[0.1.0] - 2026-07-24

Initial daemon implementation for controlling Thermalright LCD coolers.
Multi-transport device support: raw bulk, SCSI, HID Type 2/3, and LY bulk protocols across nine USB IDs, with automatic discovery and config-overridable VID:PID selection. 87ad:70db (Peerless Vision / GrandVision 360 AIO) is verified on physical hardware; the remaining IDs are implemented against protocol fixtures — testers wanted.
Responsive layout rendering at negotiated native resolutions (240x240 through ultrawide), with {# canvas: responsive #} opt-in reflow and uniform containment for fixed-canvas layouts.
Support for rendering layout templates using SVG and Tera engine, including built-in layouts.
Integrated sensor providers for system temperature, load, power, and memory metrics, with slow/wedged hwmon chip quarantine.
D-Bus control command-line interface (CLI) to interface with the running daemon.
RAPL udev configuration rule generator to safely allow reading processor power metrics without root.
Optional Tauri-based graphical user interface (GUI) for visual configuration and streaming, including overlay color suggestions derived from the selected background image.
Support for setting background images on the cooler LCD.
Xvfb streaming presets to pipe arbitrary window regions (e.g. conky, cava, btop, nvtop, custom terminal emulators) straight to the cooler.
Whole-daemon profiling harness with committed performance baselines (scripts/profile.sh, docs/profiling-baselines.md).

Release tarball installer now uses the bundled daemon binary when present, while source checkouts still build with Cargo.
RAPL access now uses a dedicated thermalreader group with 0440 permissions instead of world-readable counters.
Xvfb streaming now uses generated Xauthority credentials and private runtime preview frames.

Stream restarts preserve the original layout tick rate when returning from Xvfb mode.
Layout switches now wait for renderer startup confirmation before updating D-Bus state.
SVG text variables are XML-escaped before rendering, so labels containing characters like & do not break previews or daemon rendering.
