Home Assistant lets people with older wall displays continue past the unsupported-browser warning. The browser minimums introduced in October had stopped these devices at the launch screen, even where much of a dashboard still worked.
The first visit offers Continue anyway. The warning returns monthly, then also offers Don’t show again; the choice is saved on that device and cleared by logging out. This is an override, not a promise of compatibility. The change was tested in Chromium 66.
