Highlights & Key Features
-
Infinite Color Engine: Breaks the standard RGB 24-bit barrier using high-precision floating-point arithmetic. By shifting transformations to linear sRGB space, we provide physically accurate light reproduction and native deep-color support for devices like Philips Hue and LIFX. This advanced processing also guarantees remarkably smooth color transitions and gradients, effectively eliminating color banding and maximizing accuracy for a natural ambient experience.

Advanced Smoothing: Introduces a new generation of smoothing algorithms, including the innovative Hybrid Inertia mode. Designed for a more natural and fluid response, these algorithms make ambient lighting transitions exceptionally smooth and visually pleasing.
-
Adaptive Dithering & RGBW Enhancements: Powered by the fully realized Infinite Color Engine, we've implemented adaptive temporal dithering specifically for RGBW drivers (such as SK6812). This delivers silky-smooth animations and color transitions while avoiding flickering during static scenes. Alongside dithering, this update also introduces finer control over the dedicated white channel.

Introducing Hyperk: Our new wireless solution is a brand-new, dedicated project that fills the final gap in our LED driver lineup. It's a robust wireless controller compatible with a massive range of platforms, including ESP8266, ESP32 (S2, S3, C2, C3, C5, C6), Raspberry Pi Pico W (RP2040, RP2350). A minimalist solution with a basic WLED-compatible API, ensuring seamless integration with environments like HyperHDR or Home Assistant. The latest update brings HyperSerial, multi-segment and power relay control support.

Massive Performance Leap: Video decoding for YUV, NV12, and P010 codecs has been heavily optimized, delivering impressive speed improvements of up to 46%. Additionally, Linux users benefit from an enhanced Pipewire implementation featuring hardware GPU scaling to drastically minimize CPU overhead.
-
Hardware & Ecosystem Expansion: Brings highly anticipated native PWM support for the Raspberry Pi 5, expanding options for modern builds. We have also transitioned our entire infrastructure to the modern Qt 6.8+ framework, resulting in noticeably smaller installers and seamless version consistency across all supported platforms. The build system now supports generating distribution-specific packages that rely on system dependencies instead of bundling external libraries. Additionally, configuration storage conforms to platform-native standards across all operating systems, with full Filesystem Hierarchy Standard compliance on Linux.
-
Signed Windows Installers: Thanks to the generous support of the SignPath Foundation, our Windows installers are now officially digitally signed. This guarantees that our binaries are safe and untampered with.
-
Modern C++20 Foundation: Marks a strategic transition to the C++20 standard. By leveraging the latest language capabilities, this update significantly boosts core engine performance, enhances overall system robustness, and ensures highly efficient long-term maintainability.
