As a consequence, the version of _Thunderbird_ in Tails was almost always outdated, with known security vulnerabilities.\n\nBy installing Thunderbird as additional\nsoftware, the latest version of _Thunderbird_ is installed automatically from your Persistent Storage each time you start Tails.\n\nIf the **Thunderbird Migration** dialog below appears when you start _Thunderbird_ , it means that Tails successfully installed _Thunderbird_ as additional software.\n\n  * Include the language pack for Mexican Spanish in _Thunderbird_ in addition to the language pack for Spanish from Spain.\n\n\n\nFor more details, read our changelog.\n\n## Get Tails 7.5\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 7.5.\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 7.5 on a new USB stick\n\nFollow our installation instructions:\n\n  * Install from Windows\n\n  * Install from macOS\n\n  * Install from Linux\n\n  * Install from Debian or Ubuntu using the command line and GnuPG\n\n\n\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 7.5 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",
