I don't see this listed anywhere in the Jira Cloud "release notes" (such as they are) but I got back from a week's vacation today and I am seeing sections for "Linked Work Items" and "Child Work Items" on issues even when there are no linked\child issues present.
Is this part of some Rovo hallucination? Is everyone else seeing this? I don't mean to be glib or snarky, but in the 5+ years I have been administering Jira Cloud I cannot remember ever once having an unexpected visual change make me happy.
It's a new feeling, and I like it.
