 Changes between 0.9.8a and 0.9.9  [xx XXX xxxx]





  *) New candidate for BIGNUM assembler implementation, bn_mul_mont,

     dedicated Montgomery multiplication procedure, is introduced.

     BN_MONT_CTX is modified to allow bn_mul_mont to reach for higher

     "64-bit" performance on certain 32-bit targets.

     [Andy Polyakov]



  *) New option SSL_OP_NO_COMP to disable use of compression selectively

  *) New option SSL_OP_NO_COMP to disable use of compression selectively

     in SSL structures. New SSL ctrl to set maximum send fragment size.
