The HyperHDR v20 release was created with the participation of many users (thanks to everyone, especially to @AstaRom) and brings many important new features and fixes. More than several dozen thousand lines of code were changed, including almost the entire application base was rewritten using newer technologies, which then required several months of testing to make sure that it would not negatively affect stability. Thanks to the rebuilt LED rendering model, even more precise refreshing is achieved and the use of Smart Pointers gives us greater control over memory management. Software grabbers have been significantly improved, including hardware acceleration for Pipewire (Linux) and in particular a huge leap in performance and capabilities has occurred in the case of the DirectX grabber for Windows (native system HDR support without LUT and Pixel & Vertex Shader acceleration). At that time, a new HyperSerialPico project was also created, thanks to rp2040 PIO IO co-processor we received a driver offering even more precise timings for LED rendering than ESP32/Esp8266 and it allows the use of ready-made boards with a built-in level shifter: which significantly simplifies the construction of new HyperHDR setups regardless of the platform on which you host it.
Below is the full list of changes. Have fun!
New features:

LED devices:
- Smoothing clock is integrated directly within led driver: no more two separated & unsynchronized clocks for smoothing and led driver, also much more precise refresh times. Discussed here → #691
- Add support for Raspberry Pi Pico (Rp2040) HyperSerialPico #560
- HyperHDR driver for WLED has been switched to WLED Audio-Reactive-Led-Strip (WARLS) protocol removing old 490 LEDs limit https://github.com/Aircoookie/WLED/wiki/UDP-Realtime-Control → #691

- Live update WLED/udpraw LEDs number #564
- ArtNet LED Controller: add toggle to prevent pixel color data split across two artnet universes. Fixes issue #657 → #691
- Workaround for critical Rpi udev bug affecting serial ports #583
Core:
- Refactoring. Migration to C++ Smart Pointers. Move almost all main objects management under control of modern C++ smart pointers, fully control complicated life-cycle and ownership of HyperHDR components #691
- New interface: removed ancient Font Awesome 4 (so 2017...) Migrate to SVG: Bootstrap Icons and Google Material Icons/Symbols #605
- New features: stop processing when user has locked the system #737
- Remove folders nesting #363
- Improved headers including for faster compilation #691
- Pause the USB grabber when all LEDs are off to reduce load #608
- Use optional system libs for compiling #541
- Do not use TurboJPEG for RGB during calibration #508
- Make bonjour use logging utilities. Thanks @nurikk #529
- glibc requirements for DEB installer #402
Platform support:
- SD images are available again and are based on Debian Bullseye, so they will not fit RPi 5: use the official Raspberry Pi installer for this board. It is explained here: link1
