New Release: Tor Browser 8.5a11

Tor Browser 8.5a11 is now available from the Tor Browser Alpha download page and also from our

There's a new release candidate available for download. If you build Tor from source, you can download the source code for 0.4.0.4-rc from dist.torproject.org (pgp signature). Packages should be available over the coming weeks, with a new alpha Tor Browser release by early next week.

Remember, this isn't the stable release yet. You should only run this if you'd like to find and report more bugs than usual.

Tor 0.4.0.4-rc is the first release candidate in its series; it fixes several bugs from earlier versions, including some that had affected stability, and one that prevented relays from working with NSS.

Changes in version 0.4.0.4-rc - 2019-04-11

Major bugfixes (NSS, relay):
- When running with NSS, disable TLS 1.2 ciphersuites that use SHA384 for their PRF. Due to an NSS bug, the TLS key exporters for these ciphersuites don't work -- which caused relays to fail to handshake with one another when these ciphersuites were enabled. Fixes bug 29241; bugfix on 0.3.5.1-alpha.
Minor features (bandwidth authority):
- Make bandwidth authorities ignore relays that are reported in the bandwidth file with the flag "vote=0". This change allows us to report unmeasured relays for diagnostic reasons without including their bandwidth in the bandwidth authorities' vote. Closes ticket 29806.
- When a directory authority is using a bandwidth file to obtain the bandwidth values that will be included in the next vote, serve this bandwidth file at /tor/status-vote/next/bandwidth. Closes ticket 21377.

How Bandwidth Scanners Monitor The Tor Network

The Tor network is comprised of thousands of volunteer-run relays around the world, and millions of people rely on it for privacy and freedom online everyday.
