- Context: Removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions() and shared by all contexts. (#1565, #586, #992, #1007, #1558)
- Context: You may pass a ImFontAtlas to CreateContext() to specify a font atlas to share. Shared font atlas are not owned by the context and not destroyed along with it.
- Context: Added IMGUI_DISABLE_DEFAULT_ALLOCATORS to disable linking with malloc/free. (#1565, #586, #992, #1007, #1558)
- IO: Added io.ConfigFlags for user application to store settings for imgui and for the back-end (currently: _NavEnableKeyboard, _NavEnableGamepad, _NavEnableSetMousePos, _NoMouseCursorChange).
- IO: Added io.ConfigFlags for user application to store settings for imgui and for the back-end:
- ImGuiConfigFlags_NavEnableKeyboard: Enable keyboard navigation.
- ImGuiConfigFlags_NavEnableGamepad: Enable gamepad navigation (provided ImGuiBackendFlags_HasGamepad is also set by back-end).
- ImGuiConfigFlags_NavEnableSetMousePos: Instruct navigation to move the mouse cursor. May be useful on TV/console systems where moving a virtual mouse is awkward.
- ImGuiConfigFlags_NoMouseCursorChange: Instruct back-end to not alter mouse cursor shape and visibility (by default the example back-end use mouse cursor API of the platform when available)
- ImGuiConfigFlags_NoMouse: Instruct imgui to clear mouse position/buttons in NewFrame(). This allows ignoring the mouse information passed by the back-end.
- ImGuiConfigFlags_IsSRGB, ImGuiConfigFlags_IsTouchScreen: Flags for general application use.
- IO: Added io.BackendFlags for back-end to store its capabilities (currently: _HasGamepad, _HasMouseCursors, _HasSetMousePos). This will be used more in the next version.
- IO: Added ImGuiKey_Insert, ImGuiKey_Space keys. Setup in all example bindings. (#1541)
- IO: Added Horizontal Mouse Wheel support for horizontal scrolling. (#1463) [@tseeker]
