# [Tails 6.4](
https://tails.net/news/version_6.4/index.en.html)
# New features
## Random seed
Tails now stores a random seed on the USB stick to strengthen all
cryptography.
Having a [secure random number
generator](
https://en.wikipedia.org/wiki/cryptographically%20secure%20pseudorandom%20number%20generator)
is critical to some of the cryptography used in Tails, for example, in the
Persistent Storage, Tor, or HTTPS.
This random seed is stored [outside of the Persistent
Storage](
https://tails.net/contribute/design/random/) so that all users can
benefit from stronger cryptography.
# Changes and updates
* Switch to using HTTPS addresses instead of an onion addresses for the Debian and Tails APT repositories. This makes the [Additional Software](
https://tails.net/doc/persistent_storage/additional_software/index.en.html) feature more reliable.
* Update _Tor Browser_ to [13.0.16](
https://blog.torproject.org/new-release-tor-browser-13016).
* Update the _Tor_ client to 0.4.8.12.
* Update _Thunderbird_ to [115.12.0](
https://www.thunderbird.net/en-US/thunderbird/115.12.0/releasenotes/).
# Fixed problems
* Fix more issues when unlocking the Persistent Storage. ([#20020](
https://gitlab.tails.boum.org/tails/tails/-/issues/20020), [#20344](
https://gitlab.tails.boum.org/tails/tails/-/issues/20344), [#19913](
https://gitlab.tails.boum.org/tails/tails/-/issues/19913))
* Fix connecting to a mobile broadband network on some hardware. ([#20291](
https://gitlab.tails.boum.org/tails/tails/-/issues/20291))
* Enable again the PDF reader of _Thunderbird_ that we disabled in [Tails 6.3](
https://tails.net/news/version_6.3/index.en.html) for security.
* Improve the error message of _Tails Cloner_ when the target USB stick cannot be unmounted because it is being used. ([#19253](
https://gitlab.tails.boum.org/tails/tails/-/issues/19253))
* Fix the homepage of _Tor Browser_ when using the New Identity feature. This removes the error message `Tor Browser blocked your homepage from loading`. ([#20381](
https://gitlab.tails.boum.org/tails/tails/-/issues/20381))
* Remove the redundant dialog when unlocking a VeraCrypt volume using the _Unlock VeraCrypt Volumes_ utility. ([#20281](
https://gitlab.tails.boum.org/tails/tails/-/issues/20281))

[changelog](

# Get Tails 6.4
## To upgrade your Tails USB stick and keep your Persistent Storage
* Automatic upgrades are available from Tails 6.0 or later to 6.4.
You can [reduce the size of the
download](
https://tails.net/doc/upgrade/index.en.html#reduce) of future
automatic upgrades by doing a manual upgrade to the latest version.
* If you cannot do an automatic upgrade or if Tails fails to start after an automatic upgrade, please try to do a [manual upgrade](
https://tails.net/doc/upgrade/index.en.html#manual).
## To install Tails 6.4 on a new USB stick
Follow our installation instructions:
