The new version adds a flexible MSG_WINDOW_DUMP message. It supersedes MSG_MFNDUMP. It allows to easily add new types for different ways to refer to (or transfer) the window content (for example to support another hypervisor). For now there's only one window dump type which uses grant references instead of direct mfn references. This allows to move the gui-daemon out of dom0. For now MSG_MFNDUMP is still supported to allow easier upgrading. This should probably be dropped after the next release.
