VDR Plugin 'streamdev' Revision History
---------------------------------------
- Added streamdev-client support for upcoming streamdev-server versions
with purely priority driven precedence.
- API change of VDR 1.7.26: "avoid device" is no longer available
- Fixed ProvidesChannel() on client always returning true since the new timeout
option has been added.
