Type conversion changes between 2.1.0dev and 2.1.0 #236

I have a method with the signature
Memory.GetActive(out int s32MemId)
Memory.GetActive(out System.IntPtr ptr)

With 2.1.0dev it was possible to call

_,out=obj.Memory.GetActive(0)

But this now returns

TypeError: No method matches given arguments

and I have to do:

_,out=obj.Memory.GetActive(System.Int32(0))

What changed and why did it change (i did not find something about this change)?
The new code ist much more verbose, is it possible to get the old behaviour back?
