C++ API:
--------
- Added overloaded functions read and write to H5::Attribute.
BMR - 2003/04/21
- Added an overloaded constructor H5::StrType so the need to separately
set the length of the string type can be eliminated. BMR - 2003/04/21
- Added overloaded functions read and write to H5::DataSet.
BMR - 2003/04/27
The following items were added but not documented in previous releases:
- On windows, any application, that uses the C++ API dll, must
include the name HDF5CPP_USEDLL in its project setting. (Feb 17, 2002)
BMR - 2003/10/10
- Added missing default constructor H5::H5File. (Apr 26, 2002)
BMR - 2003/10/10
- Added new member function H5::DataSet::fillMemBuf per the new C
API H5Dfill, which fills the elements in a selection for a memory
buffer with a fill value. (May 16, 2002) BMR - 2003/10/10
- Added the new member function getMemberIndex to H5::EnumType
and H5::CompType to match the new C API H5Tget_member_index. Given
the name of a member of an enumeration or compound datatype, this
new function queries the index of the member. (May 16, 2002)
BMR - 2003/10/10
- Added these member functions to H5::Group per the new C functions
H5Gget_num_objs, H5Gget_objname_by_idx and H5Gget_objtype_by_idx:
+ getNumObjs: Returns the number of objects in the group.
+ getObjnameByIdx: Retrieves the name of an object in a group,
given an index
+ getObjTypeByIdx: Returns the type of an object in a group,
given an index

Support for new platforms, languages and compilers.
=======================================
- gcc 3.3.1 is supported on Linux.

Bug Fixes since HDF5-1.6.1 release
==================================
Library
-------
- Fixed incorrect datatype of the third parameter to the Fortran90
h5pset(get)_cache_f functions (INTEGER to INTEGER(SIZE_T)) EIP - 2003/10/13
- Fixed problems with accessing variable-length data datatypes on
Crays. QAK - 2003/10/10
- Fixed potential file corruption bug when too many object header
messages (probably attributes, from a user perspective) were
inserted into an object header and certain other conditions were
met. QAK - 2003/10/08
- Changed implementation of internal ID searching algorithm to avoid
O(n) behavior for many common cases. QAK - 2003/10/06
- Allow partial parallel writing to compact datasets. QAK - 2003/10/06
- Correctly create reference to shared datatype in attribute, instead
of making a copy of the shared datatype in the attribute.
QAK - 2003/10/01
- Revert changes which caused files >2GB to fail when created with
MPI-I/O file driver on certain platforms. QAK - 2003/09/16
- Allow compound datatypes to grow in size. SLU - 2003/09/10
- Detect if a type is already packed before attempting to pack it
again or check if it is locked. SLU - 2003/09/10
- Corrected bug when opening a file twice with read-only permission
for one open and then closing the read-only access file ID would
generate an error. QAK - 2003/09/10
- Corrected bug in repeated calls to H5Pget_access_plist() which would
incorrectly manage reference counts of internal information and
eventually blow up. QAK - 2003/09/02
- Return rank of the array datatype on successful call to
H5Tget_array_dims(). QAK - 2003/08/30
- Corrected bug in H5Tdetect_class which was not correctly detecting
datatype classes of fields in nested compound datatypes in some
circumstances. QAK - 2003/08/30
- Corrected bug in sieve buffer code which could cause loss of data
when a small dataset was created and deleted in quick succession.
QAK - 2003/08/27
- Corrected bug in H5Gget_objname_by_idx which was not allowing NULL
for the name when just querying for the object name's length.
QAK - 2003/08/25
- Corrected bug in variable-length string handling which could
generate a core dump on writing variable-length strings as part
of a compound datatype on certain architectures. QAK - 2003/08/25
- Corrected bug in H5Tget_native_type which would incorrectly compute
the size of certain compound datatypes and also incorrectly
compute the offset of the last field for those compound datatypes.
QAK - 2003/08/25
- Corrected bug in H5Tget_native_type which would drop string datatype
metadata (padding, etc.) QAK - 2003/08/25
- Corrected bugs in H5Gget_num_objs, H5Gget_objname_by_idx and
H5Gget_objtype_by_idx to allow them to accept location IDs, not just
group IDs. QAK - 2003/08/21
- Corrected bug when using scalar dataspace for memory selection and
operating on chunked dataset. QAK - 2003/08/18
- Corrected bugs with multiple '/' characters in names for H5Glink
and H5Gunlink. QAK - 2003/08/16
- Corrected bug with user blocks that didn't allow a user block to
be inserted in front of a file after the file was created.
QAK - 2003/08/13
- Corrected errors with using point selections to access data in
chunked datasets. QAK - 2003/07/23
- Corrected error with variable-length datatypes and chunked datasets
which caused H5Dwrite to fail sometimes. QAK - 2003/07/19
- Modified library and file format to support storing indexed storage
(chunked dataset) B-tree's with non-default internal 'K' values.
QAK - 2003/07/15
- Returned H5T_BKG_TEMP support to library after it was accidentally
removed. QAK - 2003/07/14
- Fixed problems with MPI datatypes that caused ASCI Q machine to
hang. QAK - 2003/10/28
- Removed HDF5_MPI_PREFER_DERIVED_TYPES environment variable support,
since it had no benefit. QAK - 2003/10/28
- Single hyperslab selections (which were set with only one call to
H5Sselect_hyperslab) that had dimensions that could be "flattened"
but were interspersed with dimensions that could not be flattened
were not correctly handled, causing core dumps. QAK - 2003/10/25
- Avoid metadata cache from preempting current dataset object header
when looking up information about the named datatype that the
dataset uses. QAK - 2003/10/20
Configuration
-------------
- Fixed the error that caused "make install" to fail because of the
macro definition syntax of "prefix?=..." AKC - 2003/07/22
Performance
-------------
- Hoisted invariant 'if/else's out of inner datatype conversion loop for
integer and floating-point values, giving about a 20% speedup.
QAK - 2003/10/20
Tools
-----
- Fixed a segmentation fault of h5diff when percentage option is used.
AKC - 2003/08/27
- Switched away from tools using internal "fixtype" function(s) to use
H5Tget_native_type() internally. QAK - 2003/08/25
Documentation
-------------
- Added two missing Fortran APIs (h5pget_fapl_mpiposix_f and
h5pset_fapl_mpiposix_f) to the reference manual.
FMB - 2003/10/15
- Corrected the reference manual descriptions of H5open/h5open_f and
H5close/h5close_f to indicate that these calls are required in
Fortran90 applications. FMB - 2003/10/15
Documentation
=============
Fortran90 APIs are being integrated into the main body of the
HDF5 Reference Manual (RM). This process is complete in all RM sections
except H5P.
A PDF version of the RM will be posted on the HDF5 website
(at http://hdf.ncsa.uiuc.edu/HDF5/doc/PSandPDF/) approximately one week
after the release.
