Hi,

Here we have fenix 5S Plus, ANT/BLE/BT software version 6.15
and the changes history says :
"Change History
Changes made from version 6.06 to 6.11:
Fix an iOS reconnection issue on some phones.
Changes made from version 5.04 to 6.06:
Fixed Powerbeats Pro headphone volume issue.
Changes made from version 4.30 to 5.04:

but nothing about changes made from version 6.11 to 6.15
Does anybody knows what are the changes between version 6.11 and 6.15 ?
