Changes made from version 7.10 to 7.54:
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).
Improved the smart notification text layout for longer messages.
Improved manual weight entry for Rep Counting. When entering the weight for a set, the default value will be the weight entered for the previous set instead of 0.
Improved the VO2 Max gauge in the Performance widget so that the arrow indicator is more accurate.
Improved syncing of user settings and statistics between the device and Garmin Connect. Addresses issues like alarms being changed unexpectedly.
Fixed an issue causing the Lactate Threshold page in the Performance widget to not show if an auto-detected BPM value is the same as one that was manually entered.
Fixed an issue where the entered angle field would change its contents to a bad value within Jumpmaster.
Fixed an issue where the scrollbar would disappear momentarily when adding a chart page (for example altimeter) to the activity data field page loop.
Fixed an issue where the data field 'Gear Battery' showed no value on the Varia Vision.
Fixed an issue where laps were not being recorded correctly while performing a lactate threshold test.
