        * Backward incompatible 'GOST3410Curve' initialization: all
          parameters are passed not as big-endian encoded binaries, but
          as integers
        * Backward incompatible change: 'gost3410.CURVE_PARAMS' is
          disappeared.  'gost3410.CURVES' dictionary holds already
          initialized 'GOST3410Curve'.  Just use
          'CURVES["id-tc26-gost-3410-12-512-paramSetA"]' instead of
          'GOST3410Curve(*CURVE_PARAMS["id-tc26-gost-3410-12-512-paramSetA"])'

*3.12*
        * Added mode argument to 'pygost.gost3410_vko.kek_34102012256',
          because 256-bit private keys can be used with that algorithm
          too.
        * Fix incorrect degree sanitizing in
          'pygost.gost3410.GOST3410Curve.exp' preventing using of
          'UKM=1' in 'pygost.gost3410_vko.kek_*' functions.

          vectors
        * 34.11-94 digest is reversed, to be compatible with HMAC and
          PBKDF2 test vectors describe in TC26 documents
        * 34.11-94 PBKDF2 test vectors added
        * 'gost3410.prv_unmarshal', 'gost3410.pub_marshal',
          'gost3410.pub_unmarshal' helpers added, removing the need of
          'x509' module at all
        * 'gost3410.verify' requires '(pubX, pubY)' tuple, instead of
          two separate 'pubX', 'pubY' arguments
        * 34.11-94 based PBKDF2 function added
