Software Version 4.00 - a new, not listed functions

As far as I can see, the update 4.0 is equivalent to the 7.60 firmware version of the Fenix 5X watch. In this respect, I would like to add that Garmin did not include a few new features in its description of the improvements to version 4.0:

1. Added support for configuring the track color of saved activities. (Settings > Map > Track Color)
2. Added support for configuring 'Off Course' alerts. (Settings > Navigation > Alerts > Off Course.)
3. Added support for setting up Alarm Clock as a Controls and a Hot Key item. Go to Settings > System > Hot Keys or Settings > Controls > Add New to enable this.
4. Added a setting to control whether segment start pins are viewable on the Map page. Go to Settings > Activities and Apps > Run/Bike > Run/Bike Settings > Map. Turn off 'Use Sys. Settings.' You can now toggle 'Draw Segments.'
5. Added the ability to access 'Broadcast Heart Rate' from the Controls menu (Settings > Controls) as well as through the system Hot keys (Settings > System > Hot Keys).

Therefore, it is LIKELY that other enhancements have also been made, which unfortunately are not as visible as those listed above, but are detailed in the change descriptions from version 6.0 to version 7.60 on the Fenix 5X watch update page. The list is below:
  • Improved device key handling while using Connect IQ apps.
