- Moved from the Chrome WebRTC standalone library to the Pion/WebRTC
library in our proxies and clients.
* Published a prototype of sharknado: a flow obfuscator for obfs4 (and
other pluggable transports). Sharknado is a net.Conn wrapper that
injects padding traffic to thwart traffic classification attacks.

distribute Tor Browser links. Give it a shot by sending an email to
gettor at torproject.org and write "windows", "osx", or "linux" in the

* Worked with new obfs4 bridge operators who set up a bridge as part of
our bridge campaign:
So far, we are counting 82 new bridges. Thanks to everyone who

from Karlstad University: <https://bugs.torproject.org/31164>
