hardware 2.4.2) with the 'subsurface-4.9.6-121-gf42dee8ac2e4.exe' binary
under downloads/tests on Windows 10 with an empty dive log and Bluetooth
mode 'Auto'.  It successfully downloaded 203 of the 206 dives on the
computer, but produced a 'Dive data import error' and failed to download
the earliest few dives.  I closed without saving and started Subsurface -v
from the command prompt with the hope of working out what the error was but
this time all the dives were downloaded.  Command prompt output is copied
below.
Found device:  "Petrel" "00:13:43:0E:6B:D0"
Starting download from  BT
downloading only new dives
INFO: dc_device_open error value of 0
new firmware version 44 for DC model Shearwater Petrel 2 deviceId 0x1c94852d
new firmware version 29 for DC model Shearwater Petrel 2 deviceId 0x1c94852d
new firmware version 28 for DC model Shearwater Petrel 2 deviceId 0x1c94852d
Finishing download thread: 206 dives downloaded

I note that the dive computer is identified as a Petrel rather than Petrel
2.

My only real concern is that I've been reminded I've had only one dive
since March last year :(
