A new release for the stable Tor Browser is available from the Tor Browser Project page and also from our distribution directory.

Tor Browser 4.5.2 provides a fix for the Logjam attack (https://weakdh.org/) and updates a number of Tor Browser components: Tor to version 0.2.6.9, Torbutton to version 1.9.2.6, NoScript to version 2.6.9.26 and HTTPS-Everywhere to version 5.0.5. Moreover, it fixes a possible crash on Linux and avoids breaking the Add-ons page if Torbutton is disabled.

Here is the complete changelog since 4.5.1:
