  Changes between 0.9.4 and 0.9.5  [xx XXX 1999]
 
+  *) Add various functions that can check a certificate's extensions
+     to see if it usable for various purposes such as SSL client,
+     server or S/MIME and CAs of these types. This is currently 
+     VERY EXPERIMENTAL but will ultimately be used for certificate chain
+     verification. Also added a -purpose flag to x509 utility to
+     print out all the purposes.
+     [Steve Henson]
+
+  *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
+     functions.
+     [Steve Henson]
+
+  *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
+     for, obtain and decode and extension and obtain its critical flag.
+     This allows all the necessary extension code to be handled in a
+     single function call.
+     [Steve Henson]
+
+  *) RC4 tune-up featuring 30-40% performance improvement on most RISC
+     platforms. See crypto/rc4/rc4_enc.c for further details.
+     [Andy Polyakov]
+
+  *) New -noout option to asn1parse. This causes no output to be produced
+     its main use is when combined with -strparse and -out to extract data
+     from a file (which may not be in ASN.1 format).
+     [Steve Henson]
+
+  *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
+     when producing the local key id.
+     [Richard Levitte <levitte@stacken.kth.se>]
+
+  *) New option -dhparam in s_server. This allows a DH parameter file to be
+     stated explicitly. If it is not stated then it tries the first server
+     certificate file. The previous behaviour hard coded the filename
+     "server.pem".
+     [Steve Henson]
+
+  *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
+     a public key to be input or output. For example:
+     openssl rsa -in key.pem -pubout -out pubkey.pem
+     Also added necessary DSA public key functions to handle this.
+     [Steve Henson]
+
   *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
      in the message. This was handled by allowing
      X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
