  OpenSSL CHANGES
  _______________
 
- Changes between 1.0.1e and 1.0.1f [xx XXX xxxx]
+ Changes between 1.0.1f and 1.0.1g [xx XXX xxxx]
 
-  *)
+  *) Fix for the attack described in the paper "Recovering OpenSSL
+     ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack"
+     by Yuval Yarom and Naomi Benger. Details can be obtained from:
+     http://eprint.iacr.org/2014/140
+
+     Thanks to Yuval Yarom and Naomi Benger for discovering this
+     flaw and to Yuval Yarom for supplying a fix (CVE-2014-0076)
+     [Yuval Yarom and Naomi Benger]
+
+  *) TLS pad extension: draft-agl-tls-padding-02
+
+     Workaround for the "TLS hang bug" (see FAQ and PR#2771): if the
+     TLS client Hello record length value would otherwise be > 255 and
+     less that 512 pad with a dummy extension containing zeroes so it
+     is at least 512 bytes long.
+
+     To enable it use an unused extension number (for example chrome uses
+     35655) using:
+
+     e.g. -DTLSEXT_TYPE_padding=35655
+
+     Since the extension is ignored the actual number doesn't matter as long
+     as it doesn't clash with any existing extension.
+
+     This will be updated when the extension gets an official number.

+
+ Changes between 1.0.1e and 1.0.1f [6 Jan 2014]
+
+  *) Fix for TLS record tampering bug. A carefully crafted invalid 
+     handshake could crash OpenSSL with a NULL pointer exception.
+     Thanks to Anton Johansson for reporting this issues.
+     (CVE-2013-4353)
+
+  *) Keep original DTLS digest and encryption contexts in retransmission
+     structures so we can use the previous session parameters if they need
+     to be resent. (CVE-2013-6450)
+     [Steve Henson]
+
+  *) Add option SSL_OP_SAFARI_ECDHE_ECDSA_BUG (part of SSL_OP_ALL) which
+     avoids preferring ECDHE-ECDSA ciphers when the client appears to be
+     Safari on OS X.  Safari on OS X 10.8..10.8.3 advertises support for
+     several ECDHE-ECDSA ciphers, but fails to negotiate them.  The bug
+     is fixed in OS X 10.8.4, but Apple have ruled out both hot fixing
+     10.8..10.8.3 and forcing users to upgrade to 10.8.4 or newer.
+     [Rob Stradling, Adam Langley]
