I've tried to determine some Anduril firmware versions (or a guess) of a few Anduril flashlights that I've checked out:
Meote FM1 copper = has version check: 2019-09-28
FT03-Mini = has version-check: 2019-09-28
Sofirn SP36 BLF Anduril, Sofirn IF25A, Astrolux EC01, Astrolux EC03
= I think it has been determined by TK that they run the same old version of Anduril:
all of them do not have the 2-level brightness in lockout mode, nor manual memory mode. So firmware has to be earlier than 2019-05-22 (this firmware date added the 2-level lockout). The button blinking is a "breathing" pattern, which is added in Anduirl firmware date 2018-12-14. So the firmware used by these flashlights would be somewhere between 2018-12-14 and 2019-05-22.
Astrolux HL01 = has 'factory reset' function, but no 'version-check' function [between 2019-06-27 & 2019-09-24]
Astrolux FT03S = has 'factory reset' function, but no 'version-check' function [between 2019-06-27 & 2019-09-24]
('factory reset' added in firmware version 2019-06-27, 'version-check' added in 2019-09-24)
which would mean these 2 flashlights have Anduril firmware version dated between 2019-06-27 and 2019-09-24
Haikelite HK04
- Anduril version 2019-06-02 (has manual memory via 5H); but no factory-reset function
(firmware 2019-06-02 added 'manual memory' function; 'factory reset' added in 2019-06-27)

I tried to check some functions of Anduril (in the Anduril repository change log) to help determine which functions added in which date (for Anduril versions that didn't have the 'version-check' function yet)
2018-12-14: fancy aux-LED (button switch LED) blinking mode (like heartbeat breathing effect) on BLF Q8/SP36
2019-05-22: 2-level lockout brightness (4-clicks); momentary strobe mode possible (go to strobe modes before going to momentary mode)
2019-06-02: manual memory option (5H) ; button-release time-out is a bit faster
2019-06-27: factory reset function (hold button while tightening the tailcap)
2019-09-24: version-check function (15C) ; safety ramp-down if button held too long
Since I don't see any "Anduril 2" category on the initial post of this thread (list of lights classified by UI), I'm wondering: are there any lights currently sold with Anduril 2 already installed?
