Welcome to the beta2 test release of HyperHDR v22! The introduction of the Infinite Color Engine has reached its next milestone - with adaptive dithering for RGBW drivers as the "cherry on top" for even smoother animations. Windows installers are now officially signed thanks to the SignPath Foundation. We are also introducing Hyperk, a new dedicated wireless LED controller that fills the final gap in our previously wired-only driver collection.
Highlights & Key Features
-
Adaptive Dithering for RGBW: Powered by the fully realized Infinite Color Engine, we've implemented adaptive temporal dithering specifically for RGBW drivers. What does this mean for you? Silky-smooth animations and color transitions. Thanks to its precise application, it maintains stability and avoids flickering during static scenes.

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. Please note: it takes a little time for a new certificate to build reputation. Once established, Windows SmartScreen will stop flagging our installers as coming from an unverified source.

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 multi-segment support and power relay control. We've also included initial support for popular custom boards from GLEDOPTO, DOMRAEM, and Athom/IoTorero.

A quick note on wireless controllers: Because Hyperk (along with Philips Hue and HyperSPI/HyperSerial controllers) is now my personal daily driver, it will serve as the primary and officially supported wireless controller for HyperHDR moving forward. You are, of course, welcome to keep using WLED or any other wireless driver! The WLED integration is mature and has long been stable, but to focus development on our in-house drivers, I’m moving it toward a community-driven support model. While I will have limited capacity for hands-on troubleshooting of WLED configurations, I welcome the community to take a more active role in maintaining this area and assisting fellow users.

- Update language files. Thanks @AstaRom (#1445)
- More accurate simplified Chinese translation. Thanks @DaBinQwQ (#1520)
- Fix: use IANA-compliant HTTP reason phrases. Thanks @joeshull (#1510)
- Fix: Initial smoothing surge after period of static video input (#1410)
- Fix: Minimum brightness preservation in YUV and Hybrid-Inertia smoothing modes (#1410)
- Upgrades old style format logging (with %) to c++20 format in some places (#1410)
- Restores custom user RGB order at the start (#1410)
- Restores compatibility with Qt5.15 (#1410)
- Improved state management of the software grabber during sleep and monitor‑suspend events (#1410)
- PipeWire is particularly sensitive to sessions resuming too early after such events and, despite having provided a saved session token, would display a new source select dialog after resume when screen‑lock‑after‑suspend was enabled
- Set disableOnLocked option enabled by default, because software grabbers for ex. Pipewire wont function properly without it (#1410)
- Fix translation resources
- Infinite Color Engine: new anti-flickering filter in the smoothing configuration (#1410)
- Implements an anti-flickering filter that minimizes quantization jitter on 8-bit-per-channel drivers (24-bit RGB). Deep color capable drivers (like Philips Hue using entertainment mode) are bypassed as they don't suffer from LSB oscillation.
- Improved handshake stability connecting to Philips Hue bridge using OpenSSL 3.2+ (#1410)
- Fix: Add missing Qt meta-type registrations (#1456)
