Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
+ *) Implement binary inversion algorithm for BN_mod_inverse in addition
+ to the algorithm using long divison. The binary algorithm can be
+ used only if the modulus is odd. On 32-bit systems, it is faster
+ only for relatively small moduli (roughly 20-30% for 128-bit moduli,
+ roughly 5-15% for 256-bit moduli), so we use it only for moduli
+ up to 450 bits. In 64-bit environments, the binary algorithm
+ appears to be advantageous for much longer moduli; here we use it
+ for moduli up to 2048 bits.

+
+ *) Change bctest again: '-x' expressions are not available in all
+ versions of 'test'.
+ [Bodo Moeller]
+
+ *) Fix a couple of memory leaks in PKCS7_dataDecode()
+ [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
+
+ *) Change Configure and Makefiles to provide EXE_EXT, which will contain
+ the default extension for executables, if any. Also, make the perl
+ scripts that use symlink() to test if it really exists and use "cp"
+ if it doesn't. All this made OpenSSL compilable and installable in
+ CygWin.
+ [Richard Levitte]
+
*) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
could not support the combine flag in choice fields.
[Steve Henson]
*) Change bctest to avoid here-documents inside command substitution
(workaround for FreeBSD /bin/sh bug).
+ For compatibility with Ultrix, avoid shell functions (introduced
+ in the bctest version that searches along $PATH).
[Bodo Moeller]
*) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
