Release of HDF5-1.8.12

The HDF5-1.8.12 release is now available, and can be downloaded from the
HDF Group Downloads page:


It can also be obtained directly from:


HDF5-1.8.12 is a minor release, with a few new features and changes,

   o An option was added to specify the location of a default plugin
     (dynamically loaded filter) when building HDF5.

     The configure option is: --with-default-plugindir=location
     The CMake option is: -DH5_DEFAULT_PLUGINDIR:PATH=location

   o The h5repack utility was updated to use plugin filters (dynamically
     loaded filters) to read and write files.

   o The following options were added to h5dump:

     - The "-N" or "--any_path" option searches the file for paths that
       match the search path.

     - The "-A 0" option excludes the display of attributes.

   o Several changes were made to the C++ APIs. Some wrappers and
     overloaded convenience functions were added, as well as a new
     class, H5::H5Location.

This release contains many other changes that are not listed here.
Please be sure to read the Release Notes for a comprehensive list of
new features and changes:


Changes that affect maintainers of HDF5-dependent applications are

Future Changes to Supported Platforms

Please be aware that after this release we will be moving our current
standard for Windows from Windows 7 VS 2010 Intel Fortran 12 to
Windows 7 VS 2012 Intel Fortran 13. All versions will continue to be
tested but only pre-built binaries for VS 2012 Intel Fortran 13 will
be provided on the web site.

In addition, we plan to drop support for Mac OS X 10.6, move to
CMake 2.8.14, and upgrade the GNU Autotools to the latest version.

Let us know if you have any concerns about these upcoming changes.

Release of h4mapwriter version 1.0.6

Version 1.0.6 of the h4mapwriter utility is now available and can be
downloaded from the h4mapwriter project page:


The 1.0.6 release improves error handling of unmappable objects.

The h4mapwriter is a utility that creates an HDF4 file content map in
XML for a given HDF4 file. It enables the data to be retrieved from
an HDF4 file without relying on the HDF4 library.

Release of h5edit 1.2.0

Version 1.2.0 of h5edit is available from the JPSS project Downloads


New features in this release include:

   o Added support for the MODIFY command.
   o Added support for Mac OS X Mountain Lion 10.8.4.

The h5edit tool is a general command line tool to edit HDF5 files.
The current version is limited to operations on attributes only. For
