Occasionally introducing changes that are breaking the API. The breakage are generally minor and easy to fix.
Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code.
Also read releases logs https://github.com/ocornut/imgui/releases for more details.
- 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project.
- 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason

- tip: the construct 'IMGUI_ONCE_UPON_A_FRAME { ... }' will run the block of code only once a frame. You can use it to quickly add custom UI in the middle of a deep nested inner loop in your code.
- tip: you can create widgets without a Begin()/End() block, they will go in an implicit window called "Debug"
- tip: you can call Begin() multiple times with the same name during the same frame, it will keep appending to the same window.
- tip: you can call Begin() multiple times with the same name during the same frame, it will keep appending to the same window. this is also useful to set yourself in the context of a window (to get/set other settings)
- tip: you can call Render() multiple times (e.g for VR renders).
- tip: call and read the ShowTestWindow() code for more example of how to use ImGui!

- window: a collapsed window can be stuck behind the main menu bar?
- scrolling: add horizontal scroll

- plot: "smooth" automatic scale over time, user give an input 0.0(full user scale) 1.0(full derived from value)
- plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID)
- file selection widget -> build the tool in our codebase to improve model-dialog idioms
- inputfloat: applying arithmetics ops (+,-,*,/) messes up with text edit undo stack.
- slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
- slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar).
- slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate.
