I was wondering if there were any planned updates in increasing the support for CGNS format? Some interesting open source software (like SU2, even though the SU2 format is supported by gmsh) use the CGNS file format and it is quite a portable / interesting /compact mesh format from our experience.

Koen Hillewaert (in CC) has been hard at work rewriting/improving CGNS support in Gmsh; you can follow his work by cloning the "cgnsUnstructured" branch in our git repo. He is probably the right person to answer your question...
