# [Tails 5.4 is out](
https://tails.boum.org/news/version_5.4/index.en.html)
# Changes and updates
* Harden several aspects of our _Linux_ kernel. ([#18302](
https://gitlab.tails.boum.org/tails/tails/-/issues/18302), [#18858](
https://gitlab.tails.boum.org/tails/tails/-/issues/18858), and [#18886](
https://gitlab.tails.boum.org/tails/tails/-/issues/18886))
* Disable HTTPS-only mode in the _Unsafe Browser_ to make it easier to sign in to Wi-Fi networks.
* Update _Tor Browser_ to [11.5.2](
https://blog.torproject.org/new-release-tor-browser-1152).
* Update _tor_ to 0.4.7.10.
* Update the _Linux_ kernel to 5.10.136. This should improve the support for newer hardware: graphics, Wi-Fi, and so on. It will also fix an important vulnerability ([19081](
https://gitlab.tails.boum.org/tails/tails/-/blob/master/19081))
