-Python-RSA changelog
-========================================
-
-Version 3.1.1 - in development
-----------------------------------------
-
-- Fixed doctests for Python 2.7
-- Removed obsolete unittest so all tests run fine on Python 3.2
-
-Version 3.1 - released 2012-06-17
-----------------------------------------
-
-- Big, big credits to Yesudeep Mangalapilly for all the changes listed
-  below!
-- Added ability to generate keys on multiple cores simultaneously.
-- Massive speedup
-- Partial Python 3.2 compatibility (core functionality works, but
-  saving or loading keys doesn't, for that the pyasn1 package needs to
-  be ported to Python 3 first)
-- Lots of bug fixes
-
-
-
-Version 3.0.1 - released 2011-08-07
-----------------------------------------
-
-- Removed unused import of abc module
-
-
-Version 3.0 - released 2011-08-05
-----------------------------------------
-
-- Changed the meaning of the keysize to mean the size of ``n`` rather than
-  the size of both ``p`` and ``q``. This is the common interpretation of
-  RSA keysize. To get the old behaviour, double the keysize when generating a
-  new key.
-  
-- Added a lot of doctests
-
-- Added random-padded encryption and decryption using PKCS#1 version 1.5
-
-- Added hash-based signatures and verification using PKCS#1v1.5
-
-- Modeling private and public key as real objects rather than dicts.
-
-- Support for saving and loading keys as PEM and DER files.
-
-- Ability to extract a public key from a private key (PEM+DER)
-
-
-Version 2.0
-----------------------------------------
-
-- Security improvements by Barry Mead.
