Hi and welcome to the openSUSE Forums!
Apparently you are already running the current version, so unless you experience other problems we should assume that the update process actually did its work one way or another…
Please remember to always use “zypper dup” with Tumbleweed, since “zypper up” occasionally might leave you with a corrupt system.
700MB is not unusual with Tumbleweed (every snapshot is in fact a new release). Files go to /var/cache/zypp/packages and remain there until they are installed, unless you specified the --keep-packages option when setting up your repositories.
Maybe those files were installed while the system looked “busy” or during the second “zypper dup” attempt…
Adding to Malcolm advice, at the time I wrote my previous comment the “current” release was still 20171114; the next one and “current” as I write this,** 20171115**, was published some 5 hours later (at least on the mirrors for Italy, might be slightly different on Asian mirrors).
See http://download.opensuse.org/tumbleweed/iso/
If that is so, then I just tested, today:
Shouldnt it be either: 20171117 or **20171116
Or how should I confirm? As zypper ref doesnt inform me.

Thankyou
“zypper ref” refreshes the cached contents of the repositories but doesn’t install anything. As Malcolm wrote, you need a “zypper dup” to install the new files available; afterwards, you should be able to see an updated /etc/os-release on your system.
