Foo.__new__ is what species of method?

Howdy all,
The Python reference says of a class ‘__new__’ method::
object.__new__(cls[, ...])
Called to create a new instance of class cls. __new__() is a static
method (special-cased so you need not declare it as such) that takes
the class of which an instance was requested as its first argument.
<URL:https://docs.python.org/3/reference/datamodel.html#object.__new__>
But a “static method” is described, elsewhere in the documentation
<URL:https://docs.python.org/3/library/functions.html#staticmethod>, as
“A static method does not receive an implicit first argument”.
What the ‘__new__’ documentation describes would match a “class method”
<URL:https://docs.python.org/3/library/functions.html#classmethod>
“A class method receives the class as implicit first argument”.
I suspect this a bug in the reference documentation for ‘__new__’, and
it should instead say “__new__ is a class method …”. Am I wrong?
