  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.
 
- - 2018/01/20 (1.XX) - removed allocator parameters from CreateContext(), they are now setup with SetMemoryAllocators() and shared by all contexts.
+ - 2018/01/20 (1.XX) - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions() and shared by all contexts.
  - 2018/01/11 (1.54) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete).
  - 2018/01/11 (1.54) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete).
  - 2018/01/03 (1.54) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData.
