v0.8.4 is a hotfix for v0.8.3. The one that mattered on the floor: marking an operation complete could fail with an error, leaving operators stuck at the last step of a job. That path is fixed, and finishing a job goes through in one tap.
Two smaller fixes ride along. A priority Bullet Card now always sorts to the top of its section and reads with clearer styling, and the empty instruction box no longer renders when an operation has no instruction note.
For self-hosters, database schema updates now apply automatically when you deploy a new version, so the app and its database stay in step after an update.
