From ${URL} : When starting the x11vnc with -localhost specified, it fail to restrict IPv6 accessibility to localhost. This is in conflict with the manual, which states: -localhost [...] IPv6: if IPv6 is supported, this option automatically implies the IPv6 loopback address '::1' as well. @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
Is this a standardised message input ? Where does it say this requires a version bump ?
