@ -47,6 +47,8 @@ Breaking Changes:
- style.CurveTessellationMaxError == sqrf(style.CurveTessellationTol).
- ImGuiTextFilter: removed `float width` parameter of `Draw(const char* filter, float width)`:
prefer using `SetNextItemWidth(float)` which is standard. Kept inline redirection function.
- Fonts: renamed `AddRemapChar()` to `AddRemapCodepoint()` (rarely used, marked internal).
(#609, #5748, #9559)
- Backends:
- DirectX12: Removed support for legacy `ImGui_ImplDX12_Init()` signature, which was
obsoleted in 1.91.6 (December 2014), because it needed to forcefully disable support

When you are not sure about an old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files.
