        * [CVE-2012-2417] Fix LP#985164: insecure ElGamal key generation.
          (thanks: Legrandin)

          In the ElGamal schemes (for both encryption and signatures), g is
          supposed to be the generator of the entire Z^*_p group.  However, in
          PyCrypto 2.5 and earlier, g is more simply the generator of a random
          sub-group of Z^*_p.

          The result is that the signature space (when the key is used for
          signing) or the public key space (when the key is used for encryption)
          may be greatly reduced from its expected size of log(p) bits, possibly
          down to 1 bit (the worst case if the order of g is 2).

          While it has not been confirmed, it has also been suggested that an
          attacker might be able to use this fact to determine the private key.

          Anyone using ElGamal keys should generate new keys as soon as 
practical.

        * Huge documentation cleanup (thanks: Legrandin).

        * Added more tests, including test vectors from NIST 800-38A
          (thanks: Legrandin)

        * Remove broken MODE_PGP, which never actually worked properly.
          A new mode, MODE_OPENPGP, has been added for people wishing to write
          OpenPGP implementations.  Note that this does not implement the full
          OpenPGP specification, only the "OpenPGP CFB mode" part of that
          specification.

error

        * Fix: Segfaults within error-handling paths

        * Fix: Block ciphers allow empty string as IV

        * Fix DevURandomRNG to work with Python3's new I/O stack.
          (thanks: Sebastian Ramacher)

        * Remove automagic dependencies on libgmp and libmpir, let the caller
          disable them using args.

        * Many other minor bug fixes and improvements (mostly thanks to 
Legrandin)
