Disclosure up front: we're building this, so this is validating in the open, not a neutral question.
We're building Change Trail, a Jira app that turns change history into a clean "what changed in this release" report : status moves, approvals, who owned what, with an optional view that maps it to SOC 2 / ISO for audit prep.
Before building further, I'd really value a gut check from people who live in Jira:
Honest answers welcome, including "this already exists" or "we don't need this." That's exactly what I'm trying to learn. Happy to share an early-access page with anyone who'd find it useful.
