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.
- 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function (will obsolete).
- 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API
- 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive.
- 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead.
- 2015/03/17 (1.36) - renamed GetItemRectMin()/GetItemRectMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function (will obsolete).
