HDF5 1.8.7 is a minor release, but contains a few important new features
and bug fixes. Changes in this release include the following:
- The ability to cache files opened through external links was added to the
library. See the new functions, H5Pset_elink_file_cache_size(),
H5Pget_elink_file_cache_size(), and H5Fclear_elink_file_cache().
- Shared C++ and High Level libraries can now be built on AIX.
- The library now allows a dataspace dimension size to be zero. In the
past, the library only allowed this if the maximum dimension size was
unlimited. There is no longer this restriction, but data cannot be
written to this kind of dataset.
- Many improvements were made to the tools, particularly h5dump, h5diff,
h5ls, and h5copy. A few important changes include:
o A new "verbose with levels" option, '-vN, --verbose=N', was added
to h5diff.
o Improvements were made to the h5diff performance.
o Improvements were made with how h5diff compares attributes.
o The h5copy utility was fixed to enable copying an object into
the same HDF5 file.
- A few fixes were made to the High Level Fortran APIs.
This release contains many other changes not listed here. Please be sure to
