+defined by RFC 4880 as well as some extensions (e.g., RFC 6637, which
+describes ECC cryptography) for OpenPGP.  This includes support for unbuffered
+message processing.
+
+A few features that the OpenPGP community considers to be deprecated (e.g.,
+version 3 compatibility) have been left out.  We have also updated some
+OpenPGP defaults to avoid foot guns (e.g., we selected modern algorithm
+defaults).  If some functionality is missing, please file a bug report.")
