Tor 0.4.0.1 is released. A couple of interesting things are an experimental new padding scheme and a power saving dormant mode. A lot of memory and startup speed optimizations done.
One change that I noticed was for DNS handling. I want to make sure this change does not cause any accidental leaks on the GW:
o Minor bugfixes (DNS):
- Gracefully handle an empty or absent resolve.conf file by falling
back to using “localhost” as a DNS server (and hoping it works).
Previously, we would just stop running as an exit. Fixes bug
21900; bugfix on 0.2.1.10-alpha.
