@ -121,6 +121,9 @@ Nazara Engine:
- Added ObjectLibrary::Clear method
- ⚠️ StackArray class and macro was moved from Core/MemoryHelper.hpp to Core/StackArray.hpp
- ⚠️ Renamed NazaraStackAllocation[NoInit] macro to NazaraStackArray[NoInit]
- Added StackVector class
- ⚠️ Removed Vector[2|3]::Distancef method and made Distance method templated
- Added Vector2::Distance static method
Nazara Development Kit:
- Added ImageWidget (#139)
