June 2026 monthly summary for google/dawn: Focused on delivering native Wayland surface support by default and stabilizing Linux standalone builds. Implemented a default toggle for Wayland when running on Linux, preserved compatibility with X11/XWayland, and fixed a GLFW backend edge-case to ensure builds do not fail when Wayland is unavailable in the GLFW GN target. These changes reduce friction for Wayland-enabled desktops and improve rendering integration while maintaining configurability for downstream users.

May 2026 monthly summary focusing on portability of build tooling, test reliability, and robust request handling across core components. Key kernel build improvements in sysprog21/lkmpg enable out-of-tree module builds across diverse environments: switching to a relative prebuilt tarball path and packaging objtool when CONFIG_OBJTOOL is enabled, plus GCC 15+ compatibility adjustments. Stabilized QEMU test mode by ensuring stdin is redirected from /dev/null when stdout is piped, preventing tcsetattr() on non-terminal terminals and reducing flaky test runs. In Jenkins Stapler, added a guard in getFileItem2 for non-multipart requests to prevent NullPointerExceptions and introduced tests to verify null returns when Content-Type is absent, improving robustness of file upload handling. These changes reduce environment-dependent failures, improve CI reliability, and enhance runtime stability for file uploads and kernel/module builds.
