We're still not quite ready for the netcdf transition, but I'd like to
formally request the transition already anyway.
The automatically created auto-netcdf tracker is not sufficient to track
the new C++ & Fortran packages. I've attached the ben configuration I
used for my pkg-grass-transitions tracker in the preparation of this
transition.
For the libstdc++ transition we still need to update the symbols files
for the new netcdf packages in experimental. And there are couple of
reverse dependencies that FTBFS with the netcdf from experimental.
Please see the recent message on the debian-gis lists for more
information on the outstanding issues for the netcdf transition [1][2][3].
The biggest change in the netcdf transition is the split into language
specific packages that follow the upstream split into separate projects. [4]

netcdf-cxx provides the new NetCDF-4 C++ API in libnetcdf_c++4.so.1,
netcdf-cxx-legacy the legacy NetCDF-3 C++ API in libnetcdf_c++.so.4.
The netcdf-cxx-legacy package is provided for backward compatibility,
the 4.2 release includes no changes since the 4.1.3 release we're
transitioning away from.
All netcdf reverse depndencies that rely on the C++ API build
successfully after libnetcdf-cxx-legacy-dev is added to their build
dependencies.
Please refer to the transition summary below for the status of the most
recent rebuilds of the netcdf reverse dependencies.
