Marked ✦. Tumbleweed and Leap 16.1 are level with each other, and Repology knows of no distribution anywhere shipping anything newer — as up to date as a package gets.
Older-in-Leap
Leap 16.1 ships an older upstream version than Tumbleweed. This is the ordinary case for a package that moved on after Leap 16.1 branched, and the list worth working through.
Newer-in-Leap
Leap 16.1 ships a newer upstream version than Tumbleweed, which is not supposed to happen — changes are expected to reach Factory first. Usually a package updated straight in Leap 16.1, or one whose version scheme confuses the comparison; either way it is worth a look.
Same
Tumbleweed and Leap 16.1 ship the same upstream version. Only the version is compared, so the rpm release may still differ.

Tumbleweed ships this source package and Leap 16.1 does not.
