## Upgrades and changes
* Update _Tor Browser_ to 7.5.
* Update _Linux_ to 4.14.13 and the microcode firmware for AMD to mitigate Spectre.
* Update _Thunderbird_ to 52.5.
## Fixed problems
* Fix printing to a PDF in _Tor Browser_. ([#13403](
https://labs.riseup.net/code/issues/13403) and [#15024](
https://labs.riseup.net/code/issues/15024))
* Fix the opening of the **Applications** menu when the time synchronization changed the clock in the past. ([#14250](
https://labs.riseup.net/code/issues/14250))
* Fix the opening of the documentation included in Tails for many non-English languages. ([#15160](
https://labs.riseup.net/code/issues/15160))
* Fix translations of the time synchronization and "_Tor is ready_" notifications. ([#13437](
https://labs.riseup.net/code/issues/13437))
* Remove the code to migrate from _Claws Mail_ that was preventing _Thunderbird_ to start in some cases. ([#12734](
https://labs.riseup.net/code/issues/12734))
For more details, read our [changelog](
https://git-

# Known issues
* Debug and error messages appear when starting Tails, including an alarming message about a _kernel BUG_.
These messages do not affect the safety of Tails.
* In _Tails Installer_, it is only possible to select an ISO image when choose **Use a downloaded Tails ISO image** when running Tails in English. For other language, the file chooser button remains inactive:
* The documentation shipped in Tails doesn't open in _Tor Browser_ anymore. The warning page of the _Unsafe Browser_ also lacks graphical design. ([#14962](
https://labs.riseup.net/code/issues/14962) and [Tor #24243](
https://bugs.torproject.org/24243))
