Weston 16: HDR-ready, improved debugging, and DRM back end features

11 days ago

Weston 16.0 released with improved color management and HDR support, though HDR remains experimental due to lack of tone mapping.
Added interoperability between parametric and ICC profiles, enabling wider color-aware applications and support for HDR displays and clients.
Introduced support for in-shader blending in GL-renderer and new kernel Mode Setting (KMS) uAPI for offloading pre-blend color transformations.
Enhanced Perfetto instrumentation for debugging, providing detailed insights into GL-renderer optimizations, buffer info, and input events.
DRM backend updates include support for new properties like BACKGROUND_COLOR and COLOR_FORMAT, underscan properties, and state reuse optimizations.
Alpha modifier protocol added, allowing clients to set alpha factors for transparency effects without re-rendering content.
Deprecation of remoting and PipeWire plugins, screen-share module, and non-atomic modeset planned for future releases.
