Just saw that the new BETA 6.02 was released for the Venu.
BETA - Venu SW 6.02 is available - Venu - Health & Wellness - Garmin Forums
Unfortunetly, it's missing some of the advanced features which has been added to the Forerunner Line and added to other Garmin watches.
Was hopen so much that the new advanced sleep tracking will be added to the Venu.
