+Changes since 1.1a1
+===================
+	* Most importantly, the distribution has been broken into two
+parts: exportable, and export-controlled.  The exportable part
+contains all the hashing algorithms, signature-only public key
+algorithms, chaffing & winnowing, random number generation, various
+utility modules, and the documentation.
+
+	The export-controlled part contains public-key encryption
+algorithms such as RSA and ElGamal, and bulk encryption algorithms
+like DES, IDEA, or Skipjack.  Getting this code still requires that
+you go through an access control CGI script, and denies you access if
+you're outside the US or Canada.
+
+	* Added the RIPEMD hashing algorithm.  (Contributed by
+Hirendra Hindocha.)
+
+	* Implemented the recently declassified Skipjack block
+encryption algorithm.  My implementation runs at 864 K/sec on a
+PII/266, which isn't particularly fast, but you're probably better off
+using another algorithm anyway.  :)
+
+	* A simple XOR cipher has been added, mostly for use by the
+chaffing/winnowing code.  (Contributed by Barry Warsaw.)
+
+	* Added Protocol.Chaffing and Hash.HMAC.py.  (Contributed by
+Barry Warsaw.)  
+
+	Protocol.Chaffing implements chaffing and winnowing, recently
+proposed by R. Rivest, which hides a message (the wheat) by adding
+many noise messages to it (the chaff).  The chaff can be discarded by
+the receiver through a message authentication code.  The neat thing
+about this is that it allows secret communication without actually
+having an encryption algorithm, and therefore this falls within the
+exportable subset.  
+
+	* Tidied up randpool.py, and removed its use of a block
+cipher; this makes it work with only the export-controlled subset
+available.
+
+	* Various renamings and reorganizations, mostly internal.
+	
+Changes since 1.0.2
+===================
+
+	* Changed files to work with Python 1.5; everything has been
+re-arranged into a hierarchical package.  (Not backward compatible.)
+The package organization is:
+Crypto.
+	Hash.
+		MD2, MD4, MD5, SHA, HAVAL
+	Cipher.
+		ARC2, ARC4, Blowfish, CAST, DES, DES3, Diamond, 
+		IDEA, RC5, Sapphire
+	PublicKey.
+		DSA, ElGamal, qNEW, RSA
+	Util.
+		number, randpool, RFC1751
+
+        Since this is backward-incompatible anyway, I also changed
+module names from all lower-case to mixed-case: diamond -> Diamond,
+rc5 -> RC5, etc.  That had been an annoying inconsistency for a while.
+	
+	* Added CAST5 module contributed by <wiml@hhhh.org>.
+
+        * Added qNEW digital signature algorithm (from the digisign.py
+I advertised a while back).  (If anyone would like to suggest new
+algorithms that should be implemented, please do; I think I've got
+everything that's really useful at the moment, but...)
+
+	* Support for keyword arguments has been added.  This allowed
+removing the obnoxious key handling for Diamond and RC5, where the
+first few bytes of the key indicated the number of rounds to use, and
+various other parameters.  Now you need only do something like:
+
+from Crypto.Cipher import RC5
+obj = RC5.new(key, RC5.ECB, rounds=8)
+
+(Not backward compatible.) 
+
+	* Various function names have been changed, and parameter
+names altered.  None of these were part of the public interface, so it
+shouldn't really matter much.
+
+	* Various bugs fixed, the test suite has been expanded, and
+the build process simplified.
+
+	* Updated the documentation accordingly.
+
+Changes since 1.0.1:
+====================
+	
+	* Changed files to work with Python 1.4 .
+
+	* The DES and DES3 modules now automatically correct the
+parity of their keys.
+	
+	* Added R. Rivest's DES test (see http://theory.lcs.mit.edu/~rivest/destest.txt)
+
+	Changes since 1.0.0:
+
+	* REDOC III succumbed to differential cryptanalysis, and has
+been removed. 
+
+	* The crypt and rotor modules have been dropped; they're still
+available in the standard Python distribution. 
+
+	* The Ultra-Fast crypt() module has been placed in a separate
+distribution; see <http://starship.skyport.net/crew/amk/maintained/crypto.html>.  
+
+	* Various bugs fixed.
