+Features
+ * Added partial support for parsing the PKCS #7 cryptographic message
+ syntax, as defined in RFC 2315. Currently, support is limited to the
+ following:
+ - Only the signed data content type, version 1 is supported.
+ - Only DER encoding is supported.
+ - Only a single digest algorithm per message is supported.
+ - Only 0 or 1 certificates are supported per message, which must be in
+ X.509 format.
+ - There is no support for certificate-revocation lists.
+ - The authenticated and unauthenticated attribute fields of SignerInfo
+ must be empty.
+ Many thanks to Daniel Axtens, Nayna Jain, and Nick Child from IBM for
+ contributing this feature. Thanks to Demi-Marie Obenour for contributing
+ various improvements, tests and bug-fixes.
