  Changes between 0.9.7c and 0.9.8  [xx XXX xxxx]
 
+  *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality.
+     This will generate a random key of the appropriate length based on the 
+     cipher context. The EVP_CIPHER can provide its own random key generation
+     routine to support keys of a specific form. This is used in the des and 
+     3des routines to generate a key of the correct parity. Update S/MIME
+     code to use new functions and hence generate correct parity DES keys.
+     Add EVP_CHECK_DES_KEY #define to return an error if the key is not 
+     valid (weak or incorrect parity).
+     [Steve Henson]
+
+  *) Add a local set of CRLs that can be used by X509_verify_cert() as well
+     as looking them up. This is useful when the verified structure may contain
+     CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs
+     present unless the new PKCS7_NO_CRL flag is asserted.
+     [Steve Henson]
+
+  *) Extend ASN1 oid configuration module. It now additionally accepts the
+     syntax:
+
+     shortName = some long name, 1.2.3.4
+     [Steve Henson]
+
+  *) Reimplemented the BN_CTX implementation. There is now no more static
+     limitation on the number of variables it can handle nor the depth of the
+     "stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack
+     information can now expand as required, and rather than having a single
+     static array of bignums, BN_CTX now uses a linked-list of such arrays
+     allowing it to expand on demand whilst maintaining the usefulness of
+     BN_CTX's "bundling".
+     [Geoff Thorpe]
+
   *) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD
      to allow all RSA operations to function using a single BN_CTX.
