### Changes between 1.1.1 and 3.0 [xx XXX xxxx]
+ * Add PKCS7_get_octet_string() and PKCS7_type_is_other() to the public
+ interface. Their functionality remains unchanged.
+
+ *Jordan Montgomery*
+
* Deprecated EVP_PKEY_set_alias_type(). This function was previously
needed as a workaround to recognise SM2 keys. With OpenSSL 3.0, this key
type is internally recognised so the workaround is no longer needed.

+PKCS7_get_octet_string() returns a pointer to an ASN1 octet string from a

+As the B<0> implies, PKCS7_get_octet_string() returns internal pointers which
