This release fixes [[many security
issues|security/Numerous_security_holes_in_2.3]] and users should
upgrade as soon as possible.
[[!toc levels=1]]
# Changes
## New features
- We enabled the automatic account configuration of *Icedove* which
discovers the correct parameters to connect to your email provider
based on your email address. We improved it to rely only on secure
protocol and we are working on sharing these improvements with Mozilla
so that users of *Thunderbird* outside Tails can benefit from them as well.

## Upgrades and changes
- Update *Tor Browser* to
[6.0](, based
on Firefox 45.
- Remove the preconfigured `#tails` IRC channel. [[Join us on XMPP
- Always display minimize and maximize buttons in titlebars.
([[!tails_ticket 11270]])
- Remove *GNOME Tweak Tool* and *hledger*. You can add them back using
the [[*Additional software
persistence feature.
- Use secure HKPS OpenPGP key server in *Enigmail*.
- Harden our firewall by rejecting `RELATED` packets and restricting Tor
to only send `NEW` TCP `syn` packets. ([[!tails_ticket 11391]])
- Harden our kernel by:
* Setting various security-related kernel options: `slab_nomerge slub_debug=FZ
mce=0 vsyscall=none`. ([[!tails_ticket 11143]])
* Removing the <span class="filename">.map</span> files of the kernel.

## Fixed problems
- Update the *DRM* and *Mesa* graphical libraries. This should fix
recent problems with starting Tails on some hardware. ([[!tails_ticket 11303]])
- Some printers that stopped working in Tails 2.0 should work again.
([[!tails_ticket 10965]])
- Enable Packetization Layer Path MTU Discovery for IPv4. This should
make the connections to `obfs4` Tor bridges more reliable. ([[!tails_ticket 9268]])
- Remove our custom ciphers and MACs settings for SSH. This should fix
connectivity issues with other distributions such as OpenBSD.
([[!tails_ticket #7315]])
- Fix the translations of *Tails Upgrader*. ([[!tails_ticket 10221]])
- Fix displaying the details of a circuit in *Onion Circuits* when using
Tor bridges. ([[!tails_ticket 11195]])
For more details, read our [changelog](
