-Upgrading from older versions
-==================================================
-
-Previous versions of Python-RSA were less secure than the current
-version. In order to be able to gradually upgrade your software, those
-old versions are still available.
-
-To use version 1.3.3, use this::
-
-    import rsa._version133 as rsa
-
-And to use version 2.0, use this::
-
-    import rsa._version200 as rsa
-
-You can import all three versions at the same time. This allows you to
-use an old version to decrypt your messages, and a new version to
-re-encrypt them::
-
-    import rsa._version200 as rsa200
-    import rsa                        # this imports version 3.0
-
-    decrypted = rsa200.decrypt(old_crypto, version_200_private_key)
-    new_crypto = rsa.encrypt(decrypted, version_3_public_key)
-
-Those import statements *will create warnings* as they import much
-less secure code into your project.
-
-The random padding introduced in version 3.0 made things much more
-secure, but also requires a larger key to encrypt the same message.
-You can either generate a new key with :py:func:`rsa.newkeys`, or use
-:py:func:`rsa.bigfile.encrypt_bigfile` to encrypt your files.
-
-Converting keys
---------------------------------------------------
-
-Version 3.0 introduced industrial standard RSA keys according to
-PKCS#1. The old keys were just dictionaries. To convert a key from an
-older version of Python-RSA, use the following::
-
-    import rsa
-
-    # Load the old key somehow.
-    old_pub_key = {
-        'e': 65537,
-        'n': 31698122414741849421263704398157795847591L
-    }
-
-    old_priv_key = {
-        'd': 7506520894712811128876594754922157377793L,
-        'p': 4169414332984308880603L,
-        'q': 7602535963858869797L
-    }
-
-    # Create new key objects like this:
-    pub_key = rsa.PublicKey(n=old_pub_key['n'], e=old_pub_key['e'])
-
-    priv_key = rsa.PrivateKey(n=old_pub_key['n'], e=old_pub_key['e'],
-        d=old_priv_key['d'], p=old_priv_key['p'], q=old_priv_key['q'])
-
-
-    # Or use this shorter notation:
-    pub_key = rsa.PublicKey(**old_pub_key)
-
-    old_priv_key.update(old_pub_key)
-    priv_key = rsa.PrivateKey(**old_priv_key)
-
