  Changes between 0.9.8a and 0.9.9  [xx XXX xxxx]
 
+  *) Disable rogue ciphersuites:
+
+      - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5")
+      - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5")
+      - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5")
+
+     The latter two were purportedly from
+     draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really
+     appear there.
+
+     Other ciphersuites from draft-ietf-tls-56-bit-ciphersuites-01.txt
+     remain enabled for now, but are just as unofficial, and the ID
+     has long expired; these will probably disappear soon.
+     [Bodo Moeller]
+
   *) Move code previously exiled into file crypto/ec/ec2_smpt.c
      to ec2_smpl.c, and no longer require the OPENSSL_EC_BIN_PT_COMP
      macro.
