CONTENTS
This newsletter marks the release of three new versions of the HDF software:
HDF5 1.8.0, HDF5 1.6.7, and HDF 4.2r3
HDF5 1.8.0 is a major release with file format changes, as well as many new features. The file format changes will affect backward/forward compatibility with previous releases. For detailed information on how this may affect your existing HDF5 applications and files, please read the document on "New Features in Release 1.8.0 and Format Compatibility Considerations":
https://support.hdfgroup.org/HDF5/doc/ADGuide/CompatFormat180.html
Not all users with existing applications will be willing or able to move to the HDF5 1.8.0 release because of these major changes. We are therefore continuing to support the HDF5 1.6 branch of HDF5. HDF5 1.6.7 is a point release with a few important changes, described below.
The HDF 4.2r3 release is also a point release with a few changes.

Release of HDF5 1.6.7
The latest release of HDF5 1.6, version 1.6.7, is now available from the HDF5 web page at:

Documentation for HDF5 1.6.7 can be found at:
https://support.hdfgroup.org/HDF5/doc1.6/
Changes in 1.6.7 include:
- The library's behavior has been changed when reading files that may have had corrupted object header information. By default, the library now rebuilds the correct object header information instead of issuing an error. The previous 'strict' file format interpretation can be enabled with the "--enable-strict-format-checks" configure option.
The stream I/O driver has been removed from the distribution.

Improvements to the configuration when building without NetCDF-3: The presence of the NetCDF-3 header files is no longer required to build the HDF4 library with the --without-netcdf configuration flag.
A fix for the problem where more than one variable has the same name. New APIs were added to handle non-uniquely named variables. (SDgetnumvars_byname, SDnametoindices)
