[Tails-testers] [Tails-news] Tails 4.2 is out

This release fixes [many security
vulnerabilities](https://tails.boum.org/security/Numerous_security_holes_in_4.1.1/).
You should upgrade as soon as possible.

# Improvements to automatic upgrades

We worked on important improvements to the automatic upgrade feature, which is
still one of your major pain points when using Tails:

* Until now, if your version of Tails was several months old, you sometimes had to do 2 or more automatic upgrades in a row. For example, to upgrade from Tails 3.12 to Tails 3.16, you first had to upgrade to Tails 3.14.

Starting with 4.2, direct automatic upgrades will be available from all prior
versions to the latest version.

* Until now, you could only do a limited number of automatic upgrades, after which you had to do a much more complicated ["manual" upgrade](https://tails.boum.org/doc/upgrade/index.en.html#manual).

Starting with 4.2, you will only have to do a manual upgrade between major
versions, for example to upgrade to Tails 5.0 in 2021.

* We made automatic upgrades use less memory.

* We optimized a bit the size of the download when doing automatic upgrades.

# New features

* We included several command line tools used by [_SecureDrop_](https://securedrop.org/) users to analyze the metadata of leaked documents on computers that cannot use the _[Additional Software](https://tails.boum.org/doc/first_steps/additional_software/index.en.html)_ feature:

    * [_PDF Redact Tools_](https://github.com/firstlookmedia/pdf-redact-tools) to redact and strip metadata from text documents before publishing
    * [_Tesseract OCR_](https://github.com/tesseract-ocr/tesseract) to convert images containing text into a text document
    * [_FFmpeg_](https://ffmpeg.org/) to record and convert audio and video

# Changes and upgrades

* Update _Tor Browser_ to 9.0.3.

* Update _Thunderbird_ to [68.3.0](https://www.mozilla.org/en-US/thunderbird/68.3.0/releasenotes/).

* Update _Linux_ to 5.3.15.

# Fixed problems

* Open _~/Persistent/keepassx.kdbx_ by default when starting _KeePassX_. If this database does not exist yet, stop pointing to it in the list of recent databases.
