An interface is normally between dependent applications and the
library.  It would normally include enumerations, structures, classes,
and functions, or anything else which effects the library ABI.  If you
want to ensure that existing applications continue to execute using
the existing environment variables, you may choose to consider this to
be an interface change even though the ABI hasn't changed.
