1.080626 (June 27, 2008)

1. Available for 64-bit LINUX on x86_64.

Version 1.080601 (June 16, 2008)

1. A new force field term, Hand, is now available. It is similar to Impropers except that the equilibrium torsion angle is specified individually for each interaction.
2. Although the elastic network used in Yup.scx is not handed, it is now possible to impose chiral constraints, using the new Hand term.
   

Version 1.080101 (January 2, 2008)

1. Yup.avf, formerly a C-language program, has been re-implemented in Python.
   
2. The AtomVector file is now in single precision, halving the size of trajectory files.
   

Version 1.071130 (December 4, 2007)

1. Extensive revisions to the Emmental module, force-field parameters, and to Yup.scx.
2. First restricted version.
   

Version 1.070301 (March 2, 2007)

1. Contains corrections to the Emmental module.
   

Version 1.061201 (December 15, 2006)

1. This is the release that supports the Intel version of MacOS X.
2. New script Yup.scx.

Version 1.060901 (August 31, 2006)

1. SwissCheeseX is a new force field term that replaces the VLAT term from Yammp 1.
2. User updates in all molecular mechanics methods
3. The LIMIT attribute for Model objects
4. New toolbox for force field assembly, to replace packages in Tools eventually
5. The Emmental subpackage
6. The ChemNames module
   

Version 1.060604 (June 5, 2006)

1. All the keywords that were going to be supported in the Brookhaven module have been implemented.
2. Hooke is a new force field term.
3. You can now address your questions to an email address listed in the "Installation Manual".
   

Version 1.060401 (May 1, 2006)

1. The set_Temperature method of the Motors class in the Yup.Methods.MolDynam module has been revised to allow the random number generator to be seeded. Molecular Dynamics.
2. Yup.avf is a new program to convert an AtomVector file (AVF) to a text dump and back. AtomVector Files.
3. The utility module Yup.Tools.AVRecords now accepts the name of a single AVF file or a list of files.
4. The limit argument in molecular mechanics methods now accepts an atom number range.
5. Yup.Tools.Brookhaven is a new module that provides for the conversion between YUP models and PDB files in either direction.
