Garmin-Blake, is there a page where I can find a separate change log for ANT/BLE/BT versions, GPS updates, Sensor Hub updates, etc?

I am still on 2.80 as that is stable for me and I just lost way too much time on fixing my watch before. Since that the only version I was considering is 3.30. However I am thinking about to stay on SW 2.80 while updating the rest, like ANT/BLE/BT from 3.60 to 5.01, Sensor HUB from 2.50 to 3.20, GPS from 2.50 to 2.70 therefore I am looking for the change logs. Do you think it makes sense to do these updates w/o updating the main SW? Or shall I just wait for another stable main SW release in the future. (I call stable when it has no major flaws and main functionality of the watch is working perfectly.)
