[Tails-testers] [Tails-news] Tails 4.8 is out

This release fixes [many security
vulnerabilities](https://tails.boum.org/security/Numerous_security_holes_in_4.7/).
You should upgrade as soon as possible.

# New features

* We disabled the _Unsafe Browser_ by default and clarified that [the _Unsafe Browser_ can be used to deanonymize you](https://tails.boum.org/doc/anonymous_internet/unsafe_browser/index.en.html#security).

An attacker could exploit a security vulnerability in another application in
Tails to start an invisible _Unsafe Browser_ and reveal your IP address, even
if you are not using the _Unsafe Browser_.

For example, an attacker could exploit a security vulnerability in
_Thunderbird_ by sending you a phishing email that could start an invisible
_Unsafe Browser_ and reveal them your IP address.

Such an attack is very unlikely but could be performed by a strong attacker,
such as a government or a hacking firm.

This is why we recommend that you:

    * Only enable the _Unsafe Browser_ if you need to log in to a captive portal.
    * Always upgrade to the latest version of Tails to fix known vulnerabilities as soon as possible.
  * We added a new feature of the Persistent Storage to save the settings from the Welcome Screen.

This feature is beta and only the additional setting to enable the _Unsafe
Browser_ is made persistent. The other settings (language, keyboard, and other
additional settings) will be made persistent in Tails 4.9 (July 28).

# Changes and updates

* Update _Tor Browser_ to [9.5.1](https://blog.torproject.org/new-release-tor-browser-951).

* Update _Thunderbird_ to [68.9.0](https://www.thunderbird.net/en-US/thunderbird/68.9.0/releasenotes/).

* Update _Linux_ to 5.6.0. This should improve the support for newer hardware (graphics, Wi-Fi, etc.).

# Fixed problems

* Fix the _Find in page_ feature of _Thunderbird_. ([#17328](https://gitlab.tails.boum.org/tails/tails/-/issues/17328))

* Fix shutting down automatically the laptop when resuming from suspend with the Tails USB stick removed. ([#16787](https://gitlab.tails.boum.org/tails/tails/-/issues/16787))

* Notify always when [MAC address spoofing](https://tails.boum.org/doc/first_steps/welcome_screen/mac_spoofing/index.en.html) fails and the network interface is disabled. ([#17779](https://gitlab.tails.boum.org/tails/tails/-/issues/17779))

* Fix the import of OpenPGP public keys in binary format (non armored) from the _Files_ browser.

For more details, read our
[changelog](https://gitlab.tails.boum.org/tails/tails/-/blob/master/debian/changelog).

# Known issues

* Administration passwords set at the Welcome Screen cannot contain most non-english characters, including spaces ([#17779](https://gitlab.tails.boum.org/tails/tails/-/issues/17779)). Because of this you should limit your passwords to only alphanumeric characters (`a-z`, `A-Z`, `0-9`) and the following special characters: `_@%+=:,./-`. Once you have logged in you can change the password however you like using the `passwd` command in a Terminal.

See the list of [long-standing
issues](https://tails.boum.org/support/known_issues/index.en.html).

# Get Tails 4.8
