  Changes between 1.1.0h and 1.1.1 [xx XXX xxxx]
 
+  *) Revert blinding in ECDSA sign and instead make problematic addition
+     length-invariant. Switch even to fixed-length Montgomery multiplication.
+     [Andy Polyakov]
+
+  *) Use the new ec_scalar_mul_ladder scaffold to implement a specialized ladder
+     step for binary curves. The new implementation is based on formulas from
+     differential addition-and-doubling in mixed Lopez-Dahab projective
+     coordinates, modified to independently blind the operands.
+     [Billy Bob Brumley, Sohaib ul Hassan, Nicola Tuveri]
+
+  *) Add a scaffold to optionally enhance the Montgomery ladder implementation
+     for `ec_scalar_mul_ladder` (formerly `ec_mul_consttime`) allowing
+     EC_METHODs to implement their own specialized "ladder step", to take
+     advantage of more favorable coordinate systems or more efficient
+     differential addition-and-doubling algorithms.
+     [Billy Bob Brumley, Sohaib ul Hassan, Nicola Tuveri]
+
+  *) Modified the random device based seed sources to keep the relevant
+     file descriptors open rather than reopening them on each access.
+     This allows such sources to operate in a chroot() jail without
+     the associated device nodes being available. This behaviour can be
+     controlled using RAND_keep_random_devices_open().
+     [Paul Dale]
+
+  *) Numerous side-channel attack mitigations have been applied. This may have
+     performance impacts for some algorithms for the benefit of improved
+     security. Specific changes are noted in this change log by their respective
+     authors.
+     [Matt Caswell]
+
   *) AIX shared library support overhaul. Switch to AIX "natural" way of
      handling shared libraries, which means collecting shared objects of
      different versions and bitnesses in one common archive. This allows to

      Some of its new features are:
       o Support for multiple DRBG instances with seed chaining.
-      o Add a public DRBG instance for the default RAND method.
-      o Add a dedicated DRBG instance for generating long term private keys.
-      o Make the DRBG instances fork-safe.
+      o The default RAND method makes use of a DRBG.
+      o There is a public and private DRBG instance.
+      o The DRBG instances are fork-safe.
       o Keep all global DRBG instances on the secure heap if it is enabled.
-      o Add a DRBG instance to every SSL instance for lock free operation
-        and to increase unpredictability.
+      o The public and private DRBG instance are per thread for lock free
+        operation
