     This file describes changes introduced into XMDF with each release.
     
     Note that VisualStudio 8 is required for building, Fortran is
     required for some builds, Doxygen is required for some builds to
     recreate documentation.  Release DLLs are provided pre-built.

Changes since 20December2005 to XMDF version 1.2

\\\\\\\\\\\\\
NEW FEATURES:
\\\\\\\\\\\\\
Upgraded for compatibility to HDF5 version 1.6.5.  This version of XMDF should not be used with older versions of HDF5.

Added timestep deletion. Added the function xfSetDatasetNumTimes to override the actual number of timesteps stored in the file.

Added a reference directory of test output files.


\\\\\\\\\\
BUG FIXES:
\\\\\\\\\\

The library was designed to use 1 based indices.  The following functions were using 0 based indices and have been converted to 1 based indices:
xfReadScalarValuesTimestep
xfReadActivityTimestep
xfReadScalarValuesAtIndex
xfReadVectorValuesTimestep
xfReadActivityValuesAtIndex

It seems there was a change to how HDF5 treats the function H5Topen.  Accordingly the following functions were changed.  This should not impact library users.
xfGetLibraryVersion
xfGetPropertyStringLength
xfReadPropertyString

Changed the Fortran versions of xfReadActivityTimestep, xfReadActivityValuesAtIndex, and xfReadVectorValuesAtIndex to translate correctly from 1 based to 0 based array indices.

Changed various Fortran function arguments from OUT to IN.

Changed char* conversions from Fortran functions to terminate the strings using the Fortran string length argument.
