+  *) Support for automatic EC temporary key parameter selection. If enabled
+     the most preferred EC parameters are automatically used instead of
+     hardcoded fixed parameters. Now a server just has to call:
+     SSL_CTX_set_ecdh_auto(ctx, 1) and the server will automatically
+     support ECDH and use the most appropriate parameters.
+     [Steve Henson]
+
   *) Enhance and tidy EC curve and point format TLS extension code. Use
      static structures instead of allocation if default values are used.
      New ctrls to set curves we wish to support and to retrieve shared curves.

+
+  *) Check for potentially exploitable overflows in asn1_d2i_read_bio
+     BUF_mem_grow and BUF_mem_grow_clean. Refuse attempts to shrink buffer
+     in CRYPTO_realloc_clean.

+     Thanks to Tavis Ormandy, Google Security Team, for discovering this
+     issue and to Adam Langley <agl@chromium.org> for fixing it.

+
+  *) Don't allow TLS 1.2 SHA-256 ciphersuites in TLS 1.0, 1.1 connections.
+     [Adam Langley]
+
+  *) Workarounds for some broken servers that "hang" if a client hello
+     record length exceeds 255 bytes:
+ 
+     1. Do not use record version number > TLS 1.0 in initial client
+        hello: some (but not all) hanging servers will now work.
+     2. If we set OPENSSL_MAX_TLS1_2_CIPHER_LENGTH this will truncate
+        the number of ciphers sent in the client hello. This should be
+        set to an even number, such as 50, for example by passing:
+        -DOPENSSL_MAX_TLS1_2_CIPHER_LENGTH=50 to config or Configure.
+        Most broken servers should now work.
+     3. If all else fails setting OPENSSL_NO_TLS1_2_CLIENT will disable
+        TLS 1.2 client support entirely.
 
   *) Fix SEGV in Vector Permutation AES module observed in OpenSSH.
