Changes between 0.9.7 and 0.9.8 [xx XXX 2002]
*) Implement fast modular reduction for pseudo-Mersenne primes
used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c).
EC_GROUP_new_curve_GFp() will now automatically use this
if applicable.
[Nils Larsch <nla@trustcenter.de>]
*) Change the ENGINE framework to automatically load engines
dynamically from specific directories unless they could be
found to already be built in or loaded. Move all the
