Hi,

For SLE, 15.1 will be supported until 6 months after 15.2 release (so until 
next January/February), with long term support probably going to at least year 
2023. Personally, I plan to upgrade to 15.2 pretty soon after the release.

For distribution upgrades, “zypper dist-upgrade” is required, or for SLE, 
”zypper migration”, i.e. it’s not part of the normal update flow. This might 
be a problem in enterprise setups, but I doubt there is many who would have 
unofficial Wireguard there.
