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
