Changes between 0.9.7a and 0.9.8 [xx XXX xxxx]
+ *) Support for single pass processing for S/MIME signing. This now
+ means that S/MIME signing can be done from a pipe, in addition
+ cleartext signing (multipart/signed type) is effectively streaming
+ and the signed data does not need to be all held in memory.
+
+ This is done with a new flag PKCS7_PARTSIGN. When this flag is set
+ PKCS7_sign() only initializes the PKCS7 structure and the actual signing
+ is done after the data is output (and digests calculated) in
+ SMIME_write_PKCS7().
+ [Steve Henson]
+
*) Add full support for -rpath/-R, both in shared libraries and
applications, at least on the platforms where it's known how
to do it.
