The above functions will eventually be removed from the HDF5 distribution and from the HDF5 Reference Manual.
H5FDflush and VFL "flush" callbacks
closing has been added to
these functions,
to allow the library to indicate that the file will be closed
following the call to "flush". Actions in the "flush" call
that are duplicated in the VFL "close" call may be omitted by
the VFL driver.
H5Gget_objtype_by_idx
int to
the enumerated type H5G_obj_t.
H5Pset(get)_buffer
size parameter for H5Pset_buffer
has changed from type hsize_t to
size_t.
H5Pget_buffer return type has similarly
changed from hsize_t to
size_t.
H5Pset(get)_cache
rdcc_nelmts parameter has changed from type
int to
size_t.
H5Pset_fapl_log
verbosity parameter has been removed.
flags of type unsigned and
buf_size of type size_t.
H5Pset(get)_fapl_mpiposix
use_gpfs parameter of type
hbool_t has been added.
H5Pset(get)_sieve_buf_size
size parameter has changed from type
hsize_t to
size_t.
H5Pset(get)_sym_k
lk parameter has changed from type
int to
unsigned.
H5Sget_select_bounds
start and end parameters have
changed from type hsize_t *
to hssize_t * to better match the
rest of the dataspace API.
H5Zregister
H5Z_class_t struct and
new set local and can apply callback functions.
h5pset(get)_fapl_core_f
backing_store parameter has changed from
INTEGER to LOGICAL
to better match the C API.
h5pset(get)_preserve_f
flag parameter has changed from
INTEGER to LOGICAL
to better match the C API.
Backward compatibility with the Release 1.4.x syntax is available
for the functions indicated above with a leading asterisk (*).
The backward compatibility features are available only when the
HDF5 library is configured with the flag
H5_WANT_H5_V1_4_COMPAT,
is not enabled in the binaries distributed by NCSA, and
will eventually be removed from the HDF5 distribution.

Previously, the Communicator and Info object arguments supplied
to H5Pset_fapl_mpio were stored in the property with
its handle values.
This meant changes to the communicator or the Info object
after calling H5Pset_fapl_mpio would affect the how
the property list functioned.
This was also the case when H5Fopen/create operated.
They just stored the handle value. This is not according to the
MPI-2 defined behavior of how Info objects should be handled.
(MPI-2 defines Info objects must be parsed when called.)H5Pset_fapl_mpio now stores a duplicate of each of
the communicator and Info object.H5Pget_fapl_mpio now returns a duplicate of its
stored communicator and Info object.
It is now the responsibility of the applications to free
those objects when done.
Advice to users: User applications should release the communicator and
Info object returned by |

h5dwrite_f, h5dread_f, h5awrite_f, h5aread_f were overloaded
with dims argument to be assumed size array of type INTEGER(HSIZE_T).
We recommend to use the subroutines with the new type. Module subroutines
that accept dims as INTEGER array of size 7 will be deprecated in the 1.6.0 release.
