For the past year, we have been collecting feedback on how we can make
Tor Browser work better for you.

Tor Browser 8.0, our first stable release based on Firefox 60 ESR, is
now available from the Tor Browser Project page [1] and also from our
distribution directory [2]. This release is all about users first.

Tor Browser 8.0 comes with a series of user experience improvements that
address a set of long-term Tor Browser issues you’ve told us about. To
meet our users' needs, Tor Browser has a new user onboarding experience;
an updated landing page that follows our styleguide [3]; additional
language support; and new behaviors for bridge fetching, displaying a
circuit, and visiting .onion sites.

_New User Onboarding_

For the most part, using Tor is like using any other browser (and it is
based on Firefox), but there are some usage differences and cool things
happening behind the scenes that users should be aware of. Our new
onboarding experience aims to better let you know about unique aspects
of Tor Browser and how to maximize those for your best browsing experience.

_Improved Bridge Fetching_

For users where Tor is blocked, we have previously offered a handful of
bridges in the browser to bypass censorship. But to receive additional
bridges, you had to send an email or visit a website, which posed a set
of problems. To simplify how you request bridges, we now have a new
bridge configuration flow when you when you launch Tor. Now all you
have to do is solve a captcha in Tor Launcher, and you’ll get a bridge
IP. We hope this simplification will allow more people to bypass
censorship and browse the internet freely and privately. [6]

_Better Language Support_

Millions of people around the world use Tor, but not everyone has been
able to use Tor in their language. In Tor Browser 8, we’ve added
resources and support for nine previously unsupported languages: Catalan,
Irish, Indonesian, Icelandic, Norwegian, Danish, Hebrew, Swedish, and
Traditional Chinese.

Apart from those highlights, a number of other component and toolchains
got an update for this major release. In particular, we now ship Tor with OpenSSL 1.0.2p and Libevent 2.1.8. Moreover, we switched
to the pure WebExtension version of NoScript (version which
we still need to provide the security slider functionality. Additionally,
we start shipping 64bit builds for Windows users which should enhance
Tor Browser stability compared to the 32bit bundles.

Providing this many improvements for our users could only be possible
with collaboration between the Tor Browser team and Tor's UX team,
Community team, Services Admin team, and our volunteers. We would like
to thank everyone for working hard over the past year to bring all
these new features to our users.

_Known Issues_

We already collected a number of unresolved bugs since Tor Browser
7.5.6 and tagged them with our ff60-esr keyword [7] to keep them on our
radar. The most important ones are listed below:

    7: https://trac.torproject.org/projects/tor/query?status=!closed&keywords=~ff60-esr

  * WebGL is broken right now

  * We disable Stylo on macOS due to reproducibility issues [8] we need
    to investigate and fix. This will likely not get fixed for Tor Browser 8,
    as we need some baking time on our nightly/alpha channel before we
    are sure there are no reproducibility/stability regressions. The
    tentative plan is to get it ready for Tor Browser 8.5.

Note: This release is signed with a new GPG subkey as the old one expired
a couple of days ago. You might need to refresh your copy of the public
part of the Tor Browser signing key before doing the verification. The
fingerprint of the new subkey is:
