嗯，用户让我帮忙总结一下这篇文章的内容，控制在100字以内，而且不需要用“文章内容总结”之类的开头，直接写描述就行。首先，我得仔细阅读这篇文章，看看主要讲了什么。 看起来这篇文章是关于Tails 7.4版本的更新说明。里面提到了新增的功能、更改和更新、修复的问题以及如何升级或安装新版本。新增功能主要是持久化语言和格式设置，这样用户重启Tails时会自动应用这些设置。这点挺重要的，可能对用户体验有帮助。 然后是更新的部分，Tor Browser、Thunderbird和Linux内核都升级了版本。还提到了不再支持BitTorrent v1下载，转向v2可能会有安全问题，团队觉得不值得投入额外资源维护。这点可能对依赖BitTorrent下载的用户有影响。 修复的问题有几个，比如打开加密文件的问题、VeraCrypt解锁时的崩溃以及时间格式的一致性。这些都是比较具体的bug修复，提升了软件的稳定性和用户体验。 接下来是升级和安装指南，包括自动升级和手动升级的方法，还有安装新版本时需要注意的事项，比如持久化存储会被丢失。这部分信息对用户来说很重要，尤其是那些已经使用Tails一段时间的用户。 最后是支持和反馈的部分，引导用户去官方网站寻求帮助或提供反馈。 现在我需要把这些信息浓缩到100字以内。要抓住重点：新增功能、主要更新、修复的问题以及升级方式。同时要确保语言简洁明了。 可能会这样组织：首先提到新增功能和更新内容，然后提到移除BitTorrent v1支持和一些修复的问题，最后说明如何升级或安装新版本。 比如：“Tails 7.4新增持久化语言和格式设置功能，并更新了Tor Browser、Thunderbird和Linux内核。移除BitTorrent v1下载支持，并修复了多个问题。提供自动和手动升级选项及新安装指南。” 这样大概在100字左右，并且涵盖了主要的信息点。 </think> Tails 7.4新增持久化语言和格式设置功能，并更新了Tor Browser、Thunderbird和Linux内核。移除BitTorrent v1下载支持，并修复了多个问题。提供自动和手动升级选项及新安装指南。 2026-1-15 00:0:0 Author: blog.torproject.org(查看原文) 阅读量:2 收藏
New feature
Persistent language and formats
You can now save your language, keyboard layout, and formats from the Welcome Screen to the USB stick. These settings will be applied automatically when restarting Tails.
If you turn on this option, your language and formats settings are saved unencrypted on the USB stick to help you type the passphrase of your Persistent Storage more easily.
Changes and updates
Update Tor Browser to 15.0.4.
Update Thunderbird to 140.6.0.
Update the Linux kernel to 6.12.63.
Drop support for BitTorrent download.
With the ongoing transition from BitTorrent v1 to v2, the BitTorrent v1 files that we provided until now can become a security concern. We don't think that updating to BitTorrent v2 is worth the extra migration and maintenance cost for our team.
Direct download from one of our mirrors is usually faster.
Fixed problems
Fix opening .gpg encrypted files in Kleopatra when double-clicking or selecting Open with Kleopatra from the shortcut menu. (#21281)
Fix the desktop crashing when unlocking VeraCrypt volumes with a wrong password. (#21286)
Use 24-hour time format consistently in the top navigation bar and the lock screen. (#21310)
For more details, read our changelog.
