Too many changes to list here; most are not visible to client-only
users anyway.
I've tested client and anymous service functions. Couldn't test server
myself. Since noone responded when I asked for testers I'm committing
the update anyway, also because security flaws were reported without
telling whether they apply to the old 0.1.1 branch.
Changes in version 0.1.1.24 - 2006-09-29
o Major bugfixes:
- Allow really slow clients to not hang up five minutes into their
directory downloads (suggested by Adam J. Richter).
- Fix major performance regression from 0.1.0.x: instead of checking
whether we have enough directory information every time we want to
do something, only check when the directory information has changed.
This should improve client CPU usage by 25-50%.
- Don't crash if, after a server has been running for a while,
it can't resolve its hostname.
- When a client asks us to resolve (not connect to) an address,
and we have a cached answer, give them the cached answer.
Previously, we would give them no answer at all.
o Minor bugfixes:
- Allow Tor to start when RunAsDaemon is set but no logs are set.
- Don't crash when the controller receives a third argument to an
"extendcircuit" request.
- Controller protocol fixes: fix encoding in "getinfo addr-mappings"
response; fix error code when "getinfo dir/status/" fails.
- Fix configure.in to not produce broken configure files with
more recent versions of autoconf. Thanks to Clint for his auto*
voodoo.
- Fix security bug on NetBSD that could allow someone to force
uninitialized RAM to be sent to a server's DNS resolver. This
only affects NetBSD and other platforms that do not bounds-check
tolower().
- Warn user when using libevent 1.1a or earlier with win32 or kqueue
methods: these are known to be buggy.
- If we're a directory mirror and we ask for "all" network status
documents, we would discard status documents from authorities
we don't recognize.
Changes in version 0.1.1.22 - 2006-07-05
o Major bugfixes:
- Fix a big bug that was causing servers to not find themselves
reachable if they changed IP addresses. Since only 0.1.1.22+
servers can do reachability testing correctly, now we automatically
make sure to test via one of these.
- Fix to allow clients and mirrors to learn directory info from
descriptor downloads that get cut off partway through.
- Directory authorities had a bug in deciding if a newly published
descriptor was novel enough to make everybody want a copy -- a few
servers seem to be publishing new descriptors many times a minute.
o Minor bugfixes:
- Fix a rare bug that was causing some servers to complain about
"closing wedged cpuworkers" and skip some circuit create requests.
- Make the Exit flag in directory status documents actually work.
While here, patch sample config file to log to syslog per default to make
sure that tor starts as a daemon with the default config.
- maintainer -> tv
Changes (summary):
some major security fixes, including entry guards to protect the
beginning of the circuit, exit enclaves to protect the end, and better
firewall support; a new directory protocol that improves bandwidth use
and keeps clients more up to date; two new directory authorities;
a new ascii-based controller protocol that lets people easily write
applications to interact with Tor; and
many scalability and performance improvements

This is a major update, too many improvements to list here, see
the ChangeLog in the distribution for details.
pkgsrc changes:
-remove dependency on tsocks; this is just one possible way to
make applications use SOCKS; add a hint to MESSAGE
-use the pkgsrc libevent - the NetBSD builtin is old, and tor
complains loudly if it doesn't like the libevent version
-make the rc.d script executable
pkgsrc changes:
- depend on tsocks to allow torification of other applications
- create a user for this application to run as
- install a suitable rc script
ChangeLog says:
o Bugfixes on 0.0.9:
- Fix an assert bug that took down most of our servers: when
a server claims to have 500 GB of bandwidthburst, don't
freak out.
- Don't crash as badly if we have spawned the max allowed number
of dnsworkers, or we're out of file descriptors.
- Block more file-sharing ports in the default exit policy.
- MaxConn is now automatically set to the hard limit of max
file descriptors we're allowed (ulimit -n), minus a few for
logs, etc.
- Give a clearer message when servers need to raise their
ulimit -n when they start running out of file descriptors.
- SGI Compatibility patches from Jan Schaumann.
- Tolerate a corrupt cached directory better.
- When a dirserver hasn't approved your server, list which one.
- Go into soft hibernation after 95% of the bandwidth is used,
not 99%. This is especially important for daily hibernators who
have a small accounting max. Hopefully it will result in fewer
cut connections when the hard hibernation starts.
- Load-balance better when using servers that claim more than
800kB/s of capacity.
- Make NT services work (experimental, only used if compiled in).
Pkgsrc changes:
- make this build under IRIX.
- tor has moved to tor.eff.org
Version changes since 0.0.9.2:
- Backport the cpu use fixes from main branch, so busy servers won't
need as much processor time.
- Work better when we go offline and then come back, or when we
run Tor at boot before the network is up. We do this by
optimistically trying to fetch a new directory whenever an
application request comes in and we think we're offline -- the
human is hopefully a good measure of when the network is back.
- Backport some minimal hidserv bugfixes: keep rend circuits open as
long as you keep using them; actually publish hidserv descriptors
shortly after they change, rather than waiting 20-40 minutes.
- Enable Mac startup script by default.
- Fix duplicate dns_cancel_pending_resolve reported by Giorgos Pallas.
- When you update AllowUnverifiedNodes or FirewallPorts via the
controller's setconf feature, we were always appending, never
resetting.
- When you update HiddenServiceDir via setconf, it was screwing up
the order of reading the lines, making it fail.
- Do not rewrite a cached directory back to the cache; otherwise we
will think it is recent and not fetch a newer one on startup.
- Workaround for webservers that lie about Content-Encoding: Tor
now tries to autodetect compressed directories and compression
itself. This lets us Proxypass dir fetches through apache.
