+@item GNU-style archiving has had an overhaul, and the GNUstep
+NSArchiver class is functional, but not strongly tested.
+
+I have separated the high-level archiving of groups of objects from the
+low-level format of how C-types are written.  There are several new
+classes.  CStream is a subclass of Stream that knows how to encode
+C-type variables in a machine independent way; this class has two
+concrete subclasses: BinaryCStream, and TextCStream.  Plug these
+backends into Coder to get different style low-level formats for
+archiving.
+
+NSArchiver is built on top of Coder.  You can actually send all the
+Coder methods to NSArchiver and vice-versa.
+
+GNU classes BinaryCoder and TextCoder are gone.
