Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
+ *) Make SMIME_write_PKCS7() write mail header values with a format that
+ is more generally accepted (no spaces before the semicolon), since
+ some programs can't parse those values properly otherwise. Also make
+ sure BIO's that break lines after each write do not create invalid
+ headers.
+ [Richard Levitte]
+
*) Make sk_sort() tolerate a NULL argument.
