 // CHANGELOG
 // (minor and older changes stripped away, please see git history for details)
+//  2026-05-19: DPI: ImGui_ImplWin32_EnableDpiAwareness() helper uses SetProcessDpiAwarenessContext() instead of SetThreadDpiAwarenessContext(), fixes DPI scaling issues with e.g. OpenGL. (#9403)
 //  2026-01-28: Inputs: Minor optimization not submitting gamepad input if packet number has not changed (reworked from 2025-09-23 attempt). (#9202, #8556)
 //  2025-12-03: Inputs: handle WM_IME_CHAR/WM_IME_COMPOSITION messages to support Unicode inputs on MBCS (non-Unicode) Windows. (#9099, #3653, #5961)
 //  2025-10-19: Inputs: Revert previous change to allow for io.ClearInputKeys() on focus-out not losing gamepad state.
