   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 0.9.6 and OpenSSL 0.9.7:

       o New library section OCSP.
       o Complete haul-over of the ASN.1 library section.

   Major changes between OpenSSL 0.9.6 and OpenSSL 0.9.6a:

       o Security fix: change behavior of OpenSSL to avoid using
         environment variables when running as root.
       o Security fix: check the result of RSA-CRT to reduce the
         possibility of deducing the private key from an incorrectly
         calculated signature.
       o Security fix: prevent Bleichenbacher's DSA attack.
       o Security fix: Zero the premaster secret after deriving the
         master secret in DH ciphersuites.
       o Reimplement SSL_peek(), which had various problems.
       o Compatibility fix: the function des_encrypt() renamed to
         des_encrypt1() to avoid clashes with some Unixen libc.
       o Bug fixes for Win32, HP/UX and Irix.
       o Bug fixes in BIGNUM, SSL, PKCS#7, PKCS#12, X.509, CONF and

       o Bug fixes in misc. openssl applications.

       o Add tighter checks of BIGNUM routines.
       o Shared library support has been reworked for generality.
