@ -113,6 +113,8 @@ Other Changes:
- GetMouseDragDelta(): also returns the delta on the mouse button released frame. (#2419)
- GetMouseDragDelta(): verify that mouse positions are valid otherwise returns zero.
- Inputs: Also add support for horizontal scroll with Shift+Mouse Wheel. (#2424, #1463) [@LucaRood]
- Misc: Added IM_MALLOC/IM_FREE macros mimicking IM_NEW/IM_DELETE so user doesn't need to revert
to using the ImGui::MemAlloc()/MemFree() calls directly.
- Examples: OpenGL: Added a dummy GL call + comments in ImGui_ImplOpenGL3_Init() to detect uninitialized
GL function loaders early, and help users understand what they are missing. (#2421)
- Examples: OpenGL3: Minor tweaks + not calling glBindBuffer more than necessary in the render loop.
