This release fixes [[many security vulnerabilities|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|doc/upgrade#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* 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
