Samba access may appear "broken" in the last build or two - sorry about that. The default has been changed from SMBv3 to a new option of None which will only make sense with Samba 4.7, which these builds are not yet on. There will be a fix in tonight's build, but in the meantime temporarily force SMBv3 if you find your access to Samba content is no longer working.
