@bagder Yup, I see the Garmin Fenix 5 (2017), Forerunner 245 (2019) and Venu Sq (2021). The one in the photo is a Venu 3s (2023) and features exactly the same wording.

Not too surprising, the base firmware doesn't seem to change hugely (mostly new display tech and upgraded sensor hardware), and most of the user visible stuff runs in a custom VM. If I had to guess, I would say maybe libcurl is used for the sync-over-wifi feature for bulk downloads like maps and firmware updates.
