+Version 4.1-dev-809-g8a69f5ea
+====
+**Enhancements**
+* Add another item of metadata with the code `phb0` and the DBus property name `FirstFramePosition`. This is similar to the `phbt` and `FramePosition` metadata, except that it is updated for the first frame of a play session. It can be ignored, as a `phbt` token is also sent when the first frame is output.
