Home Assistant gives owners who serve its interface over HTTPS a choice of updated encryption profiles without silently breaking older clients. Existing installations retain their previous profile; a repair offers a newer one, and a five-minute trial restores the old setting if the change locks the owner out.
The recommended Modern v6 profile requires TLS 1.3, while Intermediate v6 also accepts TLS 1.2 for older devices. New installations default to Modern v6. The network settings explain the choices and identify the older profiles as outdated.
The change concerns Home Assistant’s own web server. Returning to an older Home Assistant release requires restoring a backup because the saved settings use new profile names.
