Changes between 0.9.5a and 0.9.6 [xx XXX 2000]
+ *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
+ This makes DSA verification about 2 % faster.
+ [Bodo Moeller]
+
+ *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
+ (meaning that now 2^5 values will be precomputed, which is only 4 KB
+ plus overhead for 1024 bit moduli).
+ This makes exponentiations about 0.5 % faster for 1024 bit
+ exponents (as measured by "openssl speed rsa2048").

*) Rename memory handling macros to avoid conflicts with other
software:
