  1. v0.2.0

    2026-08-08

    Latest5 changes
    • addedEcosystem widening — Cryo now targets the whole alienware-wmi family, not one machine. The daemon probes hardware capabilities at startup (available profiles, G-Mode, fan-boost writability, lighting controller, turbo control, NVML) and the GUI, tray, and CLI render only what exists.
    • addedcryoctl doctor — a hardware/driver compatibility report (model, driver, fans, profile choices, power supply, turbo, AW-ELC, NVML, daemon capabilities) that works without root or a running daemon, formatted for pasting into GitHub model reports.
    • changedProfile names are now translated from what the kernel actually advertises: on G-Mode machines balanced-performance is Performance and performance is G-Mode; on machines without G-Mode, performance is labeled Performance — the old static mapping would have mislabeled it. Auto-rules resolve through the same map with sensible fallbacks.
    • changedPower-supply and CPU-turbo controls are discovered instead of hardcoded — battery auto-rules now work on machines that name their AC adapter ACAD/AC0/ADP1, and AMD machines get cpufreq/boost turbo control.
    • addedCompatibility matrix (docs/COMPATIBILITY.md) plus model-report and bug-report issue templates built around doctor output.

  2. v0.1.0

    2026-08-06

    8 changes
    • addedInitial release — the frozen core. cryod, a root daemon under systemd, owns all hardware access through the in-kernel alienware-wmi driver over sysfs: no acpi_call, no out-of-tree modules.
    • addedSix power modes — Cool, Quiet, Balanced, Performance, G-Mode, and Custom — translated to kernel platform profiles (performance→balanced-performance, gmode→performance, custom→custom).
    • addedCustom fan curves with linear interpolation, a 3 °C hysteresis dead zone, and minimum 5-point write suppression — plus Thermal Guard, an emergency failsafe in every profile that forces 100% fan boost at CPU ≥ 88 °C or GPU ≥ 85 °C and releases once both temps drop 10 °C below trip.
    • addedGame detection as a real state machine over NVML — a dGPU graphics process off the ignore list with ≥ 400 MB VRAM and sustained load (≥ 50% for 10 s in, ≤ 20% for 45 s out) auto-enters G-Mode and restores the prior profile on quit. Degrades gracefully without NVML.
    • addedAuto profiles on transitions only: on_battery→quiet, on_ac→balanced, on_game→gmode, after_game→previous — manual picks always stick until the next event.
    • addedAlienFX lighting via a raw HID SET_REPORT reimplementation (VID 0x187C, PIDs 0x0550/0x0551, 33-byte packets) for the 4-zone keyboard — eight effects including the signature Quantum cyan↔violet morph, plus brightness, persisted and restored on boot.
    • addedLive telemetry at 1 Hz — CPU/GPU temps, four fan RPMs and boosts, dGPU utilization, 120-sample sparklines, session peaks, and a tray tooltip — pushed to every subscribed client over /run/cryo.sock (JSON lines, group-owned, mode 0660).
    • addedPySide6/Qt 6 + QML GUI, the cryoctl CLI (status, watch, profile, gmode, boost, turbo, light, brightness, config), a system tray icon, and a CPU Turbo toggle via intel_pstate/no_turbo.
