Configuration:
--------------
+ - HDF5 now uses automake 1.9.5 to generate Makefiles.in.
+ This has a number of effects on users:
+ The Fortran compiler should be set using the environment
+ variable $FC, not $F9X. F9X still works, but is depreciated.
+ The output of make may be different. This should be only a
+ cosmetic effect.
+ make depened (or make dep) is no longer recognized, since automake
+ handles dependency tracking.
+ Some new configure options exist. --enable-dependency-tracking
+ and --disable-dependency-tracking are used to control automake's
+ dependency tracking. Dependencies are on by default *on most
+ platforms and compilers*. If --enable-dependency-tracking is
+ used, they will be enabled on any platform. However, this can
+ slow down builds or even cause build errors in some cases.
+ Likewise, --disable-dependency-tracking can speed up builds and
+ avoid some build errors.
+ Some make targets have alternate names. make check-install and
+ make installcheck do the same thing, for instance.
+ pmake on IRIX can be invoked from the root directory, but the
+ -V flag must be used to invoke it in any subdirectory or it
+ will give an error about undefined variables.

Library:
--------
+ - HDF5 supports collective MPI-IO for irregular selection with HDF5
+ dataset. Irregular selection is when users use H5Sselect_hyperslab
+ more than once for the same dataset.
+ Currently, not all MPI-IO packages support complicated MPI derived
+ datatype used in the implementation of irregular
+ selection INSIDE HDF5.
+ DEC 5.x is not supporting complicated derived datatype.

+ - HDF5 N-bit filter
+ HDF5 support N-bit filter from this version,
+ The N-Bit filter is used effectively for compressing data of N-Bit

+ - HDF5 scaleoffset filter
+ HDF5 supports scaleoffset filter for users to do data
+ compression through HDF5 library.
+ Scale-Offset compression performs a scale and/or offset operation
+ on each data value and truncates the resulting value to a minimum
+ number of bits and then stores the data.
+ Currently only integer datatype
+ is supported. Please check the HDF5 reference manual for this.
