Tor Browser 7.0a5 发布了，除了一般的Firefox安全和扩展更新之外，这个alpha包含了很多期待已久的特性：
We include Tor 0.3.2.1-alpha,
the first alpha release in the 0.3.2 series, with support for next
generation onion services and a new circuit scheduler, KIST. Thanks
to the work of Jed Davis we are able to ship a content sandbox for
Linux users. While the content sandbox is disabled in Firefox 52 ESR
versions, which Tor Browser is based on, backported patches allow us to
protect our Linux users with the same mechanisms that are provided to
regular Firefox users. The content sandbox is enabled for
Windows users as well. While we still need to clean up our workarounds
to get the sandboxing code to work with our mingw-w64 compiler, we think
the enabled sandbox is ready for a wider testing in our alpha series.
Please give it a try if you can. Although this change should be invisible to users, we switched our build system from gitian/tor-browser-bundle to rbm/tor-browser-build. The build should continue to be reproducible and if you want to do a build yourself the README file in the tor-browser-build repository has some informations.
