Changelog
Changelog in the sidebar opens the release notes for the version you are running.
Why it lives in the app
MedJot updates itself. There is no version to install and no release you can choose to skip, so the only useful place to say what changed is inside the thing that changed — next to the feature, on the device it changed on.
When it appears
New notes are published when a release goes out. MedJot never applies an update silently: you are prompted, and you decide when to take it. See Updates and storage.
An update never interrupts a report in progress. Your draft is saved before anything reloads.
If something in a release affected you
Raise it through Feedback & Support — see Getting help. Quote the release if you can; it narrows the search considerably.
If a change removed something you relied on, say so. Removals are decisions, and a decision made without knowing who was using the thing is a decision worth revisiting: Feature requests.
