  OpenSSL CHANGES
  _______________
 
- Changes between 0.9.8b and 0.9.9  [xx XXX xxxx]
+ Changes between 0.9.8e and 0.9.9  [xx XXX xxxx]
+
+  *) Load error codes if they are not already present instead of using a
+     static variable. This allows them to be cleanly unloaded and reloaded.
+     Improve header file function name parsing.
+     [Steve Henson]
+
+  *) Initial incomplete changes to avoid need for function casts in OpenSSL
+     when OPENSSL_NO_FCAST is set: some compilers (gcc 4.2 and later) reject
+     their use. Safestack is reimplemented using inline functions: tests show
+     that these calls are typically optimized away by compilers so they have
+     no additional overhead. Update ASN1 to avoid use of legacy functions. 
+     [Steve Henson]
+
+  *) Win32/64 targets are linked with Winsock2.
+     [Andy Polyakov]
+
+  *) Add an X509_CRL_METHOD structure to allow CRL processing to be redirected
+     to external functions. This can be used to increase CRL handling 
+     efficiency especially when CRLs are very large by (for example) storing
+     the CRL revoked certificates in a database.
+     [Steve Henson]
+
+  *) Overhaul of by_dir code. Add support for dynamic loading of CRLs so
+     new CRLs added to a directory can be used. New command line option
+     -verify_return_error to s_client and s_server. This causes real errors
+     to be returned by the verify callback instead of carrying on no matter
+     what. This reflects the way a "real world" verify callback would behave.
+     [Steve Henson]
+
+  *) GOST engine, supporting several GOST algorithms and public key formats.
+     Kindly donated by Cryptocom.
+     [Cryptocom]
+
+  *) Partial support for Issuing Distribution Point CRL extension. CRLs
+     partitioned by DP are handled but no indirect CRL or reason partitioning
+     (yet). Complete overhaul of CRL handling: now the most suitable CRL is
+     selected via a scoring technique which handles IDP and AKID in CRLs.
+     [Steve Henson]
+
+  *) New X509_STORE_CTX callbacks lookup_crls() and lookup_certs() which
+     will ultimately be used for all verify operations: this will remove the
+     X509_STORE dependency on certificate verification and allow alternative
+     lookup methods.  X509_STORE based implementations of these two callbacks.
+     [Steve Henson]
+
+  *) Allow multiple CRLs to exist in an X509_STORE with matching issuer names.
+     Modify get_crl() to find a valid (unexpired) CRL if possible.
+     [Steve Henson]
+
+  *) New function X509_CRL_match() to check if two CRLs are identical. Normally
+     this would be called X509_CRL_cmp() but that name is already used by
+     a function that just compares CRL issuer names. Cache several CRL 
+     extensions in X509_CRL structure and cache CRLDP in X509.
+     [Steve Henson]
+
+  *) Store a "canonical" representation of X509_NAME structure (ASN1 Name)
+     this maps equivalent X509_NAME structures into a consistent structure.
+     Name comparison can then be performed rapidly using memcmp().
+     [Steve Henson]
 
   *) Non-blocking OCSP request processing. Add -timeout option to ocsp 
      utility.

+     [Steve Henson, Bodo Moeller]
+

+     (CVE-2006-3738) [Tavis Ormandy and Will Drewry, Google Security Team]
+

+     malicious SSLv2 server.  (CVE-2006-4343)
+     [Tavis Ormandy and Will Drewry, Google Security Team]
+
+  *) Since 0.9.8b, ciphersuite strings naming explicit ciphersuites
+     match only those.  Before that, "AES256-SHA" would be interpreted
+     as a pattern and match "AES128-SHA" too (since AES128-SHA got
+     the same strength classification in 0.9.7h) as we currently only
+     have a single AES bit in the ciphersuite description bitmap.
+     That change, however, also applied to ciphersuite strings such as
+     "RC4-MD5" that intentionally matched multiple ciphersuites --
+     namely, SSL 2.0 ciphersuites in addition to the more common ones
+     from SSL 3.0/TLS 1.0.
+
+     So we change the selection algorithm again: Naming an explicit
+     ciphersuite selects this one ciphersuite, and any other similar
+     ciphersuite (same bitmap) from *other* protocol versions.
+     Thus, "RC4-MD5" again will properly select both the SSL 2.0
+     ciphersuite and the SSL 3.0/TLS 1.0 ciphersuite.
+
+     Since SSL 2.0 does not have any ciphersuites for which the
+     128/256 bit distinction would be relevant, this works for now.
+     The proper fix will be to use different bits for AES128 and
+     AES256, which would have avoided the problems from the beginning;
+     however, bits are scarce, so we can only do this in a new release
+     (not just a patchlevel) when we can change the SSL_CIPHER
+     definition to split the single 'unsigned long mask' bitmap into
+     multiple values to extend the available space.
