===
	* [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.

	  Any additional information about this bug will be tracked at
	  https://bugs.launchpad.net/pycrypto/+bug/985164

	* 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.

	* Fix: getPrime with invalid input causes Python to abort with fatal error
	  https://bugs.launchpad.net/pycrypto/+bug/988431

	* Fix: Segfaults within error-handling paths
	  (thanks: Paul Howarth & Dave Malcolm)

	* Fix: Block ciphers allow empty string as IV
	  https://bugs.launchpad.net/pycrypto/+bug/997464

	* 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)
