Tor 0.2.0.19-alpha makes more progress towards normalizing Tor's TLS
handshake, makes path selection for relays more secure and IP address
guessing more robust, and generally fixes a lot of bugs in preparation
for calling the 0.2.0 branch stable.

Changes in version 0.2.0.19-alpha - 2008-02-09
o Major features:
- Do not include recognizeable strings in the commonname part of
Tor's x509 certificates.
o Major bugfixes:
- If we're a relay, avoid picking ourselves as an introduction point,
a rendezvous point, or as the final hop for internal circuits. Bug
reported by taranis and lodger. Bugfix on 0.1.2.x.
- Patch from "Andrew S. Lists" to catch when we contact a directory
mirror at IP address X and he says we look like we're coming from
IP address X. Bugfix on 0.1.2.x.
o Minor features (security):
- Be more paranoid about overwriting sensitive memory on free(),
as a defensive programming tactic to ensure forward secrecy.
o Minor features (directory authority):
- Actually validate the options passed to AuthDirReject,
AuthDirInvalid, AuthDirBadDir, and AuthDirBadExit.
- Reject router descriptors with out-of-range bandwidthcapacity or
bandwidthburst values.
o Minor features (controller):
- Reject controller commands over 1MB in length. This keeps rogue
processes from running us out of memory.
o Minor features (misc):
- Give more descriptive well-formedness errors for out-of-range
hidden service descriptor/protocol versions.
- Make memory debugging information describe more about history
of cell allocation, so we can help reduce our memory use.
o Deprecated features (controller):
- The status/version/num-versioning and status/version/num-concurring
GETINFO options are no longer useful in the v3 directory protocol:
treat them as deprecated, and warn when they're used.
o Minor bugfixes:
- When our consensus networkstatus has been expired for a while, stop
being willing to build circuits using it. Fixes bug 401. Bugfix
on 0.1.2.x.
- Directory caches now fetch certificates from all authorities
listed in a networkstatus consensus, even when they do not
recognize them. Fixes bug 571. Bugfix on 0.2.0.x.
- When connecting to a bridge without specifying its key, insert
the connection into the identity-to-connection map as soon as
a key is learned. Fixes bug 574. Bugfix on 0.2.0.x.
- Detect versions of OS X where malloc_good_size() is present in the
library but never actually declared. Resolves bug 587. Bugfix
on 0.2.0.x.
- Stop incorrectly truncating zlib responses to directory authority
signature download requests. Fixes bug 593. Bugfix on 0.2.0.x.
- Stop recommending that every server operator send mail to tor-ops.
Resolves bug 597. Bugfix on 0.1.2.x.
- Don't trigger an assert if we start a directory authority with a
private IP address (like 127.0.0.1).
- Avoid possible failures when generating a directory with routers
with over-long versions strings, or too many flags set. Bugfix
on 0.1.2.x.
- If an attempt to launch a DNS resolve request over the control
port fails because we have overrun the limit on the number of
connections, tell the controller that the request has failed.
- Avoid using too little bandwidth when our clock skips a few
seconds. Bugfix on 0.1.2.x.
- Fix shell error when warning about missing packages in configure
script, on Fedora or Red Hat machines. Bugfix on 0.2.0.x.
- Do not become confused when receiving a spurious VERSIONS-like
cell from a confused v1 client. Bugfix on 0.2.0.x.
- Re-fetch v2 (as well as v0) rendezvous descriptors when all
introduction points for a hidden service have failed. Patch from
Karsten Loesing. Bugfix on 0.2.0.x.
o Code simplifications and refactoring:
- Remove some needless generality from cpuworker code, for improved
type-safety.
- Stop overloading the circuit_t.onionskin field for both "onionskin
from a CREATE cell that we are waiting for a cpuworker to be
assigned" and "onionskin from an EXTEND cell that we are going to
send to an OR as soon as we are connected". Might help with bug 600.
- Add an in-place version of aes_crypt() so that we can avoid doing a
needless memcpy() call on each cell payload.
