@ -75,6 +75,9 @@ Other Changes:
tampered with between NewFrame() and EndFrame().
- Misc, Freetype: Fixed support for IMGUI_STB_RECT_PACK_FILENAME compile time directive
in imgui_freetype.cpp (matching support in the regular code path). (#3062) [@DonKult]
- Metrics: Made Tools section more prominent. Showing wire-frame mesh directly hovering the ImDrawCmd
instead of requiring to open it. Added options to disable bounding box and mesh display.
Added notes on inactive/gc-ed windows.
- Demo: Added black and white and color gradients to Demo>Examples>Custom Rendering.
- CI: Added more tests on the continuous-integration server: extra warnings for Clang/GCC, building
SDL+Metal example, building imgui_freetype.cpp, more compile-time imconfig.h settings: disabling
