  Changes between 1.0.1 and 1.1.0  [xx XXX xxxx]
 
+  *) Minor change to DRBG entropy callback semantics. In some cases
+     there is no mutiple of the block length between min_len and
+     max_len. Allow the callback to return more than max_len bytes
+     of entropy but discard any extra: it is the callback's responsibility
+     to ensure that the extra data discarded does not impact the
+     requested amount of entropy.
+     [Steve Henson]
+
+  *) Add PRNG security strength checks to RSA, DSA and ECDSA using 
+     information in FIPS186-3, SP800-57 and SP800-131A.
+     [Steve Henson]
+
+  *) CCM support via EVP. Interface is very similar to GCM case except we
+     must supply all data in one chunk (i.e. no update, final) and the
+     message length must be supplied if AAD is used. Add algorithm test
+     support.
+     [Steve Henson]
+
+  *) Initial version of POST overhaul. Add POST callback to allow the status
+     of POST to be monitored and/or failures induced. Modify fips_test_suite
+     to use callback. Always run all selftests even if one fails.
+     [Steve Henson]
+
+  *) XTS support including algorithm test driver in the fips_gcmtest program.
+     Note: this does increase the maximum key length from 32 to 64 bytes but
+     there should be no binary compatibility issues as existing applications
+     will never use XTS mode.
+     [Steve Henson]
+
+  *) Extensive reorganisation of FIPS PRNG behaviour. Remove all dependencies
+     to OpenSSL RAND code and replace with a tiny FIPS RAND API which also
+     performs algorithm blocking for unapproved PRNG types. Also do not
+     set PRNG type in FIPS_mode_set(): leave this to the application.
+     Add default OpenSSL DRBG handling: sets up FIPS PRNG and seeds with
+     the standard OpenSSL PRNG: set additional data to a date time vector.
+     [Steve Henson]
+
+  *) Rename old X9.31 PRNG functions of the form FIPS_rand* to FIPS_x931*.
+     This shouldn't present any incompatibility problems because applications
+     shouldn't be using these directly and any that are will need to rethink
+     anyway as the X9.31 PRNG is now deprecated by FIPS 140-2
+     [Steve Henson]
+
+  *) Extensive self tests and health checking required by SP800-90 DRBG.
+     Remove strength parameter from FIPS_drbg_instantiate and always
+     instantiate at maximum supported strength.
+     [Steve Henson]
+
+  *) Add SRP support.
+     [Tom Wu <tjw@cs.stanford.edu> and Ben Laurie]
+
+  *) Add ECDH code to fips module and fips_ecdhvs for primitives only testing.
+     [Steve Henson]
+
+  *) New algorithm test program fips_dhvs to handle DH primitives only testing.
+     [Steve Henson]
+
+  *) New function DH_compute_key_padded() to compute a DH key and pad with
+     leading zeroes if needed: this complies with SP800-56A et al.
+     [Steve Henson]
+
   *) Initial implementation of SP800-90 DRBGs for Hash and CTR. Not used by
      anything, incomplete, subject to change and largely untested at present.
