-according to the [Package Versioning Policy][pvp], the *de facto*
-standard Haskell versioning scheme.

-
-Changes to purely internal APIs are not included. Changes to internal
-APIs which are exposed through non-internal modules are detailed as if
-the change were made in the exposing module (eg, visible additions to
-Test.DejaFu.STM.Internal, such as a new typeclass instance, will show
-up as if they were added to Test.DejaFu.STM).
-
-Additions may be breaking changes as far as the PVP is concerned. For
-example, the addition of new data constructors, or new typeclass
-member functions.
