New Features
Configuration:
Enforce the HDF5 version >= 1.8 is used in building HDF5. (CGNS-150).
Autotools: CGNS will find and link the compression libraries, szip and zlib, required by HDF5. This
occurs automatically if neither --with-zlib or --with-szip are not specified (CGNS-156).
Library:
Changed default CGNS to 1.8 HDF5 file format.
-- only for HDF5 versions > 1.10.2.
CPEX 40 Rind Plane Indexing (CGNS-87)
CPEX 41 NGON modification proposal (CGNS-121)
Parallel Library:
None
Fortran Library:
Added support for NAG Fortran compilers (CGNS-107)
Tools:
None

Known Problems
When building with PGI and gcc compilers it might be necessary to set the
environment variables:
FLIBS="-Wl,--no-as-needed -ldl"
LIBS="-Wl,--no-as-needed -ldl"
