-	  older than 2.2.

-	  and changing the interface.
-	  
-	* (Backwards incompatible) Changed the function names in
-	  Crypto.Util.RFC1751.

-	* Restored the Crypto.PublicKey package at user request.  I
-	  think I'll leave it in the package and warn about it in the
-	  documentation.  I hope that eventually I can point to
-	  someone else's better public-key code, and at that point I
-	  may insert warnings and begin the process of deprecating
-	  this code.
-
-	* Fix use of a Python 2.2 C function, replacing it with a 
-	  2.1-compatible equivalent.  (Bug report and patch by Andrew
-	  Eland.)

-	* Fix endianness bugs that caused test case failures on Sparc,
