  This file gives a brief overview of the major changes between each OpenSSL
  release. For more details please read the CHANGES file.

  Major changes between OpenSSL 0.9.8 and OpenSSL 0.9.8a:

      o Fix potential SSL 2.0 rollback, CAN-2005-2969
      o Extended Windows CE support

  Major changes between OpenSSL 0.9.7g and OpenSSL 0.9.8:

      o Major work on the BIGNUM library for higher efficiency and to
        make operations more streamlined and less contradictory.  This
        is the result of a major audit of the BIGNUM library.
      o Addition of BIGNUM functions for fields GF(2^m) and NIST
        curves, to support the Elliptic Crypto functions.
      o Major work on Elliptic Crypto; ECDH and ECDSA added, including
        the use through EVP, X509 and ENGINE.
      o New ASN.1 mini-compiler that's usable through the OpenSSL
        configuration file.
      o Added support for ASN.1 indefinite length constructed encoding.
      o New PKCS#12 'medium level' API to manipulate PKCS#12 files.
      o Complete rework of shared library construction and linking
        programs with shared or static libraries, through a separate
        Makefile.shared.
      o Rework of the passing of parameters from one Makefile to another.
      o Changed ENGINE framework to load dynamic engine modules
        automatically from specifically given directories.
      o New structure and ASN.1 functions for CertificatePair.
      o Changed the ZLIB compression method to be stateful.

        mechanism to take a structure that contains the ticker
        function and an argument.
      o New engine module: GMP (performs private key exponentiation).
      o New engine module: VIA PadLOck ACE extension in VIA C3
        Nehemiah processors.

        constraints and name constraints.

        configuration file.

        sorts of data repositories.  Supports storage of public and
        private keys, certificates, CRLs, numbers and arbitrary blobs.

	OpenSSL.

        affected functions.
