The Tails development team is working on the next major release of this distribution that many also call Anonymous OS.
Tails 4.0 entered beta recently and is the first release under the Debian 10 Buster system., which means that all or most of the pre-installed packages have been updated to the latest versions to support the newest hardware components, especially graphics cards from AMD and Nvidia, as well as Mac computers.
Tails 4.0 also has Thunderbolt 3 device support, which is now integrated into the latest version of GNOME 3, a graphical environment that will come by default in Tails. It is recommended that users with a Thunderbolt device test the implementation by navigating to Devices> Thunderbolt within the GNOME settings.
On the other hand, Tails 4.0 users will be able to open persistent volumes from other USB with Tails, add the application that manages the files to favorites, show the OpenPGP applet on the left side of the TOR status, change the wallpaper of the login screen, and use the default bookmarks of the Tor browser.
Many applications that came by default in Tails will be removed in Tails 4.0. These include the Scribus publishing application and the Math component of the LibreOffice suite, which can be installed in the Additional Software section. Additionally, the KeePassX password management tool will be replaced by KeePassXC.
Also removed in Tails 4.0 the Home launcher from the desktop and the default Pidgin accounts. You may download Tails 4.0 from the official page, but it is not recommended for business use. The final release arrives on October 22, 2019.
