  _______________
 
  Changes between 0.9.8r and 0.9.8s [xx XXX xxxx]
+ 
+  *) Prevent malformed RFC3779 data triggering an assertion failure.
+     Thanks to Andrew Chi, BBN Technologies, for discovering the flaw
+     and Rob Austein <sra@hactrn.net> for fixing it. (CVE-2011-4577)
+     [Rob Austein <sra@hactrn.net>]
+
+  *) Fix ssl_ciph.c set-up race.
+     [Adam Langley (Google)]
+
+  *) Fix spurious failures in ecdsatest.c.
+     [Emilia Käsper (Google)]
+
+  *) Fix the BIO_f_buffer() implementation (which was mixing different
+     interpretations of the '..._len' fields).
+     [Adam Langley (Google)]
+
+  *) Fix handling of BN_BLINDING: now BN_BLINDING_invert_ex (rather than
+     BN_BLINDING_invert_ex) calls BN_BLINDING_update, ensuring that concurrent
+     threads won't reuse the same blinding coefficients.
+
+     This also avoids the need to obtain the CRYPTO_LOCK_RSA_BLINDING
+     lock to call BN_BLINDING_invert_ex, and avoids one use of
+     BN_BLINDING_update for each BN_BLINDING structure (previously,
+     the last update always remained unused).
+     [Emilia Käsper (Google)]
 
   *) Fix SSL memory handling for (EC)DH ciphersuites, in particular
      for multi-threaded use of ECDH.
