T56: Settings › Terminal checks for updates, which the owner asked for after 0.1.5: under Ely, a switch, on by default, checks at start and once a day through curl and Gitea's API, and Check now checks at once; the row says what the check found, a newer release brings Download, which opens its page, and one an automatic check finds posts a notification whose press opens it
