The problem is that the minimum protocols were changed to SMBv2 at
4.11.0 and a lot of the SMBv1 parameters were deprecated at 4.13.0

Then when 'WHATSNEW.txt' was created for 4.14.0rc4, it relied heavy on
the WHATSNEW.txt for 4.13.0, too heavily in fact, because it contained
most of the contents of the 4.13.0 one. The old parts from the 4.13.0
file were removed from the 4.14.0 one when it was released, that one is
the one to read.
