Filing into issue trackers

Version 0.7.0 · Released

A thread can now become an issue without anyone leaving the page. Pick the tracker, and the annotation is filed with its text, its priority and a link back to the room — and the issue's URL comes back into the thread so everyone can find it tomorrow. Your token stays in your browser; the room never stores it.
On this page

ADR 0003 built the outbound integrations layer and, in the same breath, ruled out the trackers: storing a GitHub token against a room id would mean anyone holding the share link could write to the repository, and a leaked link would be a leaked credential. That reasoning was right and it has not changed.

What changed is the shape of the answer. A destination's configuration has two halves, and only one of them is the room's business. Where to file is not a secret and the room keeps it; what authorises the filing is, so it stays in the browser of the person doing it. The reviewer who found the bug is the one best placed to describe it, and now they can, without an account and without handing their token to anyone.
