The tuple extension you heard about has been in netCDF since the last
release, about a year ago. It involved adding a few new interfaces:

   There are ... some new interfaces that can be used to write, read, and
   inquire about records, where a record may contain multiple variables of
   different types and shapes. Where before you had to access a record's
   worth of data using multiple calls, now you will be able to use a single
   call.

Hyperslabs are merely netCDF jargon for multidimensional orthogonal
cross-sections, which were generalized in the last release to permit
sub-sampling along one or more dimensions and mapping between the points of
the hyperslab and the memory locations of the corresponding values.
