@ -80,6 +80,12 @@ Other Changes:
- Window: Resizing from edges (with io.ConfigResizeWindowsFromEdges Beta flag) extends the hit region
of root floating windows outside the window, making it easier to resize windows. Resize grips are also
extended accordingly so there are no discontinuity when hovering between borders and corners. (#1495, #822)
- Window: Added ImGuiWindowFlags_NoBackground flag to avoid rendering window background. This is mostly to allow
the creation of new flag combinations, as we could already use SetNextWindowBgAlpha(0.0f). (#1660) [@biojppm, @ocornut]
- Window: Added ImGuiWindowFlags_NoDecoration helper flag which is essentially NoTitleBar+NoResize+NoScrollbar+NoCollapse.
- Window: Added ImGuiWindowFlags_NoMouseInputs which is basically the old ImGuiWindowFlags_NoInputs (essentially
we have renamed ImGuiWindowFlags_NoInputs to ImGuiWindowFlags_NoMouseInputs). Made the new ImGuiWindowFlags_NoInputs
encompass both NoMouseInputs+NoNav, which is consistent with its description. (#1660, #787)
- Window, Inputs: Fixed resizing from edges when io.MousePos is not pixel-rounded by rounding mouse position input. (#2110)
- BeginChild(): Fixed BeginChild(const char*, ...) variation erroneously not applying the ID stack
to the provided string to uniquely identify the child window. This was undoing an intentional change

Benefit from better FreeType rasterization, in particular for small fonts.

Natvis file to describe dear imgui types in the Visual Studio debugger.
With this, types like ImVector<> will be displayed nicely in the debugger.
You can include this file a Visual Studio project file, or install it in Visual Studio folder.
