For some reason, the Jenkins page already lists support for 26.x. Maybe it was supposed to say 26.1.x?

Looks like a problem with Paper (as it provides both 2.2 and 2.6 through leafpile). We can probably lift the restriction for now or somehow exclude 2.6? I'm not very familiar with that.

That's correct, should I open a separate issue or something?

NotMyFault · 2026-07-04T14:21:06Z

Looks sane to me.

NotMyFault · 2026-07-04T20:49:02Z

Any objections to merging this PR and letting people test it on the default branch?
