@ -43,6 +43,14 @@ Breaking Changes:
- ImGui::TreeAdvanceToLabelPos() -> use ImGui::SetCursorPosX(ImGui::GetCursorPosX() + ImGui::GetTreeNodeToLabelSpacing());
- ImFontAtlas::CustomRect -> use ImFontAtlasCustomRect
- ImGuiColorEditFlags_RGB/HSV/HEX -> use ImGuiColorEditFlags_DisplayRGB/HSV/Hex
- Removed io.ImeSetInputScreenPosFn() in favor of more flexible io.SetPlatformImeDataFn() for IME support.
Because this field was mostly only ever used by Dear ImGui internally, not by backends nor the vast majority
of user code, this should only affect a very small fraction for users who are already very IME-aware.
- Obsoleted 'void* io.ImeWindowHandle' in favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'.
This removes an incompatibility between 'master' and 'multi-viewports' backends and toward enabling
better support for IME. Updated backends accordingly. Because the old field is set by existing backends,
we are keeping it (marked as obsolete).

which would makes the draw operation of some backends assert (e.g. Metal with debugging). (#4857)
- Tables, ImDrawListSplitter: Fixed erroneously stripping trailing ImDrawList::AddCallback() when submitted in
last column or last channel and when there are no other drawing operation. (#4843, #4844) [@hoffstadt]
- Platform IME: changed io.ImeSetInputScreenPosFn() to io.SetPlatformImeDataFn() API,
now taking a ImGuiPlatformImeData structure which we can more easily extend in the future.
- Platform IME: moved io.ImeWindowHandle to GetMainViewport()->PlatformHandleRaw.
- Backends: OpenGL3: Fixed a buffer overflow in imgui_impl_opengl3_loader.h init (added in 1.86). (#4468, #4830) [@dymk]
It would generally not have noticeable side-effect at runtime but would be detected by runtime checkers.
- Backends: Metal: Added Apple Metal C++ API support. (#4824, #4746) [@luigifcruz]
