  Changes between 0.9.3a and 0.9.4  [xx Aug 1999]
 
+  *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
+     program.
+     [Steve Henson]
+
   *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
      DH parameters/keys (q is lost during that conversion, but the resulting
      DH parameters contain its length).

+  Major changes between OpenSSL 0.9.3 and OpenSSL 0.9.4:
+
+      o Transparent support for PKCS#8 format private keys: these are used
+        by several software packages and are more secure than the standard form.
+      o PKCS#5 v2.0 implementation.
+
   Major changes between OpenSSL 0.9.2b and OpenSSL 0.9.3:
       o Lots of enhancements and cleanups to the Configuration mechanism
