Merged a few pull requests, minor improvements, nothing big. Users can now configure if and when the button LEDs light up during use and during POVD.

General:

• Added config options to make button LED brightness thresholds configurable.
  Battcheck -> 7H -> Options 3+4 now set the aux low/high ramp levels, for the brightness of the button while the main LEDs are on, and the brightness of Post-Off Voltage Display (POVD) after turning the main LEDs off.
  (may be options 2+3 on lights with no RGB aux, instead of 3+4)
  (new options are only available on lights with more than 8 KiB ROM)
• Lockout mode now only does momentary moon/low on 1st and 2nd presses.
• Documentation updates.
• Fixed broken GitHub CI.

Hardware-specific changes:

• &emisar-d3aa: Reduced moon preflash even more.
  If it still flashes, it probably can't be fixed in software.

Pretty minor release. Things have been weird lately.

General:

• Removed access to strobe/mood modes in Extended Simple UI, to make it more safe and simple by default.

New lights:

• Added &hank-lume-x1 (0281): Covers all of Hank's recent Lume X1-based lights.
• Added &wurkkos-ts10-rgbaux-lowfet (0712): Variant with lower max power, created at Wurkkos's request, to stop new batches of low-Vf lights from damaging themselves.

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)
• Added &hank-emisar-d3aa, the first "3rd generation" torch (avr32dd20, thefreeman HDR driver). (0161)
• Added &fireflies-pl47g2-219, a reduced-power version of the PL47G2.

Hardware-specific changes:

• &lumintop-fw3x-lume1: Reduced visible pulsing on low modes.

🔦 What is it?

I don't want to over-hype anything, but this may perhaps be the single most popular feature ever. According to extensive market research and numerous studies, it is preferred by anywhere from 80% to 95% of all users globally, and has become an industry standard on nearly all platforms. Again and again, one feature shines above all others as the most highly requested:

Say hello to Dark Mode, the sleek and sophisticated new Anduril interface that transforms your flashlight experience into an immersive journey through the shadows.

🌙 Why Dark Mode?

Imagine navigating through the night with the elegance and ease of darkness at your fingertips. Dark Mode isn't just a trend; it's a lifestyle. Here's why you'll love it:

• Enhanced Comfort: Say goodbye to harsh glare! Dark Mode offers a softer, more comfortable lighting experience, perfect for late-night walks, camping trips, or simply getting to the bathroom in the middle of the night.

• Modern Aesthetics: Embrace a fresh, modern look that's easy on the eyes and effortlessly stylish. Black is the new black, because it never goes out of style.

• No More Blue Light Interference: The modern world is full of light pollution and other ocular hazards which disrupt the circadian rhythm and can even cause severe health problems like chronic fatigue and macular degeneration. LEDs are particularly egregious thanks to their high intensity blue wavelengths. But with Dark Mode, you can leave all those troubles in the past and get a good night's sleep, every night.

• Environmental Consciousness: Embrace sustainability with Dark Mode's energy-efficient design. By conserving power, you contribute to a brighter, greener future for generations to come.

Update: The release a few hours ago jumped the gun a bit, so to speak, with a broken Jump Start feature (bug #55). This new release fixes that.

2023-12-03

This release is somewhat higher risk than usual, because so many large things
changed deep in the code. I did major restructuring and refactoring across the
entire project. It should work fine, but be on the lookout for any weird
problems.

General:

• Moved from Bzr + Launchpad to Git + GitHub, by popular request.
• Completely reorganized the project files. Really, a massive amount of
  restructuring. The flashlight end-user interface is still the same, but
  expect to have to learn the code layout from scratch. Read the [README.md]
  for info about getting started with the new project layout.
• Added support for AVR DD MCUs like avr32dd20. This is the recommended
  MCU to use in new flashlights.
• Added ability to use turbo in momentary mode.
• Upgraded battery voltage resolution from 0.1V steps to 0.025V steps.
  Battery check has an extra digit which can be 0, 2, 5, or 7 (for example, for
  3.70V, 3.725V, .3.75V, and 3.775V).
• Made Battery Check more consistent, so it's less likely to give different
  values on the 1st and 2nd readout.
• Re-calibrated timing on each MCU type, so a 1-second beacon flasher should be
  closer to 1 actual second now... mostly. Timing still varies significantly
  from one light to another.
• Fixed default bike flasher brightness on some builds. It was sometimes way
  too high.
• Fixed RGB aux turning on during momentary mode sometimes.
• Converted documentation to markdown format, and rewrote a lot of it.
• Fixed some build issues with specific compile-time options.
• Changed the format of version numbers. It now uses the most recent
  release tag instead of the build date, and may have additional numbers at
  the end to indicate distance from the last official release, and whether
  the repo was clean or dirty. Today's release is MODEL-2023-12-03. A
  derivative built 52 commits later in a dirty repo would look like
  MODEL-2023-12-03-52-1.

New lights:

• Added &thefreeman-avr32dd20-devkit. It's only used for development purposes,
  but otherwise it's pretty neat. It'll be the basis for many new lights in
  the future. (model 1632dd20)

Hardware-specific changes:

• Improved idle efficiency on attiny1616, which was spending entirely too much
  time doing math it didn't actually need.
• &hank-*-boost: Fixed flicker while holding button at moon level. Reduced
  ripple on low modes. (0216, 0253, 0273)
• &lumintop-blf-gt: Added smooth steps. Removed a couple other things to make
  room. (0321)
• &lumintop-fw3x: Multiple fixes and upgrades... (0314, 0315)
  • Fixed thermal regulation. Also fixed the external temperature sensor.
  • Made moon much lower, and made ramp much smoother, by upgrading to DSM.
  • Fixed the aux RGB pinouts because Lumintop got the wiring backward.
  • Added a second build target for people who fixed the wires manually.
  • Added red/blue police color strobe.
  • Made low modes more efficient with underclocking. Moon should run at least
    4X as long as it did before.
  • Fixed party strobe being blurry.
  • Added documentation for the FW3X's multiple, uh, quirks.
• &sofirn-lt1s-pro: Disabled manual memory, memory timer, and extended simple
  UI by default. Simple mode is simpler, and the factory settings should be
  more consistent with other lights now. (0623)

General:

• Finally finished converting all lights to the multi-channel API.
  (but a few are untested due to hardware being unavailable)
• Enabled smooth steps on almost all supported lights, including old ones.
  (in some cases, on old t85 lights, some other things may have been removed
  to make room)
• Made smooth steps work better, and fixed several bugs.
• Added/fixed RGB aux voltage on dual-fuel AA/li-ion drivers.
• Fixed delay timing on all supported MCUs, so 1 "second" is closer to an
  actual second (like in beacon mode or biking mode).
  (especially attiny1616, which was 17% too slow)
• Raised default thermal limit to 50C on attiny1616-based lights, since
  it doesn't need as big an error margin as older MCUs.
• Fixed missing item in globals menu on some lights.
• Misc internal improvements and per-light tweaks.
• Added a ChangeLog.md, to periodically summarize changes in a format which is
  more readable than the raw commit logs.

New lights:

• thefreeman-boost21-6a: Added. (1631)
  (very nice HDR boost driver which fits into a FW3A)
• thefreeman-boost-fwaa: Added. (1632)
  (very nice AA/li-ion HDR boost driver which fits into a FWAA)

Hardware-specific changes:

• Upgraded several builds to use delta-sigma modulation (DSM), for
  lower lows and smoother ramping with less flicker or ripple:

  • blf-lt1 (0621)
  • blf-lt1-t1616 (0622)
  • emisar-d4k-3ch (0151)
    (dramatically improves resolution and low modes on its 8-bit channel)
  • noctigon-dm11-boost (0273)
  • noctigon-kr4-boost (0216)
  • noctigon-k1-boost (0253)
  • noctigon-m44 (0143)

• Upgraded some builds to use dynamic PWM, for lower lows and smoother ramping:

  • blf-q8-t1616, sofirn-sp36-t1616 (0613, 0614)
  • gchart-fet1-t1616 (1618)
  • noctigon-k1-sbt90 (0252)

• wurkkos-ts10, wurkkos-ts10-rgbaux: Fixed too-high default ceiling. (0713, 0714)

2023-06-29

2023-06-29

• Fixed red aux blink on 1st frame of post-off voltage display
• Removed Harry Potter references because its author (J.K. Rowling) spreads
  hate
• noctigon-kr4: Fixed thermal regulation (0211, 0212, 0213, 0214, 0215, 0216)

2023-10-01

General:

• Updated a bunch of lights to work with the new multi-channel API.
• Added "smooth steps" a.k.a. "soft start", to make on/off and step changes
  smooth. (enabled by default, can be turned off in Ramp Extras menu)
• User can save a different channel mode for each strobe-group mode.
• Made strobes/blinkies more responsive in Tactical Mode.
• Fixed bug: Tactical Mode clobbers strobe group memory.
• Fixed some minor post-off voltage display bugs.
• Made RGB button brightness update faster in blinky modes.
• Fixed bug: Wrong channel after colored factory reset.
• attiny1616, attiny1634: Partially fixed oscillating aux LED voltage
  colors while off. Better than before, but can still happen in some cases.
• attiny1616: Fixed spurious voltage warnings in sleep mode. (it could
  sometimes go from Lockout mode to Off mode by itself)
• Lots of internal refactoring.

New lights:

• emisar-2ch-fet: Added. (0136)
• emisar-d4k-3ch: Added. (0151)
• noctigon-m44: Added. (0143)
• wurkkos-ts10-rgbaux: Added. (0713)

Hardware-specific changes:

• ff-e01, ff-pl47, ff-pl47g2: Enabled smooth steps instead of SOS mode.
  (0421, 0422, 0423, 0441)
• emisar-2ch, noctigon-m44: Added RGB aux channel modes. (0135, 0143)
• emisar-2ch-fet, noctigon-k9.3: New ramps with better-calibrated shape.
  (0136, 0261)
• emisar-d4v2-nofet: New ramp table. (0115)
• emisar-d4sv2-tintramp: Removed / renamed. (0135, 0136)
• noctigon-k9.3: Fixed years-old mess. Merged builds, converted to
  multi-channel, removed old builds, generally got K9.3 working quite a bit
  better. (0261, 0262, 0263, 0265, 0266, 0267)
• noctigon-m44: Lower moon, and greatly reduced flicker. (0143)
• sofirn-lt1s-pro: Allow configuring the blink channel. (0623)
• wurkkos: Raised default temperature limit to 50 C. (07xx)
• wurkkos-ts10: Better / smoother ramp. (0713, 0714)
