The monthly Tails ISO releases continue with version 4.19, a regular updated ISO release based on the Debian GNU/Linux 10 ?Buster? repositories and including up-to-date components like the Tor Browser 10.0.17 anonymous web browser based on Mozilla Firefox 78.11, and Mozilla Thunderbird 78.10.0 email client. While the new Tor Connection wizard didn?t make it into this release, Tails 4.19 introduces password feedback for sudo when typing an administration password with sudo in a terminal emulator, and improves the automatic upgrade functionality by removing a security feature that prevented the Tails Upgrader from checking for updates.
