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

Tor Browser 4.0.2 is based on Firefox ESR 31.3.0, which features important security updates to Firefox. Additionally, it fixes a regression in third party cache isolation (tracking protection) that appeared in 4.0, and prevents JavaScript engine locale leaks.

DirectShow is still disabled by default, though, to give the respective mingw-w64 patch another round of testing.
