@ -48,11 +48,13 @@ Breaking Changes:
- IsKeyDown(), IsKeyPressed(), IsKeyReleased(), GetKeyPressedAmount().
- All backends were updated to use io.AddKeyEvent().
- Backward compatibility:
- Old backends populating those arrays will still work! (for a while)
- Old backends populating those arrays should still work! (for a while)
- Calling e.g. IsKeyPressed(MY_NATIVE_KEY_XXX) will still work! (for a while)
- Those legacy arrays will only be disabled if '#define IMGUI_DISABLE_OBSOLETE_KEYIO' is set in your imconfig.
In a few versions, IMGUI_DISABLE_OBSOLETE_FUNCTIONS will automatically enable IMGUI_DISABLE_OBSOLETE_KEYIO,
so this will be moved into the regular obsolescence path.
- BREAKING: If your custom backend used ImGuiKey as mock native indices (e.g. "io.KeyMap[ImGuiKey_A] = ImGuiKey_A")
this is a use case that will now assert and be breaking for your old backend.
- Transition guide:
- IsKeyPressed(MY_NATIVE_KEY_XXX) -> use IsKeyPressed(ImGuiKey_XXX)
- IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) -> use IsKeyPressed(ImGuiKey_XXX)

- Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent()
- one case won't work with backward compatibility: if your custom backend used ImGuiKey as mock native indices (e.g. "io.KeyMap[ImGuiKey_A] = ImGuiKey_A") because those values are now larger than the legacy KeyDown[] array. Will assert.
- inputs: added io.AddKeyModsEvent() instead of writing directly to io.KeyCtrl, io.KeyShift, io.KeyAlt, io.KeySuper.
- 2022/01/05 (1.87) - inputs: renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum.
- 2022/01/05 (1.87) - removed io.ImeSetInputScreenPosFn() in favor of more flexible io.SetPlatformImeDataFn(). Removed 'void* io.ImeWindowHandle' in favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'.
