Changes in version 0.2.0.3-alpha - 2007-07-29
o Major features:
- The first pieces of our "bridge" design for blocking-resistance
are implemented. People can run bridge directory authorities;
people can run bridges; and people can configure their Tor clients
with a set of bridges to use as the first hop into the Tor network.
See http://archives for details.
- Create listener connections before we setuid to the configured
User and Group. Now you can choose port values under 1024, start
Tor as root, and have Tor bind those ports before it changes to
another UID.
- New ConstrainedSockets option to set SO_SNDBUF and SO_RCVBUF on TCP
sockets. Hopefully useful for Tor servers running on "vserver"
accounts. (Patch from coderman.)
User and Group. Now non-Windows users can choose port values
under 1024, start Tor as root, and have Tor bind those ports
before it changes to another UID. (Windows users could already
pick these ports.)
- Added a new ConstrainedSockets config option to set SO_SNDBUF and
SO_RCVBUF on TCP sockets. Hopefully useful for Tor servers running
on "vserver" accounts. (Patch from coderman.)
- Be even more aggressive about separating local traffic from relayed
traffic when RelayBandwidthRate is set. (Refines proposal 111.)
o Major features (experimental):
- First cut of code for directory authorities to vote on a common
network status document rather than each publishing their own
opinion. This code needs more testing and more corner-case handling
before it's ready for use.
- First cut of code for "v3 dir voting": directory authorities will
vote on a common network status document rather than each publishing
their own opinion. This code needs more testing and more corner-case
handling before it's ready for use.
o Security fixes:
- Directory authorities now call routers Fast if their bandwidth is

- Minor change to organizationName and commonName generation procedures
in certificates, to invalidate some earlier censorware approaches.
This is not a long-term solution, but applying it will give us a bit of
time to look into the epidemiology of countermeasures as they spread.

o Minor features (misc):
- Merge in some (as-yet-unused) IPv6 address manipulation code. (Patch
from croup.)
- The tor-gencert tool now creates all files as readable to the file
creator only, and write-protects the authority identity key.
- The tor-gencert tool for v3 directory authorities now creates all
files as readable to the file creator only, and write-protects
the authority identity key.
- When dumping memory usage, list bytes used in buffer memory
free-lists.
- When running with dmalloc, dump more stats on hup and on exit.

if they generate a network status document that is somehow
malformed.
o Performance improvements:
- Be more aggressive with freeing buffer RAM or putting it on the
free lists.
o Traffic load balancing improvements:
- If exit bandwidth ever exceeds one third of total bandwidth, then
use the correct formula to weight exit nodes when choosing paths.
(Based on patch from Mike Perry.)
- Choose perfectly fairly among routers when choosing by bandwidth and
weighting by fraction of bandwidth provided by exits. Previously, we
would choose with only approximate fairness, and correct ourselves
if we ran off the end of the list. [Bugfix on 0.1.2.x]
o Performance improvements:
- Be more aggressive with freeing buffer RAM or putting it on the

- Use Critical Sections rather than Mutexes for synchronizing threads
on win32; Mutexes are heavier-weight, and designed for synchronizing
between processes.

- Use CRLF line endings properly in NS events.
- Terminate multi-line control events properly. (Original patch from tup.)
