You may notice that there is now a LEAP 15.0 Prefix when you post a new thread in the Forums.

Please use it when asking a question about our Superb New Release.

Although Official Release Date as a few days away, openSUSE Leap 15.0 is already out. If you have been running Beta, the latest Dup brought you into the official release.

From this point on, you should now switch to the same method of updating as in Leap 42.3.

That is, from now on, instead of:
Code:
zypper dup
we now use:
Code:
zypper up
to update openSUSE Leap 15.0, or you can use the Software Updater in the Tray/Panel, or use Yast -> Online Update.
