* The "protocol auto" default inside fetchmail may be removed from a future
fetchmail release. Explicit configuration of the protocol is recommended.
* Kerberos IV support may be removed from a future fetchmail release.
+* Kerberos 5 support may be removed from a future fetchmail release.
* The --principal option may be removed from a future fetchmail release.
* SIGHUP wakeup support may be removed from a future fetchmail release and
cause fetchmail to terminate - it was broken for many years.
* Linux systems may return duplicates of an IP address in some circumstances if
no or no global IPv6 addresses are configured.
(No workaround. Ubuntu Bug#582585, Novell Bug#606980.)
+* Kerberos 5 may be broken, particularly on Heimdal, and provide bogus error
+ messages. This will not be fixed, because the maintainer has no Kerberos 5
+ server to test against. Use GSSAPI.
