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.
|
||||
|
||||
- 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior
|
||||
- 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing()
|
||||
- 2015/02/01 (1.31) - removed IO.MemReallocFn (unused)
|
||||
- 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions.
