Tails 4.4 comes one month after Tails 4.3, which added support for Trezor cryptocurrencies, to update some of the core components and default applications, as well as to address some important security vulnerabilities and other issues reported by users since the previous release. Included in Tails 4.4 are the newest Tor Browser 9.0.6 anonymous web browser, which is based on Mozilla Firefox 68.6.0 ESR, Mozilla Thunderbird 68.5.0 email and news client, as well as the Linux 5.4.19 LTS kernel with better support for newer hardware.
