performance improvements.

# Changes and upgrades

## Major changes to included software

  is more actively developed.

  [[!img keepassxc.png link="no"]]

- Update *OnionShare* from 0.9.2 to 1.3.2, which includes a lot of usability
  improvements.

- Update *MAT* from 0.6.1 to [0.8.0](https://0xacab.org/jvoisin/mat2/blob/master/CHANGELOG.md)

  *MAT* has no graphical interface of its own anymore.

  To clean the metadata of a file:

  1. Open the *Files* browser and navigate to the file that you want to
     clean.

  1. Right-click (on Mac, click with two fingers) on the file.

  1. Choose **Remove metadata**.

- Update *Tor Browser* to 9.0.

- Update *Linux* to 5.3.2. This should also improve the
  support for newer hardware (graphics, Wi-Fi, etc.).

- Update *Enigmail* to 2.0.12 and *gnupg* to 2.2.12, which mitigate
  [OpenPGP certificate flooding](https://dkg.fifthhorseman.net/blog/openpgp-certificate-flooding.html).

- Upgrade most other software, for example:

  - *Audacity* from 2.1.2 to [2.2.2](https://wiki.audacityteam.org/wiki/Audacity_Versions#whatsnew)

  - *GIMP* from 2.8.18 to [2.10.8](https://docs.gimp.org/2.10/en/gimp-introduction-whats-new.html)

  - *Inkscape* from 0.92.1 to [0.92.4](https://inkscape.org/release/inkscape-0.92.4/)

  - *LibreOffice* from 5.2.7 to [6.1.5](https://wiki.documentfoundation.org/ReleaseNotes/6.0)

    <a id="mat"></a>

  - *git* from 2.11.0 to 2.20.1

  - *Tor* to 0.4.1.5.

- Remove *Scribus*.

  You can install *Scribus* again using the
  *[[Additional Software|doc/first_steps/additional_software]]* feature.

## Usability improvements to *Tails Greeter*

We improved various aspects of the usability of *Tails Greeter*,
especially for non-English users:

- To make it easier to select a language, we curated the list of
  proposed languages by removing the ones that had too little
  translations to be useful.

  [[!img languages.png link="no" alt=""]]

- We also simplified the list of keyboard layouts.

- We fixed the **Formats** setting, which was not being applied.

- We prevented additional settings to be applied when clicking on
  **Cancel** or **Back**.

## Performance and usability improvements

- Tails 4.0 starts 20% faster.

- Tails 4.0 requires about 250 MB less of RAM.

- Add support for *Thunderbolt* devices.

- The screen keyboard is easier to use.

  including USB sticks and SSDs.

  volume|doc/first_steps/persistence/copy]].
