2. Given #1, then the NC_PNETCDF mode flag becomes a subset of NC_MPIIO, so made NC_PNETCDF an alias for NC_MPII.
3. NC_FORMAT_64BIT is now deprecated. Use NC_FORMAT_64BIT_OFFSET.
Further information regarding the CDF-5 file format specifrication may be found here: http://cucis.ece.northwestern.edu/projects/PnetCDF/CDF-5.html

2. --disable-parallel4 to be used when we do not want
netcdf-4 to use parallelism even if hdf5 has it enabled.
* Deprecating various extended format flags.
The various extended format flags of the format `NC_FORMAT_FOO` have been refactored into the form `NC_FORMATX_FOO`. The old flags still exist but have been marked as deprecated and will be removed at some point. This was done to avoid confusion between the extended format flags and the format flags `NC_FORMAT_CLASSIC`, `NC_FORMAT_64BIT_OFFSET`, etc. The mapping of deprecated-to-new flags is as follows:
Deprecated | Replaced with
-----------|-------------
NC\_FORMAT\_NC3 | NC\_FORMATX\_NC3
NC\_FORMAT\_NC\_HDF5 | NC\_FORMATX\_NC\_HDF5
NC\_FORMAT\_NC4 | NC\_FORMATX\_NC4
NC\_FORMAT\_NC\_HDF4 | NC\_FORMATX\_NC\_HDF4
NC\_FORMAT\_PNETCDF | NC\_FORMATX\_PNETCDF
NC\_FORMAT\_DAP2 | NC\_FORMATX\_DAP2
NC\_FORMAT\_DAP4 | NC\_FORMATX\_DAP4
NC\_FORMAT\_UNDEFINED | NC\_FORMATX\_UNDEFINED
* Reduced minimum cmake version to `2.8.11` from `2.8.12`. This will allow for cmake use on a broader set of popular linux platforms without having to do a custom cmake install. See https://github.com/Unidata/netcdf-c/issues/135 for more information.
* The documentation section `The Default Chunking Scheme` has been updated with more information. This lives in the `guide.dox` file in the `docs/` directory, or can be found online in the appropriate location (typically http://www.unidata.ucar.edu/netcdf/docs), once this release has been published.
