Library
-------
+ - Fixed H5Giterate to avoid re-using index parameter after iteration
+ callback has been called (allows iteration callback to modify the
+ index parameter itself). QAK - 2003/12/06
- Fixed various floating-point conversion problems, including a
change which could corrupt data when converting from double->float.
QAK - 2003/11/24
