I found the following in the man page for smb.conf:

The value of the parameter (a string) is the highest protocol level
           that will be supported by the client.

           Possible values are :

                  •   CORE: Earliest version. No concept of user names.

                  •   COREPLUS: Slight improvements on CORE for efficiency.

                  •   LANMAN1: First modern version of the protocol. Long
                      filename support.

                  •   LANMAN2: Updates to Lanman1 protocol.

                  •   NT1: Current up to date version of the protocol. Used by
                      Windows NT. Known as CIFS.

                  •   SMB2: Re-implementation of the SMB protocol. Used by
                      Windows Vista and later versions of Windows. SMB2 has sub
                      protocols available.

                             •   SMB2_02: The earliest SMB2 version.

                             •   SMB2_10: Windows 7 SMB2 version.

                      By default SMB2 selects the SMB2_10 variant.

                  •   SMB3: The same as SMB2. Used by Windows 8. SMB3 has sub
                      protocols available.

                             •   SMB3_00: Windows 8 SMB3 version.

                             •   SMB3_02: Windows 8.1 SMB3 version.

                             •   SMB3_11: Windows 10 SMB3 version.

                      By default SMB3 selects the SMB3_11 variant.

           Normally this option should not be set as the automatic negotiation
           phase in the SMB protocol takes care of choosing the appropriate
           protocol.

Notice the last paragraph.  Supposidly negotiation is supposed to take place,
meaning that I shouldn't have to do anything.  I added the line in my
usenet-new section with SMB2, but there was no difference.  Something else
is wrong?
