All the released versions of Samba can still use SMBv1, but it was
deprecated and turned off by default at version 4.11.0 but you can turn
it on again.

If you are still using SMBv1, then I suggest you stop, it is very
insecure. If you must use it (some old machine that can only use
SMBv1), then I suggest you sandbox it somehow.
