@ -83,6 +83,8 @@ Other changes:
- IO: Changed io.ClearInputsKeys() specs to also clear current frame character buffer
(what now obsoleted io.ClearInputCharacters() did), as this is effectively the
desirable behavior.
- Misc: Added IMGUI_DISABLE_STB_SPRINTF_IMPLEMENTATION config macro to disable
stb_sprintf implementation when using IMGUI_USE_STB_SPRINTF. (#6626) [@septag]
- Demo: Better showcase use of SetNextItemAllowOverlap(). (#6574, #6512, #3909, #517)
- Demo: Showcase a few more InputText() flags.
- Backends: Made all backends sources files support global IMGUI_DISABLE. (#6601)
