  Changes between 0.9.6 and 0.9.7  [xx XXX 2000]
 
+  *) Fix a memory leak in err.c: free err_data string if necessary.
+     [Bodo Moeller]
+
+  *) Function EC_POINTs_mul for simultaneous scalar multiplication
+     of an arbitrary number of elliptic curve points, optionally
+     including the generator defined for the EC_GROUP.
+     EC_POINT_mul is a simple wrapper function for the typical case
+     that the point list has just one item (besides the optional
+     generator).
+     [Bodo Moeller]
+
+  *) First EC_METHODs for curves over GF(p):
+
+     EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
+     operations and provides various method functions that can also
+     operate with faster implementations of modular arithmetic.     
+
+     EC_GFp_mont_method() reuses most functions that are part of
+     EC_GFp_simple_method, but uses Montgomery arithmetic.
+
+     [Bodo Moeller; point addition and point doubling
+     implementation directly derived from source code provided by
+     Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
+
+  *) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
+     crypto/ec/ec_lib.c):
+
+     Curves are EC_GROUP objects (with an optional group generator)
+     based on EC_METHODs that are built into the library.
+
+     Points are EC_POINT objects based on EC_GROUP objects.
+
+     Most of the framework would be able to handle curves over arbitrary
+     finite fields, but as there are no obvious types for fields other
+     than GF(p), some functions are limited to that for now.
+     [Bodo Moeller]
+
+  *) Add the -HTTP option to s_server.  It is similar to -WWW, but requires
+     that the file contains a complete HTTP response.
+     [Richard Levitte]
+
+  *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
+     change the def and num file printf format specifier from "%-40sXXX"
+     to "%-39s XXX". The latter will always guarantee a space after the
+     field while the former will cause them to run together if the field
+     is 40 of more characters long.
+     [Steve Henson]
+
+  *) Constify the cipher and digest 'method' functions and structures
+     and modify related functions to take constant EVP_MD and EVP_CIPHER
+     pointers.
+     [Steve Henson]
+
   *) Implement ssl23_peek (analogous to ssl23_read), which previously
      did not exist.
