Changes in version 0.2.2.7-alpha - 2010-01-19
o Major features (performance):
- When choosing which cells to relay first, we can now favor circuits
that have been quiet recently, so as to get lower latency for
low-volume circuits. By default, relays enable or disable this
feature based on a setting in the consensus. Preliminary testing
suggests that this should make the network feel faster as more relays
use it. You can override this default by using the new
"CircuitPriorityHalflife" config option. Design and code by Ian
Goldberg, Can Tang, and Chris Alexander.

- Add separate per-conn write limiting to go with the per-conn read
limiting. We added a global write limit in Tor 0.1.2.5-alpha,
but never per-conn write limits.

Changes in version 0.2.1.21 - 2009-12-21
Tor 0.2.1.21 fixes an incompatibility with the most recent OpenSSL
library. If you use Tor on Linux / Unix and you're getting SSL
renegotiation errors, upgrading should help. We also recommend an
upgrade if you're an exit relay.
o Major bugfixes:
- Work around a security feature in OpenSSL 0.9.8l that prevents our
handshake from working unless we explicitly tell OpenSSL that we
are using SSL renegotiation safely. We are, of course, but OpenSSL
0.9.8l won't work unless we say we are.
- Avoid crashing if the client is trying to upload many bytes and the
circuit gets torn down at the same time, or if the flip side
happens on the exit relay. Bugfix on 0.2.0.1-alpha; fixes bug 1150.
o Minor bugfixes:
- Do not refuse to learn about authority certs and v2 networkstatus
documents that are older than the latest consensus. This bug might
have degraded client bootstrapping. Bugfix on 0.2.0.10-alpha.
Spotted and fixed by xmux.
- Fix a couple of very-hard-to-trigger memory leaks, and one hard-to-
trigger platform-specific option misparsing case found by Coverity
Scan.
- Fix a compilation warning on Fedora 12 by removing an impossible-to-
trigger assert. Fixes bug 1173.
Changes in version 0.2.2.6-alpha - 2009-11-19
Tor 0.2.2.6-alpha lays the groundwork for many upcoming features:
support for the new lower-footprint "microdescriptor" directory design,
future-proofing our consensus format against new hash functions or
other changes, and an Android port. It also makes Tor compatible with
the upcoming OpenSSL 0.9.8l release, and fixes a variety of bugs.
o Major features:
- Directory authorities can now create, vote on, and serve multiple
parallel formats of directory data as part of their voting process.

Changes in version 0.2.1.20 - 2009-10-15
Tor 0.2.1.20 fixes a crash bug when you're accessing many hidden
services at once, prepares for more performance improvements, and
fixes a bunch of smaller bugs.
The Windows and OS X bundles also include a more recent Vidalia,
and switch from Privoxy to Polipo.
The OS X installers are now drag and drop. It's best to un-install
Tor/Vidalia and then install this new bundle, rather than upgrade. If
you want to upgrade, you'll need to update the paths for Tor and Polipo
in the Vidalia Settings window.
o Major bugfixes:
- Send circuit or stream sendme cells when our window has decreased
by 100 cells, not when it has decreased by 101 cells. Bug uncovered
by Karsten when testing the "reduce circuit window" performance
patch. Bugfix on the 54th commit on Tor -- from July 2002,
before the release of Tor 0.0.0. This is the new winner of the
oldest-bug prize.
- Fix a remotely triggerable memory leak when a consensus document
contains more than one signature from the same voter. Bugfix on
0.2.0.3-alpha.
- Avoid segfault in rare cases when finishing an introduction circuit
as a client and finding out that we don't have an introduction key
for it. Fixes bug 1073. Reported by Aaron Swartz.
o Major features:
- Tor now reads the "circwindow" parameter out of the consensus,
and uses that value for its circuit package window rather than the
default of 1000 cells. Begins the implementation of proposal 168.
o New directory authorities:
- Set up urras (run by Jacob Appelbaum) as the seventh v3 directory
authority.
- Move moria1 and tonga to alternate IP addresses.
o Minor bugfixes:
- Fix a signed/unsigned compile warning in 0.2.1.19.
- Fix possible segmentation fault on directory authorities. Bugfix on
0.2.1.14-rc.
- Fix an extremely rare infinite recursion bug that could occur if
we tried to log a message after shutting down the log subsystem.
Found by Matt Edman. Bugfix on 0.2.0.16-alpha.
- Fix an obscure bug where hidden services on 64-bit big-endian
systems might mis-read the timestamp in v3 introduce cells, and
refuse to connect back to the client. Discovered by "rotor".
Bugfix on 0.2.1.6-alpha.
- We were triggering a CLOCK_SKEW controller status event whenever
we connect via the v2 connection protocol to any relay that has
a wrong clock. Instead, we should only inform the controller when
it's a trusted authority that claims our clock is wrong. Bugfix
on 0.2.0.20-rc; starts to fix bug 1074. Reported by SwissTorExit.
- We were telling the controller about CHECKING_REACHABILITY and
REACHABILITY_FAILED status events whenever we launch a testing
circuit or notice that one has failed. Instead, only tell the
controller when we want to inform the user of overall success or
overall failure. Bugfix on 0.1.2.6-alpha. Fixes bug 1075. Reported
by SwissTorExit.
- Don't warn when we're using a circuit that ends with a node
excluded in ExcludeExitNodes, but the circuit is not used to access
the outside world. This should help fix bug 1090. Bugfix on
0.2.1.6-alpha.
- Work around a small memory leak in some versions of OpenSSL that
stopped the memory used by the hostname TLS extension from being
freed.
o Minor features:
- Add a "getinfo status/accepted-server-descriptor" controller
command, which is the recommended way for controllers to learn
whether our server descriptor has been successfully received by at
least on directory authority. Un-recommend good-server-descriptor
getinfo and status events until we have a better design for them.
