Dec 1, 2025Monthly summary for 2025-12: Delivered critical GLFW3 input handling and stability enhancements in emscripten, aligning pointer lock delta movement with actual input and strengthening safety around event listeners. Implemented safer interoperation by adopting emscripten_html5_remove_event_listener, and fixed non-compliance in glfwMakeContextCurrent, with tests/demos updated to validate behavior across browsers. Result: more reliable WebGL apps with GLFW3 in browser, reduced edge-case bugs, and clearer integration boundaries for client code.

Aug 1, 2025Delivered a critical UI stability improvement for the Emscripten project: ported emscripten-glfw to GLFW 3.4.0.20250824 and fixed resize flicker by delaying resize events until glfwPollEvents, resulting in a smoother user experience and lower defect leakage. This aligns with ongoing GLFW dependency updates and strengthens cross‑platform rendering reliability.

Jun 1, 2025June 2025: Implemented GLFW3 external port integration for the emscripten GLFW port by leveraging Emscripten's external port feature. This refactor points to an external ZIP for the GLFW library, removing internal implementation details, reducing SDK size, and speeding up port file parsing. The change lowers maintenance burden and simplifies future GLFW updates.
