Tor Browser 5.5.1 is now available from the Tor Browser Project page and also from our distribution directory.

Most notably, this release features fixes for regressions caused by our font fingerprinting defense: chinese users should have a functional Tor Browser again and emoji support is restored on OS X and Linux systems (we are still working on a fix for Windows).

Moreover, we fixed an oversight in one of our patches which broke some websites depending heavily on iframes.

The full changelog since 5.5 is:
