Simon Ser just published Wayland Protocols 1.49, the latest version of the core Wayland protocol definitions. This release introduces improved multi-GPU support, which is intended to enhance how multiple graphics processing units are managed within the Wayland display environment. Additionally, Wayland Protocols 1.49 adds support for Windows BT.2100, enabling better handling of high dynamic range (HDR) content, particularly relevant for displays that adhere to this wider color gamut and higher luminance standard. This update provides foundational improvements for display server implementations leveraging Wayland.
