* The new function gpgme_get_protocol_name can be used to convert a
GpgmeProtocol value into a string.
* The GpgmePassphraseCb type now returns a GpgmeError value, and
returns the password string in a new parameter. The gpgme_cancel
function has been removed, just return GPGME_Canceled in the
passphrase callback directly.
* Interface changes relative to the 0.4.0 release:

The function @code{gpgme_cancel} tries to cancel the pending

function @code{gpgme_wait} with this context as its @var{ctx} argument
might notice the cancellation flag and return. It is currently not
