  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.
 
+ - 2018/02/15 (1.XX) - ImFont::DisplayOffset.y field defaults to 0 instead of +1.
  - 2018/02/07 (1.60) - reorganized context handling to be more explicit,
                        - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END.
                        - removed Shutdown() function, as DestroyContext() serve this purpose.
