Hi, we are going to update the notification rule in dleyna-server. You can follow and answer using github issue tracker here: <https://github.com/01org/dleyna-server/issues/109> To resume: 1 - "LastChange" notification will be remove 2 - Changed notification will be used for "LastChange" notification and "ContainerUpdateID" notification. The rule: If both notifications "LastChange" and "ContainerUpdateID" exist, only "LastChange" will be converted into "Changed" notification. "ContainerUpdateID" will still be converted into "ContainerUpdateID" notification. If only "ContainerUpdateID" notification exists, it will be converted into a "Changed" notification AND "ContainerUpdateID" notification. When "ContainerUpdateID" is converted, ChangeType = MOD (see github for details) The purpose of this new signal is to have only 'one entry' for all the notification of change that came from the server and to avoid duplicated signals. Ex: if a server support "LastChange" notification and "ContainerUpdateID" notification and your application register for both, you will receive 2 notifications on a folder change. By using "Changed", your application will have a single way of managing change without checking the server capabilities. If you have any comments, you can answer here or on github.
