  OpenSSL CHANGES
  _______________
 
- Changes between 1.0.0e and 1.0.1  [xx XXX xxxx]
+ Changes between 1.0.0f and 1.0.1  [xx XXX xxxx]
+
+  *) Add optional 64-bit optimized implementations of elliptic curves NIST-P224,
+     NIST-P256, NIST-P521, with constant-time single point multiplication on
+     typical inputs. Compiler support for the nonstandard type __uint128_t is
+     required to use this (present in gcc 4.4 and later, for 64-bit builds).
+     Code made available under Apache License version 2.0.
+
+     Specify "enable-ec_nistp_64_gcc_128" on the Configure (or config) command
+     line to include this in your build of OpenSSL, and run "make depend" (or
+     "make update"). This enables the following EC_METHODs:
+
+         EC_GFp_nistp224_method()
+         EC_GFp_nistp256_method()
+         EC_GFp_nistp521_method()
+
+     EC_GROUP_new_by_curve_name() will automatically use these (while
+     EC_GROUP_new_curve_GFp() currently prefers the more flexible
+     implementations).
+     [Emilia Käsper, Adam Langley, Bodo Moeller (Google)]
+
+  *) Use type ossl_ssize_t instad of ssize_t which isn't available on
+     all platforms. Move ssize_t definition from e_os.h to the public
+     header file e_os2.h as it now appears in public header file cms.h

      signature parameters can be passed using this option and in

-  *) Add EC_GFp_nistp224_method(), a 64-bit optimized implementation for
-     elliptic curve NIST-P224 with constant-time single point multiplication on
-     typical inputs.  EC_GROUP_new_by_curve_name() will automatically use this
-     (while EC_GROUP_new_curve_GFp() currently won't and prefers the more
-     flexible implementations).

-     The implementation requires support for the nonstandard type __uint128_t,
-     and so is disabled by default.  To include this in your build of OpenSSL,
-     use -DEC_NISTP224_64_GCC_128 on the Configure (or config) command line,
-     and run "make depend" (or "make update").

      SSL_renegotiate_abbreviated().

+ Changes between 1.0.0e and 1.0.0f [xx XXX xxxx]
+
+  *) Fix handling of BN_BLINDING: now BN_BLINDING_invert_ex (rather than
+     BN_BLINDING_invert_ex) calls BN_BLINDING_update, ensuring that concurrent
+     threads won't reuse the same blinding coefficients.
+
+     This also avoids the need to obtain the CRYPTO_LOCK_RSA_BLINDING
+     lock to call BN_BLINDING_invert_ex, and avoids one use of
+     BN_BLINDING_update for each BN_BLINDING structure (previously,
+     the last update always remained unused).
