Configuration:
--------------
+ - Added some initial support for making purify (or similar memory
+ checking products) happier by initializing buffers to zero and
+ disabling the internal free list code. To take advantage of this,
+ define 'H5_USING_PURIFY' in your CFLAGS when building the library.
+ QAK - 2004/07/23
- Fixed the long compile time of H5detect.c when v7.x Intel Compiler
- is used with optimization NOT off. AKC - 2004/05/20
+ is used with optimization NOT off. AKC - 2004/05/20
- Fixed configure setting of C++ for OSF1 platform. AKC - 2004/01/06
- Prefix default is changed from /usr/local to `pwd`/hdf5.

Library:
--------
- 4 new API functions, H5Tencode, H5Tdecode, H5Sencode, H5Sdecode were
- added to the library. Given object ID, these functions encode and
- decode HDF5 objects(data type and space) information into and from
- binary buffer. SLU - 2004/07/21
+ added to the library. Given object ID, these functions encode and
+ decode HDF5 objects(data type and space) information into and from
+ binary buffer. SLU - 2004/07/21
- Modified the way how HDF5 calculates 'pixels_per_scanline' parameter for
- SZIP compression. Now there is no restriction on the size and shape of the
- chunk except that the total number of elements in the chunk cannot be
- bigger than 'pixels_per_block' parameter provided by the user.

- SZIP always uses K13 compression. This flag no longer needs to
- be set when calling H5Pset_szip. If the flag for CHIP
- compression is set, it will be ignored (since the two are mutually
- exclusive). JL/NF - 2004/6/30

of the file by object(file, group, data set, named data type,
attribute) ID. SLU - 2004/06/29
