Tails 4.15 Anonymous OS Released with Tor Browser 10.0.9 and Thunderbird 78.6

Tails 4.15

The Tails project released today Tails 4.15 as a monthly maintenance release to the amnesic incognito live system based on the Debian GNU/Linux operating system and used for anonymous communications.

Synced with the stable software repositories of the Debian GNU/Linux 10 “Buster” operating system series, Tails 4.15 is powered by Linux kernel 5.9.15 for improved hardware support and comes with updated core applications, including the Tor Browser 10.0.9 anonymous web browser and Mozilla Thunderbird 78.6 email client.

On top of these updates, Tails 4.15 also improves support for Ledger hardware wallets in the Electrum Bitcoin wallet app, adds USB tethering support for devices running Apple’s iOS 14 or later to share mobile data, and clarifies the error message about the size of the USB flash drive shown when starting Tails.

Other than that, the trusted certificate authority used for connecting to the Tails website have been updated, Intel Sound Open Firmware (SOF) and topology binaries were imported from Debian, the uBlock patch was refreshed to fix the devel branch, and the “Upgrading the system” dialog has been updated to appear faster.

Virtual machine support was improved as well and Tails now shows a “Don’t Show Again” button on the notification when starting Tails in a VM. Also, various language translations have been updated. For more details, you can study the full changelog here.

This release also fixes numerous security vulnerabilities that affect Tails 4.14 and previous versions, so it is highly recommended that you upgrade your installations as soon as possible. For new deployments, you can download Tails 4.15 right now from the official website or using the direct download links below.

The next release in the 4.x series will be Tails 4.16, which is expected to hit the streets on February 23rd, 2021. Sometime later this year, the Tails project will release Tails 5.0, a major series based on the upcoming Debian GNU/Linux 11 “Bullseye” operating system and featuring Wayland support by default and boot improvements.

Update 28/01/21: Tails 4.15.1 images were released with updated Sudo package to version 1.8.27-1+deb10u2 to fix the major vulnerability that lets unprivileged users gain root access.
