  "textContent": "This release is an emergency release to fix important security vulnerabilities in _Tor Browser_.\n\n## Changes and updates\n\n  * Update _Tor Browser_ to 15.0.11, which fixes several vulnerabilities in Firefox 140.10.1.\n\n\n\nWe are not aware of these vulnerabilities being exploited in practice until now.\n\n  * Update _Thunderbird_ to 140.10.0.\n\n  * Stop making it possible to start our ISO images from a USB stick.\n\n\n\n\nSince 2019, we recommend _USB images_ to start Tails from a USB stick, which is by far the most common way of running Tails.\n\nWe still distribute ISO images to start Tails from a DVD or in a virtual machine. Until now, these ISO images worked on USB sticks as well, but provided a degraded experience without automatic upgrades or Persistent Storage.\n\nOur ISO images no longer work on USB sticks to save a few megabytes and prevent confusion for people who use USB sticks.\n\nFor more details, read our changelog.\n\n## Get Tails 7.7.1\n\n### To upgrade your Tails USB stick and keep your Persistent Storage\n\n  * Automatic upgrades are available from Tails 7.0 or later to 7.7.1.\n\n  * If you cannot do an automatic upgrade or if Tails fails to start after an automatic upgrade, please try to do a manual upgrade.\n\n\n\n\n### To install Tails 7.7.1 on a new USB stick\n\nFollow our installation instructions.\n\nThe Persistent Storage on the USB stick will be lost if you install instead of upgrading.\n\n### To download only\n\nIf you don't need installation or upgrade instructions, you can download Tails 7.7.1 directly:\n\n  * For USB sticks (USB image)\n\n  * For DVDs and virtual machines (ISO image)\n\n\n\n\n## Support and feedback\n\nFor support and feedback, visit the Support\nsection on the Tails website.\n\n  * \n          tails\n        \n  * \n          releases\n        \n\n",
