+  *) An audit of the BIGNUM code is underway, for which debugging code is
+     enabled when BN_DEBUG is defined. This makes stricter enforcements on what
+     is considered valid when processing BIGNUMs, and causes execution to
+     assert() when a problem is discovered. If BN_DEBUG_RAND is defined,
+     further steps are taken to deliberately pollute unused data in BIGNUM
+     structures to try and expose faulty code further on. For now, openssl will
+     (in its default mode of operation) continue to tolerate the inconsistent
+     forms that it has tolerated in the past, but authors and packagers should
+     consider trying openssl and their own applications when compiled with
+     these debugging symbols defined. It will help highlight potential bugs in
+     their own code, and will improve the test coverage for OpenSSL itself. At
+     some point, these tighter rules will become openssl's default to improve
+     maintainability, though the assert()s and other overheads will remain only
+     in debugging configurations. See bn.h for more details.

   *) BN_CTX_init() has been deprecated, as BN_CTX is an opaque structure
      that can only be obtained through BN_CTX_new() (which implicitly
      initialises it). The presence of this function only made it possible

  Changes between 0.9.7c and 0.9.7d  [xx XXX XXXX]
+
+  *) When creating an OCSP nonce use an OCTET STRING inside the extnValue.
+     A clarification of RFC2560 will require the use of OCTET STRINGs and 
+     some implementations cannot handle the current raw format. Since OpenSSL
+     copies and compares OCSP nonces as opaque blobs without any attempt at
+     parsing them this should not create any compatibility issues.

+  *) New md flag EVP_MD_CTX_FLAG_REUSE this allows md_data to be reused when
+     calling EVP_MD_CTX_copy_ex() to avoid calling OPENSSL_malloc(). Without
+     this HMAC (and other) operations are several times slower than OpenSSL
+     < 0.9.7.
