Breaking Changes:
- Removed redirecting functions/enums names that were marked obsolete in 1.66 (September 2018):
- ImGui::SetScrollHere() --> use ImGui::SetScrollHereY()
- ImDrawList: upgraded AddPolyline()/PathStroke()'s "bool closed" parameter to use "ImDrawFlags flags".
The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future.
- bool closed = false --> use ImDrawFlags_None, or 0
- bool closed = true --> use ImDrawFlags_Closed
Difference may not be noticeable for most but zealous type-checking tools may report a need to change.
- ImDrawList: upgraded AddRect(), AddRectFilled(), PathRect() to use general ImDrawFlags instead of ImDrawCornersFlags.
The old ImDrawCornersFlags used an awkward default value of ~0 or 0xF (4 lower bits set) to signify "round all
corners". We still support old flags, but note that the new named flags are opt-out instead of opt-in. [@rokups]
- AddRect(..., rounding, ImDrawCornerFlags_TopLeft) --> AddRect(..., ImDrawFlags_NoRoundCorners ^ ImDrawFlags_NoRoundCornerTL)
- Flags now sanely default to 0 instead of defaulting to ~0 or ImDrawCornerFlags_All, consistent with everywhere else.
- In practice, this shouldn't have an effect as those flags were rarely used.
- All meaningful old uses are supported:
- Default flags will behave the same.
- Use of old named flags will behave the same (but will be obsoleted later)
- Use of hardcoded ~0 or 0xF, previously suggested as a convenience, will behave the same (but will be obsoleted later).
- Not supported:
- Use of hardcoded values between 0x01 and 0x0E not using named flags are NOT supported (will assert).
- Use of new ImDrawFlags together with ImDrawCornerFlags in the same call (will assert).
- Use of rounding > 0.0f along old flags explicitely set as hardcoded 0 would have previously overidden the
rounding value back into "no rounding", whereas it will now behave as "round all corners".
This is technically the only real breaking change which we can't solve automatically.
- ImDrawList: clarified that PathArcTo()/PathArcToFast() won't render with radius < 0.0f. Previously it sorts
of accidentally worked but would lead to counter-clockwise paths which and have an effect on anti-aliasing.
- Moved 'misc/natvis/imgui.natvis' to 'misc/debuggers/imgui.natvis' as we will provide scripts for other debuggers.
- Style: renamed rarely used style.CircleSegmentMaxError (old default = 1.60f)
to style.CircleTessellationMaxError (new default = 0.30f) as its meaning changed. (#3808) [@thedmd]
- Win32+MinGW: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly

Other Changes:
- DragScalar: Fixed crash when using DragScalar() directly (not via common wrapper like DragFloat() etc.)
with ImGuiSliderFlags_AlwaysClamp + only one of either p_min or p_max set. (#3824) [@harry75369]
- Window: Shrink close button hit-testing region when it covers an abnormally high portion of the window visible
area (e.g. when window is collapsed + moved in a corner) to facilitate moving the window away. (#3825)
- Window, Nav: Fixed crash when calling SetWindowFocus(NULL) as the time a new window appears. (#3865) [@nem0]
- Nav: Various fixes for losing gamepad/keyboard navigation reference point when a window reappears or
when it appears while gamepad/keyboard are not being used. (#787)
- Drags: Fixed crash when using DragScalar() directly (not via common wrapper like DragFloat() etc.)
with ImGuiSliderFlags_AlwaysClamp + only one of either p_min or p_max set. (#3824) [@harry75369]
- Drags, Sliders: Fixed a bug where editing value would use wrong number if there were digits right after
format specifier (e.g. using "%f123" as a format string). [@rokups]
- Drags, Sliders: Fixed a bug where using custom formatting flags (',$,_) supported by stb_sprintf.h
would cause incorrect value to be displayed. (#3604) [@rokups]
- Tables: Fixed unaligned accesses when using TableSetBgColor(ImGuiTableBgTarget_CellBg). (#3872)
- IsItemHovered(): fixed return value false positive when used after EndChild(), EndGroup() or widgets using
either of them, when the hovered location is located within a child window, e.g. InputTextMultiline().
This is intended to have no side effects, but brace yourself for the possible comeback.. (#3851, #1370)
- Drag and Drop: can use BeginDragDropSource() for other than the left mouse button as long as the item
has an ID (for ID-less items will add new functionalities later). (#1637, #3885)
- Added GetAllocatorFunctions() to facilitate sharing allocators accross DLL boundaries. (#3836)
- ImFontAtlas: Added 'bool TexPixelsUseColors' output to help backend decide of underlying texture format. (#3369)
This can currently only ever be set by the Freetype renderer.
- imgui_freetype: Added ImGuiFreeTypeBuilderFlags_Bitmap flag to request Freetype loading bitmap data.
- imgui_freetype: Added ImGuiFreeTypeBuilderFlags_Bitmap flag to request Freetype loading bitmap data.
This may have an effect on size and must be called with correct size values. (#3879) [@metarutaiga]
- ImDrawList: PathArcTo() now supports "int num_segments = 0" (new default) and adaptively tesselate.
The adapative tesselation uses look up tables, tends to be faster than old PathArcTo() while maintaining
quality for large arcs (tesselation quality derived from "style.CircleTessellationMaxError") (#3491) [@thedmd]
- ImDrawList: PathArcToFast() also adaptively tesselate efficiently. This means that large rounded corners
in e.g. hi-dpi settings will generally look better. (#3491) [@thedmd]
- ImDrawList: AddCircle, AddCircleFilled(): Tweaked default segment count calculation to honor MaxError
with more accuracy. Made default segment count always even for better looking result. (#3808) [@thedmd]
- ImDrawList: AddCircle, AddCircleFilled(): New default for style.
- Backends: Android: Added native Android backend. (#3446) [@duddel]
- Backends: Win32: Added ImGui_ImplWin32_EnableAlphaCompositing() to facilitate experimenting with
- Backends: Win32: Added ImGui_ImplWin32_EnableAlphaCompositing() to facilitate experimenting with
alpha compositing and transparent windows. (#2766, #3447 etc.).
- Backends: OpenGL, Vulkan, DX9, DX10, DX11, DX12, Metal, WebGPU, Allegro: Rework blending equation to
preserve alpha in output buffer (using SrcBlendAlpha = ONE, DstBlendAlpha = ONE_MINUS_SRC_ALPHA consistently
