@ -41,6 +41,7 @@ Other Changes:
- InputText: added experimental io.ConfigInputTextEnterKeepActive feature to make pressing
Enter keep the input active and select all text.
- Nav: Fixed moving/resizing window with gamepad or keyboard when running at very high framerate.
- Misc: io.Framerate moving average now converge in 60 frames instead of 120. (#5236, #4138)
- Backends: Metal: Use __bridge for ARC based systems. (#5403) [@stack]
- Backends: Metal: Add dispatch synchronization. (#5447) [@luigifcruz]
