Unlike the "Dark Mode" release on 2024-04-01, this one is a normal build which actually functions as a flashlight. The change log is relative to the last normal release, in 2023-12:

General:

• Smooth steps now work in Lockout Mode, if enabled.
• Made eeprom access more reliable, by waiting for power to stabilize before reads and writes.
• Increased voltage resolution to 0.02V. It can, for example, read out 1.20V, 1.22V, 1.24V, 1.26V, 1.28V, or 1.30V.
• Added weak battery detection, to limit power on alkaline, on empty cells, and while powered by a flashing adapter. Should prevent cell overload and magic smoke. Weak battery mode blinks 3X at boot. (d3aa only, so far)
• Made dark "blip"s work better on some types of regulators.
• Fixed bug: 3C in Tactical Mode would change the channel when it shouldn't.
• Fixed bug: Aux channels were off/off/high for levels 0/1/2. Now uses off/low/high.
• Misc improvements to the build process. Can build with Tactical Mode without Momentary Mode. Can build with newer avr-libc. Version strings calculated better now. Github actions can be run manually.
• Documentation updates.

New lights:

• Added &hank-emisar-2ch-fet-joined, for the lighted-switch variant of the D4S. It uses a 2-channel driver with only 1 channel of LEDs. (0137)
