@ -55,6 +55,8 @@ Other Changes:
clipper instance. High-level languages (Lua,Rust etc.) would typically be affected. (#4822)
- IsItemHovered(): added ImGuiHoveredFlags_NoNavOverride to disable the behavior where the
return value is overriden by focus when gamepad/keyboard navigation is active.
- InputText: Fixed pressing Tab emitting two tabs characters because of dual Keys/Chars events being
trickled with the new input queue (happened on some backends only). (#2467, #1336)
- Tables: Fixed incorrect border height used for logic when resizing one of several synchronized
instance of a same table ID, when instances have a different height. (#3955).
- Inputs: Fixed IsMouseClicked() repeat mode rate being half of keyboard repeat rate.
