Changes between 0.9.8b and 0.9.8c [xx XXX xxxx]
+ *) Fix RSA blinding Heisenbug (problems sometimes occured on
+ dual-core machines) and other potential thread-safety issues.
+ [Bodo Moeller]
+
*) Add the symmetric cipher Camellia (128-bit, 192-bit, 256-bit key
versions), which is now available for royalty-free use
(see http://info.isl.ntt.co.jp/crypt/eng/info/chiteki.html).
Changes between 0.9.7h and 0.9.8 [05 Jul 2005]
+ [NB: OpenSSL 0.9.7i and later 0.9.7 patch levels were released after
+ OpenSSL 0.9.8.]
+
*) Add libcrypto.pc and libssl.pc for those who feel they need them.
[Richard Levitte]
differing sizes.
[Richard Levitte]
+ Changes between 0.9.7j and 0.9.7k [xx XXX xxxx]
+
+ *) Fix RSA blinding Heisenbug (problems sometimes occured on
+ dual-core machines) and other potential thread-safety issues.
+ [Bodo Moeller]
+
+ Changes between 0.9.7i and 0.9.7j [04 May 2006]
+
+ *) Adapt fipsld and the build system to link against the validated FIPS
+ module in FIPS mode.
+ [Steve Henson]
+
+ *) Fixes for VC++ 2005 build under Windows.
+ [Steve Henson]
+
+ *) Add new Windows build target VC-32-GMAKE for VC++. This uses GNU make
+ from a Windows bash shell such as MSYS. It is autodetected from the
+ "config" script when run from a VC++ environment. Modify standard VC++
+ build to use fipscanister.o from the GNU make build.
+ [Steve Henson]
+
Changes between 0.9.7h and 0.9.7i [14 Oct 2005]
*) Wrapped the definition of EVP_MAX_MD_SIZE in a #ifdef OPENSSL_FIPS.
