How do i disconnect events?

Events are stacking in my script and i cant use disconnect() because it is deprecated and i tried using Disconnect() to but it also deprecated for some reason even though the wiki sayes it isnt

Declare the event connection as a variable, then use Disconnect() on it, like this:

local ev = workspace.ChildAdded:Connect(function(blabla)
	--blabla
end)

--later
ev:Disconnect()
