How to request a package update for Leap 42.2?

Hi,

I want to request a package update for Leap 42.2. Is there an official way or to do I contact the maintainer personally?

example:
https://build.opensuse.org/package/users/openSUSE:Leap:42.1/engauge-digitizer shows that Dominique Leuenberger and Stephan Kulow maintain the package engauge-digitizer. But on their “home page” the package doesn’t show up in the “involved packages” list. This leaves me utterly confused - please enlighten me.

Hi
Since none of the boxes are checked, then perhaps look at the last person who updated the package…
https://build.opensuse.org/package/view_file/openSUSE:Leap:42.1/engauge-digitizer/engauge-digitizer.changes?expand=1

Or just update yourself and submit…?
