It can be downloaded from The HDF Group Downloads page: https://www.hdfgroup.org/downloads/ It can also be obtained from: https://www.hdfgroup.org/HDF5/release/obtain5.html HDF5-1.8.17 is a minor release with a few new features and changes. Important changes include: o Improvements were made to the High Level C and C++ Packet Table APIs, including: - The H5PTcreate function was added to provide control over creation properties. It replaces the H5PTcreate_fl function. The corresponding change in C++ is the addition of a new overloaded constructor to FL_PacketTable that takes a property list identifier. - H5PTget_dataset was added to return the identifier of the dataset associated with a packet table. The corresponding member function added for C++ is PacketTable::GetDataset(). - H5PTget_type was added to return the identifier of the datatype used by a packet table. The corresponding member function added for C++ is PacketTable::GetDatatype(). - C++ member functions with "char*" as an argument now include overloaded functions to provide a "const char*" argument. - The source code was cleaned up to remove the obsolete variable length packet table code. This included the following changes: o H5PTis_varlen() was made available again. The corresponding C++ function VL_PacketTable::IsVariableLength() was moved to PacketTable. o H5PTfree_vlen_readbuff() was renamed H5PTfree_vlen_buff(). The corresponding C++ function VL_PacketTable::FreeReadBuff() was renamed to PacketTable::FreeBuff(). o The H5Pset/get_efile_prefix() functions were added for controlling the search path for dataset external storage that has been configured with H5Pset_external(). Additionally, the HDF5_EXTFILE_PREFIX environment variable was added to control the search path. o The following new member functions were added to C++: - DSetCreatPropList::setNbit() sets up N-bit compression for a dataset. - New overloaded "const" member functions were added to ArrayType: ArrayType::getArrayNDims() const and ArrayType::getArrayDims() const o Overloaded C++ methods with parameters that were not "const" (but should have been) were removed. o Support was added for Mac OS X 10.11.4 (El Capitan).
