Changes between 0.9.7a and 0.9.7b [xx XXX 2003]
Changes between 0.9.7b and 0.9.7c [xx XXX 2003]
*) Various S/MIME bugfixes and compatibility changes:
output correct application/pkcs7 MIME type if
PKCS7_NOOLDMIMETYPE is set. Tolerate some broken signatures.
Output CR+LF for EOL if PKCS7_CRLFEOL is set (this makes opening
of files as .eml work). Correctly handle very long lines in MIME
parser.

Changes between 0.9.7a and 0.9.7b [10 Apr 2003]
*) Countermeasure against the Klima-Pokorny-Rosa extension of
