Hi,
Tor Browser 4.5.2-build1 is up at for testing:
https://people.torproject.org/~gk/builds/4.5.2-build1/
This release provides a fix for the Logjam attack (https://weakdh.org/) and updates a number of Tor Browser components: Tor to version 0.2.6.8, 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.
