-Changes in version 0.1.1.19-rc - 2006-05-03
-  o Minor bugs:
-    - Regenerate our local descriptor if it's dirty and we try to use
-      it locally (e.g. if it changes during reachability detection).
-    - If we setconf our ORPort to 0, we continued to listen on the
-      old ORPort and receive connections.
-    - Avoid a second warning about machine/limits.h on Debian
-      GNU/kFreeBSD.
-    - Be willing to add our own routerinfo into the routerlist.
-      Now authorities will include themselves in their directories
-      and network-statuses.
-    - Stop trying to upload rendezvous descriptors to every
-      directory authority: only try the v1 authorities.
-    - Servers no longer complain when they think they're not
-      registered with the directory authorities. There were too many
-      false positives.
-    - Backport dist-rpm changes so rpms can be built without errors.
-
-  o Features:
-    - Implement an option, VirtualAddrMask, to set which addresses
-      get handed out in response to mapaddress requests. This works
-      around a bug in tsocks where 127.0.0.0/8 is never socksified.
-
-
-Changes in version 0.1.1.18-rc - 2006-04-10
-  o Major fixes:
-    - Work harder to download live network-statuses from all the
-      directory authorities we know about. Improve the threshold
-      decision logic so we're more robust to edge cases.
-    - When fetching rendezvous descriptors, we were willing to ask
-      v2 authorities too, which would always return 404.
-
-  o Minor fixes:
-    - Stop listing down or invalid nodes in the v1 directory. This will
-      reduce its bulk by about 1/3, and reduce load on directory mirrors.
-    - When deciding whether a router is Fast or Guard-worthy, consider
-      his advertised BandwidthRate and not just the BandwidthCapacity.
-    - No longer ship INSTALL and README files -- they are useless now.
-    - Force rpmbuild to behave and honor target_cpu.
-    - Avoid warnings about machine/limits.h on Debian GNU/kFreeBSD.
-    - Start to include translated versions of the tor-doc-*.html
-      files, along with the screenshots. Still needs more work.
-    - Start sending back 512 and 451 errors if mapaddress fails,
-      rather than not sending anything back at all.
-    - When we fail to bind or listen on an incoming or outgoing
-      socket, we should close it before failing. otherwise we just
-      leak it. (thanks to weasel for finding.)
-    - Allow "getinfo dir/status/foo" to work, as long as your DirPort
-      is enabled. (This is a hack, and will be fixed in 0.1.2.x.)
-    - Make NoPublish (even though deprecated) work again.
-    - Fix a minor security flaw where a versioning auth dirserver
-      could list a recommended version many times in a row to make
-      clients more convinced that it's recommended.
-    - Fix crash bug if there are two unregistered servers running
-      with the same nickname, one of them is down, and you ask for
-      them by nickname in your EntryNodes or ExitNodes. Also, try
-      to pick the one that's running rather than an arbitrary one.
-    - Fix an infinite loop we could hit if we go offline for too long.
-    - Complain when we hit WSAENOBUFS on recv() or write() too.
-      Perhaps this will help us hunt the bug.
-    - If you're not a versioning dirserver, don't put the string
-      "client-versions \nserver-versions \n" in your network-status.
-    - Lower the minimum required number of file descriptors to 1000,
-      so we can have some overhead for Valgrind on Linux, where the
-      default ulimit -n is 1024.
-
-  o New features:
-    - Add tor.dizum.com as the fifth authoritative directory server.
-    - Add a new config option FetchUselessDescriptors, off by default,
-      for when you plan to run "exitlist" on your client and you want
-      to know about even the non-running descriptors.
-
-
-Changes in version 0.1.1.17-rc - 2006-03-28
-  o Major fixes:
-    - Clients and servers since 0.1.1.10-alpha have been expiring
-      connections whenever they are idle for 5 minutes and they *do*
-      have circuits on them. Oops. With this new version, clients will
-      discard their previous entry guard choices and avoid choosing
-      entry guards running these flawed versions.
-    - Fix memory leak when uncompressing concatenated zlib streams. This
-      was causing substantial leaks over time on Tor servers.
-    - The v1 directory was including servers as much as 48 hours old,
-      because that's how the new routerlist->routers works. Now only
-      include them if they're 20 hours old or less.
-
-  o Minor fixes:
-    - Resume building on irix64, netbsd 2.0, etc.
-    - On non-gcc compilers (e.g. solaris), use "-g -O" instead of
-      "-Wall -g -O2".
-    - Stop writing the "router.desc" file, ever. Nothing uses it anymore,
-      and it is confusing some users.
-    - Mirrors stop caching the v1 directory so often.
-    - Make the max number of old descriptors that a cache will hold
-      rise with the number of directory authorities, so we can scale.
-    - Change our win32 uname() hack to be more forgiving about what
-      win32 versions it thinks it's found.
-
-  o New features:
-    - Add lefkada.eecs.harvard.edu as a fourth authoritative directory
-      server.
-    - When the controller's *setconf commands fail, collect an error
-      message in a string and hand it back to the controller.
-    - Make the v2 dir's "Fast" flag based on relative capacity, just
-      like "Stable" is based on median uptime. Name everything in the
-      top 7/8 Fast, and only the top 1/2 gets to be a Guard.
-    - Log server fingerprint on startup, so new server operators don't
-      have to go hunting around their filesystem for it.
-    - Return a robots.txt on our dirport to discourage google indexing.
-    - Let the controller ask for GETINFO dir/status/foo so it can ask
-      directly rather than connecting to the dir port. Only works when
-      dirport is set for now.
-
-  o New config options rather than constants in the code:
-    - SocksTimeout: How long do we let a socks connection wait
-      unattached before we fail it?
-    - CircuitBuildTimeout: Cull non-open circuits that were born
-      at least this many seconds ago.
-    - CircuitIdleTimeout: Cull open clean circuits that were born
-      at least this many seconds ago.
-
-
-Changes in version 0.1.1.16-rc - 2006-03-18
-  o Bugfixes on 0.1.1.15-rc:
-    - Fix assert when the controller asks to attachstream a connect-wait
-      or resolve-wait stream.
-    - Now do address rewriting when the controller asks us to attach
-      to a particular circuit too. This will let Blossom specify
-      "moria2.exit" without having to learn what moria2's IP address is.
-    - Make the "tor --verify-config" command-line work again, so people
-      can automatically check if their torrc will parse.
-    - Authoritative dirservers no longer require an open connection from
-      a server to consider him "reachable". We need this change because
-      when we add new auth dirservers, old servers won't know not to
-      hang up on them.
-    - Let Tor build on Sun CC again.
-    - Fix an off-by-one buffer size in dirserv.c that magically never
-      hit our three authorities but broke sjmurdoch's own tor network.
-    - If we as a directory mirror don't know of any v1 directory
-      authorities, then don't try to cache any v1 directories.
-    - Stop warning about unknown servers in our family when they are
-      given as hex digests.
-    - Stop complaining as quickly to the server operator that he
-      hasn't registered his nickname/key binding.
-    - Various cleanups so we can add new V2 Auth Dirservers.
-    - Change "AllowUnverifiedNodes" to "AllowInvalidNodes", to
-      reflect the updated flags in our v2 dir protocol.
-    - Resume allowing non-printable characters for exit streams (both
-      for connecting and for resolving). Now we tolerate applications
-      that don't follow the RFCs. But continue to block malformed names
-      at the socks side.
-
-  o Bugfixes on 0.1.0.x:
-    - Fix assert bug in close_logs(): when we close and delete logs,
-      remove them all from the global "logfiles" list.
-    - Fix minor integer overflow in calculating when we expect to use up
-      our bandwidth allocation before hibernating.
-    - Fix a couple of bugs in OpenSSL detection. Also, deal better when
-      there are multiple SSLs installed with different versions.
-    - When we try to be a server and Address is not explicitly set and
-      our hostname resolves to a private IP address, try to use an
-      interface address if it has a public address. Now Windows machines
-      that think of themselves as localhost can work by default.
-
-  o New features:
-    - Let the controller ask for GETINFO dir/server/foo so it can ask
-      directly rather than connecting to the dir port.
-    - Let the controller tell us about certain router descriptors
-      that it doesn't want Tor to use in circuits. Implement
-      SETROUTERPURPOSE and modify +POSTDESCRIPTOR to do this.
-    - New config option SafeSocks to reject all application connections
-      using unsafe socks protocols. Defaults to off.
-
-
-Changes in version 0.1.1.15-rc - 2006-03-11
-  o Bugfixes and cleanups:
-    - When we're printing strings from the network, don't try to print
-      non-printable characters. This protects us against shell escape
-      sequence exploits, and also against attacks to fool humans into
-      misreading their logs.
-    - Fix a bug where Tor would fail to establish any connections if you
-      left it off for 24 hours and then started it: we were happy with
-      the obsolete network statuses, but they all referred to router
-      descriptors that were too old to fetch, so we ended up with no
-      valid router descriptors.
-    - Fix a seg fault in the controller's "getinfo orconn-status" command
-      while listing status on incoming handshaking connections. Introduce
-      a status name "NEW" for these connections.
-    - If we get a linelist or linelist_s config option from the torrc
-      (e.g. ExitPolicy) and it has no value, warn and skip rather than
-      silently resetting it to its default.
-    - Don't abandon entry guards until they've been down or gone for
-      a whole month.
-    - Cleaner and quieter log messages.
-
-  o New features:
-    - New controller signal NEWNYM that makes new application requests
-      use clean circuits.
-    - Add a new circuit purpose 'controller' to let the controller ask
-      for a circuit that Tor won't try to use. Extend the EXTENDCIRCUIT
-      controller command to let you specify the purpose if you're starting
-      a new circuit.  Add a new SETCIRCUITPURPOSE controller command to
-      let you change a circuit's purpose after it's been created.
-    - Accept "private:*" in routerdesc exit policies; not generated yet
-      because older Tors do not understand it.
-    - Add BSD-style contributed startup script "rc.subr" from Peter
-      Thoenen.
-
-
-Changes in version 0.1.1.14-alpha - 2006-02-20
-  o Bugfixes on 0.1.1.x:
-    - Don't die if we ask for a stdout or stderr log (even implicitly)
-      and we're set to RunAsDaemon -- just warn.
-    - We still had a few bugs in the OR connection rotation code that
-      caused directory servers to slowly aggregate connections to other
-      fast Tor servers. This time for sure!
-    - Make log entries on Win32 include the name of the function again.
-    - We were treating a pair of exit policies if they were equal even
-      if one said accept and the other said reject -- causing us to
-      not always publish a new descriptor since we thought nothing
-      had changed.
-    - Retry pending server downloads as well as pending networkstatus
-      downloads when we unexpectedly get a socks request.
-    - We were ignoring the IS_FAST flag in the directory status,
-      meaning we were willing to pick trivial-bandwidth nodes for "fast"
-      connections.
-    - If the controller's SAVECONF command fails (e.g. due to file
-      permissions), let the controller know that it failed.
-
-  o Features:
-    - If we're trying to be a Tor server and running Windows 95/98/ME
-      as a server, explain that we'll likely crash.
-    - When we're a server, a client asks for an old-style directory,
-      and our write bucket is empty, don't give it to him. This way
-      small servers can continue to serve the directory *sometimes*,
-      without getting overloaded.
-    - Compress exit policies even more -- look for duplicate lines
-      and remove them.
-    - Clients now honor the "guard" flag in the router status when
-      picking entry guards, rather than looking at is_fast or is_stable.
-    - Retain unrecognized lines in $DATADIR/state file, so that we can
-      be forward-compatible.
-    - Generate 18.0.0.0/8 address policy format in descs when we can;
-      warn when the mask is not reducible to a bit-prefix.
-    - Let the user set ControlListenAddress in the torrc.  This can be
-      dangerous, but there are some cases (like a secured LAN) where it
-      makes sense.
-    - Split ReachableAddresses into ReachableDirAddresses and
-      ReachableORAddresses, so we can restrict Dir conns to port 80
-      and OR conns to port 443.
-    - Now we can target arch and OS in rpm builds (contributed by
-      Phobos). Also make the resulting dist-rpm filename match the
-      target arch.
-    - New config options to help controllers: FetchServerDescriptors
-      and FetchHidServDescriptors for whether to fetch server
-      info and hidserv info or let the controller do it, and
-      PublishServerDescriptor and PublishHidServDescriptors.
-    - Also let the controller set the __AllDirActionsPrivate config
-      option if you want all directory fetches/publishes to happen via
-      Tor (it assumes your controller bootstraps your circuits).
-
-
-Changes in version 0.1.1.13-alpha - 2006-02-09
-  o Crashes in 0.1.1.x:
-    - When you tried to setconf ORPort via the controller, Tor would
-      crash. So people using TorCP to become a server were sad.
-    - Solve (I hope) the stack-smashing bug that we were seeing on fast
-      servers. The problem appears to be something do with OpenSSL's
-      random number generation, or how we call it, or something. Let me
-      know if the crashes continue.
-    - Turn crypto hardware acceleration off by default, until we find
-      somebody smart who can test it for us. (It appears to produce
-      seg faults in at least some cases.)
-    - Fix a rare assert error when we've tried all intro points for
-      a hidden service and we try fetching the service descriptor again:
-      "Assertion conn->state != AP_CONN_STATE_RENDDESC_WAIT failed"
-
-  o Major fixes:
-    - Fix a major load balance bug: we were round-robining in 16 KB
-      chunks, and servers with bandwidthrate of 20 KB, while downloading
-      a 600 KB directory, would starve their other connections. Now we
-      try to be a bit more fair.
-    - Dir authorities and mirrors were never expiring the newest
-      descriptor for each server, causing memory and directory bloat.
-    - Fix memory-bloating and connection-bloating bug on servers: We
-      were never closing any connection that had ever had a circuit on
-      it, because we were checking conn->n_circuits == 0, yet we had a
-      bug that let it go negative.
-    - Make Tor work using squid as your http proxy again -- squid
-      returns an error if you ask for a URL that's too long, and it uses
-      a really generic error message. Plus, many people are behind a
-      transparent squid so they don't even realize it.
-    - On platforms that don't have getrlimit (like Windows), we were
-      artificially constraining ourselves to a max of 1024
-      connections. Now just assume that we can handle as many as 15000
-      connections. Hopefully this won't cause other problems.
-    - Add a new config option ExitPolicyRejectPrivate which defaults to
-      1. This means all exit policies will begin with rejecting private
-      addresses, unless the server operator explicitly turns it off.
-
-  o Major features:
-    - Clients no longer download descriptors for non-running descriptors.
-    - Before we add new directory authorities, we should make it
-      clear that only v1 authorities should receive/publish hidden
-      service descriptors.
-
-  o Minor features:
-    - As soon as we've fetched some more directory info, immediately
-      try to download more server descriptors. This way we don't have
-      a 10 second pause during initial bootstrapping.
-    - Remove even more loud log messages that the server operator can't
-      do anything about.
-    - When we're running an obsolete or un-recommended version, make
-      the log message more clear about what the problem is and what
-      versions *are* still recommended.
-    - Provide a more useful warn message when our onion queue gets full:
-      the CPU is too slow or the exit policy is too liberal.
-    - Don't warn when we receive a 503 from a dirserver/cache -- this
-      will pave the way for them being able to refuse if they're busy.
-    - When we fail to bind a listener, try to provide a more useful
-      log message: e.g., "Is Tor already running?"
-    - Adjust tor-spec to parameterize cell and key lengths. Now Ian
-      Goldberg can prove things about our handshake protocol more
-      easily.
-    - MaxConn has been obsolete for a while now. Document the ConnLimit
-      config option, which is a *minimum* number of file descriptors
-      that must be available else Tor refuses to start.
-    - Apply Matt Ghali's --with-syslog-facility patch to ./configure
-      if you log to syslog and want something other than LOG_DAEMON.
-    - Make dirservers generate a separate "guard" flag to mean,
-      "would make a good entry guard". Make clients parse it and vote
-      on it. Not used by clients yet.
-    - Implement --with-libevent-dir option to ./configure. Also, improve
-      search techniques to find libevent, and use those for openssl too.
-    - Bump the default bandwidthrate to 3 MB, and burst to 6 MB
-    - Only start testing reachability once we've established a
-      circuit. This will make startup on dirservers less noisy.
-    - Don't try to upload hidden service descriptors until we have
-      established a circuit.
-    - Fix the controller's "attachstream 0" command to treat conn like
-      it just connected, doing address remapping, handling .exit and
-      .onion idioms, and so on. Now we're more uniform in making sure
-      that the controller hears about new and closing connections.
-
-
-Changes in version 0.1.1.12-alpha - 2006-01-11
-  o Bugfixes on 0.1.1.x:
-    - The fix to close duplicate server connections was closing all
-      Tor client connections if they didn't establish a circuit
-      quickly enough. Oops.
-    - Fix minor memory issue (double-free) that happened on exit.
-
-  o Bugfixes on 0.1.0.x:
-    - Tor didn't warn when it failed to open a log file.
-
-
-Changes in version 0.1.1.11-alpha - 2006-01-10
-  o Crashes in 0.1.1.x:
-    - Include all the assert/crash fixes from 0.1.0.16.
-    - If you start Tor and then quit very quickly, there were some
-      races that tried to free things that weren't allocated yet.
-    - Fix a rare memory stomp if you're running hidden services.
-    - Fix segfault when specifying DirServer in config without nickname.
-    - Fix a seg fault when you finish connecting to a server but at
-      that moment you dump his server descriptor.
-    - Extendcircuit and Attachstream controller commands would
-      assert/crash if you don't give them enough arguments.
-    - Fix an assert error when we're out of space in the connection_list
-      and we try to post a hidden service descriptor (reported by weasel).
-    - If you specify a relative torrc path and you set RunAsDaemon in
-      your torrc, then it chdir()'s to the new directory. If you HUP,
-      it tries to load the new torrc location, fails, and exits.
-      The fix: no longer allow a relative path to torrc using -f.
-
-  o Major features:
-    - Implement "entry guards": automatically choose a handful of entry
-      nodes and stick with them for all circuits. Only pick new guards
-      when the ones you have are unsuitable, and if the old guards
-      become suitable again, switch back. This will increase security
-      dramatically against certain end-point attacks. The EntryNodes
-      config option now provides some hints about which entry guards you
-      want to use most; and StrictEntryNodes means to only use those.
-      (CVE-2006-0414)
-    - New directory logic: download by descriptor digest, not by
-      fingerprint. Caches try to download all listed digests from
-      authorities; clients try to download "best" digests from caches.
-      This avoids partitioning and isolating attacks better.
-    - Make the "stable" router flag in network-status be the median of
-      the uptimes of running valid servers, and make clients pay
-      attention to the network-status flags. Thus the cutoff adapts
-      to the stability of the network as a whole, making IRC, IM, etc
-      connections more reliable.
-
-  o Major fixes:
-    - Tor servers with dynamic IP addresses were needing to wait 18
-      hours before they could start doing reachability testing using
-      the new IP address and ports. This is because they were using
-      the internal descriptor to learn what to test, yet they were only
-      rebuilding the descriptor once they decided they were reachable.
-    - Tor 0.1.1.9 and 0.1.1.10 had a serious bug that caused clients
-      to download certain server descriptors, throw them away, and then
-      fetch them again after 30 minutes. Now mirrors throw away these
-      server descriptors so clients can't get them.
-    - We were leaving duplicate connections to other ORs open for a week,
-      rather than closing them once we detect a duplicate. This only
-      really affected authdirservers, but it affected them a lot.
-    - Spread the authdirservers' reachability testing over the entire
-      testing interval, so we don't try to do 500 TLS's at once every
-      20 minutes.
-
-  o Minor fixes:
-    - If the network is down, and we try to connect to a conn because
-      we have a circuit in mind, and we timeout (30 seconds) because the
-      network never answers, we were expiring the circuit, but we weren't
-      obsoleting the connection or telling the entry_guards functions.
-    - Some Tor servers process billions of cells per day. These statistics
-      need to be uint64_t's.
-    - Check for integer overflows in more places, when adding elements
-      to smartlists. This could possibly prevent a buffer overflow
-      on malicious huge inputs. I don't see any, but I haven't looked
-      carefully.
-    - ReachableAddresses kept growing new "reject *:*" lines on every
-      setconf/reload.
-    - When you "setconf log" via the controller, it should remove all
-      logs. We were automatically adding back in a "log notice stdout".
-    - Newly bootstrapped Tor networks couldn't establish hidden service
-      circuits until they had nodes with high uptime. Be more tolerant.
-    - We were marking servers down when they could not answer every piece
-      of the directory request we sent them. This was far too harsh.
-    - Fix the torify (tsocks) config file to not use Tor for localhost
-      connections.
-    - Directory authorities now go to the proper authority when asking for
-      a networkstatus, even when they want a compressed one.
-    - Fix a harmless bug that was causing Tor servers to log
-      "Got an end because of misc error, but we're not an AP. Closing."
-    - Authorities were treating their own descriptor changes as cosmetic,
-      meaning the descriptor available in the network-status and the
-      descriptor that clients downloaded were different.
-    - The OS X installer was adding a symlink for tor_resolve but
-      the binary was called tor-resolve (reported by Thomas Hardly).
-    - Workaround a problem with some http proxies where they refuse GET
-      requests that specify "Content-Length: 0" (reported by Adrian).
-    - Fix wrong log message when you add a "HiddenServiceNodes" config
-      line without any HiddenServiceDir line (reported by Chris Thomas).
-
-  o Minor features:
-    - Write the TorVersion into the state file so we have a prayer of
-      keeping forward and backward compatibility.
-    - Revive the FascistFirewall config option rather than eliminating it:
-      now it's a synonym for ReachableAddresses *:80,*:443.
-    - Clients choose directory servers from the network status lists,
-      not from their internal list of router descriptors. Now they can
-      go to caches directly rather than needing to go to authorities
-      to bootstrap.
-    - Directory authorities ignore router descriptors that have only
-      cosmetic differences: do this for 0.1.0.x servers now too.
-    - Add a new flag to network-status indicating whether the server
-      can answer v2 directory requests too.
-    - Authdirs now stop whining so loudly about bad descriptors that
-      they fetch from other dirservers. So when there's a log complaint,
-      it's for sure from a freshly uploaded descriptor.
-    - Reduce memory requirements in our structs by changing the order
-      of fields.
-    - There used to be two ways to specify your listening ports in a
-      server descriptor: on the "router" line and with a separate "ports"
-      line. Remove support for the "ports" line.
-    - New config option "AuthDirRejectUnlisted" for auth dirservers as
-      a panic button: if we get flooded with unusable servers we can
-      revert to only listing servers in the approved-routers file.
-    - Auth dir servers can now mark a fingerprint as "!reject" or
-      "!invalid" in the approved-routers file (as its nickname), to
-      refuse descriptors outright or include them but marked as invalid.
-    - Servers store bandwidth history across restarts/crashes.
-    - Add reasons to DESTROY and RELAY_TRUNCATED cells, so clients can
-      get a better idea of why their circuits failed. Not used yet.
-    - Directory mirrors now cache up to 16 unrecognized network-status
-      docs. Now we can add new authdirservers and they'll be cached too.
-    - When picking a random directory, prefer non-authorities if any
-      are known.
-    - New controller option "getinfo desc/all-recent" to fetch the
-      latest server descriptor for every router that Tor knows about.
-
-
-Changes in version 0.1.1.10-alpha - 2005-12-11
-  o Correctness bugfixes on 0.1.0.x:
-    - On Windows, build with a libevent patch from "I-M Weasel" to avoid
-      corrupting the heap, losing FDs, or crashing when we need to resize
-      the fd_sets. (This affects the Win32 binaries, not Tor's sources.)
-    - Stop doing the complex voodoo overkill checking for insecure
-      Diffie-Hellman keys. Just check if it's in [2,p-2] and be happy.
-    - When we were closing connections, there was a rare case that
-      stomped on memory, triggering seg faults and asserts.
-    - We were neglecting to unlink marked circuits from soon-to-close OR
-      connections, which caused some rare scribbling on freed memory.
-    - When we're deciding whether a stream has enough circuits around
-      that can handle it, count the freshly dirty ones and not the ones
-      that are so dirty they won't be able to handle it.
-    - Recover better from TCP connections to Tor servers that are
-      broken but don't tell you (it happens!); and rotate TLS
-      connections once a week.
-    - When we're expiring old circuits, we had a logic error that caused
-      us to close new rendezvous circuits rather than old ones.
-    - Fix a scary-looking but apparently harmless bug where circuits
-      would sometimes start out in state CIRCUIT_STATE_OR_WAIT at
-      servers, and never switch to state CIRCUIT_STATE_OPEN.
-    - When building with -static or on Solaris, we sometimes needed to
-      build with -ldl.
-    - Give a useful message when people run Tor as the wrong user,
-      rather than telling them to start chowning random directories.
-    - We were failing to inform the controller about new .onion streams.
-
-  o Security bugfixes on 0.1.0.x:
-    - Refuse server descriptors if the fingerprint line doesn't match
-      the included identity key. Tor doesn't care, but other apps (and
-      humans) might actually be trusting the fingerprint line.
-    - We used to kill the circuit when we receive a relay command we
-      don't recognize. Now we just drop it.
-    - Start obeying our firewall options more rigorously:
-      . If we can't get to a dirserver directly, try going via Tor.
-      . Don't ever try to connect (as a client) to a place our
-        firewall options forbid.
-      . If we specify a proxy and also firewall options, obey the
-        firewall options even when we're using the proxy: some proxies
-        can only proxy to certain destinations.
-    - Fix a bug found by Lasse Overlier: when we were making internal
-      circuits (intended to be cannibalized later for rendezvous and
-      introduction circuits), we were picking them so that they had
-      useful exit nodes. There was no need for this, and it actually
-      aids some statistical attacks.
-    - Start treating internal circuits and exit circuits separately.
-      It's important to keep them separate because internal circuits
-      have their last hops picked like middle hops, rather than like
-      exit hops. So exiting on them will break the user's expectations.
-
-  o Bugfixes on 0.1.1.x:
-    - Take out the mis-feature where we tried to detect IP address
-      flapping for people with DynDNS, and chose not to upload a new
-      server descriptor sometimes.
-    - Try to be compatible with OpenSSL 0.9.6 again.
-    - Log fix: when the controller is logging about .onion addresses,
-      sometimes it didn't include the ".onion" part of the address.
-    - Don't try to modify options->DirServers internally -- if the
-      user didn't specify any, just add the default ones directly to
-      the trusted dirserver list. This fixes a bug where people running
-      controllers would use SETCONF on some totally unrelated config
-      option, and Tor would start yelling at them about changing their
-      DirServer lines.
-    - Let the controller's redirectstream command specify a port, in
-      case the controller wants to change that too.
-    - When we requested a pile of server descriptors, we sometimes
-      accidentally launched a duplicate request for the first one.
-    - Bugfix for trackhostexits: write down the fingerprint of the
-      chosen exit, not its nickname, because the chosen exit might not
-      be verified.
-    - When parsing foo.exit, if foo is unknown, and we are leaving
-      circuits unattached, set the chosen_exit field and leave the
-      address empty. This matters because controllers got confused
-      otherwise.
-    - Directory authorities no longer try to download server
-      descriptors that they know they will reject.
-
-  o Features and updates:
-    - Replace balanced trees with hash tables: this should make stuff
-      significantly faster.
-    - Resume using the AES counter-mode implementation that we ship,
-      rather than OpenSSL's. Ours is significantly faster.
-    - Many other CPU and memory improvements.
-    - Add a new config option FastFirstHopPK (on by default) so clients
-      do a trivial crypto handshake for their first hop, since TLS has
-      already taken care of confidentiality and authentication.
-    - Add a new config option TestSocks so people can see if their
-      applications are using socks4, socks4a, socks5-with-ip, or
-      socks5-with-hostname. This way they don't have to keep mucking
-      with tcpdump and wondering if something got cached somewhere.
-    - Warn when listening on a public address for socks. I suspect a
-      lot of people are setting themselves up as open socks proxies,
-      and they have no idea that jerks on the Internet are using them,
-      since they simply proxy the traffic into the Tor network.
-    - Add "private:*" as an alias in configuration for policies. Now
-      you can simplify your exit policy rather than needing to list
-      every single internal or nonroutable network space.
-    - Add a new controller event type that allows controllers to get
-      all server descriptors that were uploaded to a router in its role
-      as authoritative dirserver.
-    - Start shipping socks-extensions.txt, tor-doc-unix.html,
-      tor-doc-server.html, and stylesheet.css in the tarball.
-    - Stop shipping tor-doc.html in the tarball.
-
-
-Changes in version 0.1.1.9-alpha - 2005-11-15
-  o Usability improvements:
-    - Start calling it FooListenAddress rather than FooBindAddress,
-      since few of our users know what it means to bind an address
-      or port.
-    - Reduce clutter in server logs. We're going to try to make
-      them actually usable now. New config option ProtocolWarnings that
-      lets you hear about how _other Tors_ are breaking the protocol. Off
-      by default.
-    - Divide log messages into logging domains. Once we put some sort
-      of interface on this, it will let people looking at more verbose
-      log levels specify the topics they want to hear more about.
-    - Make directory servers return better http 404 error messages
-      instead of a generic "Servers unavailable".
-    - Check for even more Windows version flags when writing the platform
-      string in server descriptors, and note any we don't recognize.
-    - Clean up more of the OpenSSL memory when exiting, so we can detect
-      memory leaks better.
-    - Make directory authorities be non-versioning, non-naming by
-      default. Now we can add new directory servers without requiring
-      their operators to pay close attention.
-    - When logging via syslog, include the pid whenever we provide
-      a log entry. Suggested by Todd Fries.
-
-  o Performance improvements:
-    - Directory servers now silently throw away new descriptors that
-      haven't changed much if the timestamps are similar. We do this to
-      tolerate older Tor servers that upload a new descriptor every 15
-      minutes. (It seemed like a good idea at the time.)
-    - Inline bottleneck smartlist functions; use fast versions by default.
-    - Add a "Map from digest to void*" abstraction digestmap_t so we
-      can do less hex encoding/decoding. Use it in router_get_by_digest()
-      to resolve a performance bottleneck.
-    - Allow tor_gzip_uncompress to extract as much as possible from
-      truncated compressed data. Try to extract as many
-      descriptors as possible from truncated http responses (when
-      DIR_PURPOSE_FETCH_ROUTERDESC).
-    - Make circ->onionskin a pointer, not a static array. moria2 was using
-      125000 circuit_t's after it had been up for a few weeks, which
-      translates to 20+ megs of wasted space.
-    - The private half of our EDH handshake keys are now chosen out
-      of 320 bits, not 1024 bits. (Suggested by Ian Goldberg.)
-
-  o Security improvements:
-    - Start making directory caches retain old routerinfos, so soon
-      clients can start asking by digest of descriptor rather than by
-      fingerprint of server.
-    - Add half our entropy from RAND_poll in OpenSSL.  This knows how
-      to use egd (if present), openbsd weirdness (if present), vms/os2
-      weirdness (if we ever port there), and more in the future.
-
-  o Bugfixes on 0.1.0.x:
-    - Do round-robin writes of at most 16 kB per write. This might be
-      more fair on loaded Tor servers, and it might resolve our Windows
-      crash bug. It might also slow things down.
-    - Our TLS handshakes were generating a single public/private
-      keypair for the TLS context, rather than making a new one for
-      each new connections. Oops. (But we were still rotating them
-      periodically, so it's not so bad.)
-    - When we were cannibalizing a circuit with a particular exit
-      node in mind, we weren't checking to see if that exit node was
-      already present earlier in the circuit. Oops.
-    - When a Tor server's IP changes (e.g. from a dyndns address),
-      upload a new descriptor so clients will learn too.
-    - Really busy servers were keeping enough circuits open on stable
-      connections that they were wrapping around the circuit_id
-      space. (It's only two bytes.) This exposed a bug where we would
-      feel free to reuse a circuit_id even if it still exists but has
-      been marked for close. Try to fix this bug. Some bug remains.
-    - If we would close a stream early (e.g. it asks for a .exit that
-      we know would refuse it) but the LeaveStreamsUnattached config
-      option is set by the controller, then don't close it.
-
-  o Bugfixes on 0.1.1.8-alpha:
-    - Fix a big pile of memory leaks, some of them serious.
-    - Do not try to download a routerdesc if we would immediately reject
-      it as obsolete.
-    - Resume inserting a newline between all router descriptors when
-      generating (old style) signed directories, since our spec says
-      we do.
-    - When providing content-type application/octet-stream for
-      server descriptors using .z, we were leaving out the
-      content-encoding header. Oops. (Everything tolerated this just
-      fine, but that doesn't mean we need to be part of the problem.)
-    - Fix a potential seg fault in getconf and getinfo using version 1
-      of the controller protocol.
-    - Avoid crash: do not check whether DirPort is reachable when we
-      are suppressing it because of hibernation.
-    - Make --hash-password not crash on exit.
-
-
-Changes in version 0.1.1.8-alpha - 2005-10-07
-  o New features (major):
-    - Clients don't download or use the directory anymore. Now they
-      download and use network-statuses from the trusted dirservers,
-      and fetch individual server descriptors as needed from mirrors.
-      See dir-spec.txt for all the gory details.
-    - Be more conservative about whether to advertise our DirPort.
-      The main change is to not advertise if we're running at capacity
-      and either a) we could hibernate or b) our capacity is low and
-      we're using a default DirPort.
-    - Use OpenSSL's AES when OpenSSL has version 0.9.7 or later.
-
-  o New features (minor):
-    - Try to be smart about when to retry network-status and
-      server-descriptor fetches. Still needs some tuning.
-    - Stop parsing, storing, or using running-routers output (but
-      mirrors still cache and serve it).
-    - Consider a threshold of versioning dirservers (dirservers who have
-      an opinion about which Tor versions are still recommended) before
-      deciding whether to warn the user that he's obsolete.
-    - Dirservers can now reject/invalidate by key and IP, with the
-      config options "AuthDirInvalid" and "AuthDirReject". This is
-      useful since currently we automatically list servers as running
-      and usable even if we know they're jerks.
-    - Provide dire warnings to any users who set DirServer; move it out
-      of torrc.sample and into torrc.complete.
-    - Add MyFamily to torrc.sample in the server section.
-    - Add nicknames to the DirServer line, so we can refer to them
-      without requiring all our users to memorize their IP addresses.
-    - When we get an EOF or a timeout on a directory connection, note
-      how many bytes of serverdesc we are dropping. This will help
-      us determine whether it is smart to parse incomplete serverdesc
-      responses.
-    - Add a new function to "change pseudonyms" -- that is, to stop
-      using any currently-dirty circuits for new streams, so we don't
-      link new actions to old actions. Currently it's only called on
-      HUP (or SIGNAL RELOAD).
-    - On sighup, if UseHelperNodes changed to 1, use new circuits.
-    - Start using RAND_bytes rather than RAND_pseudo_bytes from
-      OpenSSL. Also, reseed our entropy every hour, not just at
-      startup. And entropy in 512-bit chunks, not 160-bit chunks.
-
-  o Fixes on 0.1.1.7-alpha:
-    - Nobody ever implemented EVENT_ADDRMAP for control protocol
-      version 0, so don't let version 0 controllers ask for it.
-    - If you requested something with too many newlines via the
-      v1 controller protocol, you could crash tor.
-    - Fix a number of memory leaks, including some pretty serious ones.
-    - Re-enable DirPort testing again, so Tor servers will be willing
-      to advertise their DirPort if it's reachable.
-    - On TLS handshake, only check the other router's nickname against
-      its expected nickname if is_named is set.
-
-  o Fixes forward-ported from 0.1.0.15:
-    - Don't crash when we don't have any spare file descriptors and we
-      try to spawn a dns or cpu worker.
-    - Make the numbers in read-history and write-history into uint64s,
-      so they don't overflow and publish negatives in the descriptor.
-
-  o Fixes on 0.1.0.x:
-    - For the OS X package's modified privoxy config file, comment
-      out the "logfile" line so we don't log everything passed
-      through privoxy.
-    - We were whining about using socks4 or socks5-with-local-lookup
-      even when it's an IP in the "virtual" range we designed exactly
-      for this case.
-    - We were leaking some memory every time the client changes IPs.
-    - Never call free() on tor_malloc()d memory. This will help us
-      use dmalloc to detect memory leaks.
-    - Check for named servers when looking them up by nickname;
-      warn when we'recalling a non-named server by its nickname;
-      don't warn twice about the same name.
-    - Try to list MyFamily elements by key, not by nickname, and warn
-      if we've not heard of the server.
-    - Make windows platform detection (uname equivalent) smarter.
-    - It turns out sparc64 doesn't like unaligned access either.
-
-
-Changes in version 0.1.1.7-alpha - 2005-09-14
-  o Fixes on 0.1.1.6-alpha:
-    - Exit servers were crashing when people asked them to make a
-      connection to an address not in their exit policy.
-    - Looking up a non-existent stream for a v1 control connection would
-      cause a segfault.
-    - Fix a seg fault if we ask a dirserver for a descriptor by
-      fingerprint but he doesn't know about him.
-    - SETCONF was appending items to linelists, not clearing them.
-    - SETCONF SocksBindAddress killed Tor if it fails to bind. Now back
-      out and refuse the setconf if it would fail.
-    - Downgrade the dirserver log messages when whining about
-      unreachability.
-
-  o New features:
-    - Add Peter Palfrader's check-tor script to tor/contrib/
-      It lets you easily check whether a given server (referenced by
-      nickname) is reachable by you.
-    - Numerous changes to move towards client-side v2 directories. Not
-      enabled yet.
-
-  o Fixes on 0.1.0.x:
-    - If the user gave tor an odd number of command-line arguments,
-      we were silently ignoring the last one. Now we complain and fail.
-      [This wins the oldest-bug prize -- this bug has been present since
-       November 2002, as released in Tor 0.0.0.]
-    - Do not use unaligned memory access on alpha, mips, or mipsel.
-      It *works*, but is very slow, so we treat them as if it doesn't.
-    - Retry directory requests if we fail to get an answer we like
-      from a given dirserver (we were retrying before, but only if
-      we fail to connect).
-    - When writing the RecommendedVersions line, sort them first.
-    - When the client asked for a rendezvous port that the hidden
-      service didn't want to provide, we were sending an IP address
-      back along with the end cell. Fortunately, it was zero. But stop
-      that anyway.
-    - Correct "your server is reachable" log entries to indicate that
-      it was self-testing that told us so.
-
-
-Changes in version 0.1.1.6-alpha - 2005-09-09
-  o Fixes on 0.1.1.5-alpha:
-    - We broke fascistfirewall in 0.1.1.5-alpha. Oops.
-    - Fix segfault in unit tests in 0.1.1.5-alpha. Oops.
-    - Fix bug with tor_memmem finding a match at the end of the string.
-    - Make unit tests run without segfaulting.
-    - Resolve some solaris x86 compile warnings.
-    - Handle duplicate lines in approved-routers files without warning.
-    - Fix bug where as soon as a server refused any requests due to his
-      exit policy (e.g. when we ask for localhost and he tells us that's
-      127.0.0.1 and he won't do it), we decided he wasn't obeying his
-      exit policy and stopped using him for any exits.
-    - Only do openssl hardware accelerator stuff if openssl version is
-      at least 0.9.7.
-
-  o New controller features/fixes:
-    - Add a "RESETCONF" command so you can set config options like
-      AllowUnverifiedNodes and LongLivedPorts to "". Also, if you give
-      a config option in the torrc with no value, then it clears it
-      entirely (rather than setting it to its default).
-    - Add a "GETINFO config-file" to tell us where torrc is.
-    - Avoid sending blank lines when GETINFO replies should be empty.
-    - Add a QUIT command for the controller (for using it manually).
-    - Fix a bug in SAVECONF that was adding default dirservers and
-      other redundant entries to the torrc file.
-
-  o Start on the new directory design:
-    - Generate, publish, cache, serve new network-status format.
-    - Publish individual descriptors (by fingerprint, by "all", and by
-      "tell me yours").
-    - Publish client and server recommended versions separately.
-    - Allow tor_gzip_uncompress() to handle multiple concatenated
-      compressed strings. Serve compressed groups of router
-      descriptors. The compression logic here could be more
-      memory-efficient.
-    - Distinguish v1 authorities (all currently trusted directories)
-      from v2 authorities (all trusted directories).
-    - Change DirServers config line to note which dirs are v1 authorities.
-    - Add configuration option "V1AuthoritativeDirectory 1" which
-      moria1, moria2, and tor26 should set.
-    - Remove option when getting directory cache to see whether they
-      support running-routers; they all do now. Replace it with one
-      to see whether caches support v2 stuff.
-
-  o New features:
-    - Dirservers now do their own external reachability testing of each
-      Tor server, and only list them as running if they've been found to
-      be reachable. We also send back warnings to the server's logs if
-      it uploads a descriptor that we already believe is unreachable.
-    - Implement exit enclaves: if we know an IP address for the
-      destination, and there's a running Tor server at that address
-      which allows exit to the destination, then extend the circuit to
-      that exit first. This provides end-to-end encryption and end-to-end
-      authentication. Also, if the user wants a .exit address or enclave,
-      use 4 hops rather than 3, and cannibalize a general circ for it
-      if you can.
-    - Permit transitioning from ORPort=0 to ORPort!=0, and back, from the
-      controller. Also, rotate dns and cpu workers if the controller
-      changes options that will affect them; and initialize the dns
-      worker cache tree whether or not we start out as a server.
-    - Only upload a new server descriptor when options change, 18
-      hours have passed, uptime is reset, or bandwidth changes a lot.
-    - Check [X-]Forwarded-For headers in HTTP requests when generating
-      log messages. This lets people run dirservers (and caches) behind
-      Apache but still know which IP addresses are causing warnings.
-
-  o Config option changes:
-    - Replace (Fascist)Firewall* config options with a new
-      ReachableAddresses option that understands address policies.
-      For example, "ReachableAddresses *:80,*:443"
-    - Get rid of IgnoreVersion undocumented config option, and make us
-      only warn, never exit, when we're running an obsolete version.
-    - Make MonthlyAccountingStart config option truly obsolete now.
-
-  o Fixes on 0.1.0.x:
-    - Reject ports 465 and 587 in the default exit policy, since
-      people have started using them for spam too.
-    - It turns out we couldn't bootstrap a network since we added
-      reachability detection in 0.1.0.1-rc. Good thing the Tor network
-      has never gone down. Add an AssumeReachable config option to let
-      servers and dirservers bootstrap. When we're trying to build a
-      high-uptime or high-bandwidth circuit but there aren't enough
-      suitable servers, try being less picky rather than simply failing.
-    - Our logic to decide if the OR we connected to was the right guy
-      was brittle and maybe open to a mitm for unverified routers.
-    - We weren't cannibalizing circuits correctly for
-      CIRCUIT_PURPOSE_C_ESTABLISH_REND and
-      CIRCUIT_PURPOSE_S_ESTABLISH_INTRO, so we were being forced to
-      build those from scratch. This should make hidden services faster.
-    - Predict required circuits better, with an eye toward making hidden
-      services faster on the service end.
-    - Retry streams if the exit node sends back a 'misc' failure. This
-      should result in fewer random failures. Also, after failing
-      from resolve failed or misc, reset the num failures, so we give
-      it a fair shake next time we try.
-    - Clean up the rendezvous warn log msgs, and downgrade some to info.
-    - Reduce severity on logs about dns worker spawning and culling.
-    - When we're shutting down and we do something like try to post a
-      server descriptor or rendezvous descriptor, don't complain that
-      we seem to be unreachable. Of course we are, we're shutting down.
-    - Add TTLs to RESOLVED, CONNECTED, and END_REASON_EXITPOLICY cells.
-      We don't use them yet, but maybe one day our DNS resolver will be
-      able to discover them.
-    - Make ContactInfo mandatory for authoritative directory servers.
-    - Require server descriptors to list IPv4 addresses -- hostnames
-      are no longer allowed. This also fixes some potential security
-      problems with people providing hostnames as their address and then
-      preferentially resolving them to partition users.
-    - Change log line for unreachability to explicitly suggest /etc/hosts
-      as the culprit. Also make it clearer what IP address and ports we're
-      testing for reachability.
-    - Put quotes around user-supplied strings when logging so users are
-      more likely to realize if they add bad characters (like quotes)
-      to the torrc.
-    - Let auth dir servers start without specifying an Address config
-      option.
-    - Make unit tests (and other invocations that aren't the real Tor)
-      run without launching listeners, creating subdirectories, and so on.

-Changes in version 0.1.1.5-alpha - 2005-08-08
-  o Bugfixes included in 0.1.0.14.
-
-  o Bugfixes on 0.1.0.x:
-    - If you write "HiddenServicePort 6667 127.0.0.1 6668" in your
-      torrc rather than "HiddenServicePort 6667 127.0.0.1:6668",
-      it would silently using ignore the 6668.
-
-
-Changes in version 0.1.1.4-alpha - 2005-08-04
-  o Bugfixes included in 0.1.0.13.
-
-  o Features:
-    - Improve tor_gettimeofday() granularity on windows.
-    - Make clients regenerate their keys when their IP address changes.
-    - Implement some more GETINFO goodness: expose helper nodes, config
-      options, getinfo keys.
-
-
-Changes in version 0.1.1.3-alpha - 2005-07-25
-  o Bugfixes on 0.1.1.2-alpha:
-    - Fix a bug in handling the controller's "post descriptor"
-      function.
-    - Fix several bugs in handling the controller's "extend circuit"
-      function.
-    - Fix a bug in handling the controller's "stream status" event.
-    - Fix an assert failure if we have a controller listening for
-      circuit events and we go offline.
-    - Re-allow hidden service descriptors to publish 0 intro points.
-    - Fix a crash when generating your hidden service descriptor if
-      you don't have enough intro points already.
-
-  o New features on 0.1.1.2-alpha:
-    - New controller function "getinfo accounting", to ask how
-      many bytes we've used in this time period.
-    - Experimental support for helper nodes: a lot of the risk from
-      a small static adversary comes because users pick new random
-      nodes every time they rebuild a circuit. Now users will try to
-      stick to the same small set of entry nodes if they can. Not
-      enabled by default yet.
-
-  o Bugfixes on 0.1.0.12:
-    - If you're an auth dir server, always publish your dirport,
-      even if you haven't yet found yourself to be reachable.
-    - Fix a size_t underflow in smartlist_join_strings2() that made
-      it do bad things when you hand it an empty smartlist.
-
-
-Changes in version 0.1.1.2-alpha - 2005-07-14
-  o New directory servers:
-    - tor26 has changed IP address.
-
-  o Bugfixes on 0.1.0.x, crashes/leaks:
-    - Port the servers-not-obeying-their-exit-policies fix from 0.1.0.11.
-    - Fix an fd leak in start_daemon().
-    - On Windows, you can't always reopen a port right after you've
-      closed it. So change retry_listeners() to only close and re-open
-      ports that have changed.
-    - Fix a possible double-free in tor_gzip_uncompress().
-
-  o Bugfixes on 0.1.0.x, usability:
-    - When tor_socketpair() fails in Windows, give a reasonable
-      Windows-style errno back.
-    - Let people type "tor --install" as well as "tor -install" when they
-      want to make it an NT service.
-    - NT service patch from Matt Edman to improve error messages.
-    - When the controller asks for a config option with an abbreviated
-      name, give the full name in our response.
-    - Correct the man page entry on TrackHostExitsExpire.
-    - Looks like we were never delivering deflated (i.e. compressed)
-      running-routers lists, even when asked. Oops.
-    - When --disable-threads is set, do not search for or link against
-      pthreads libraries.
-
-  o Bugfixes on 0.1.1.x:
-    - Fix a seg fault with autodetecting which controller version is
-      being used.
-
-  o Features:
-    - New hidden service descriptor format: put a version in it, and
-      let people specify introduction/rendezvous points that aren't
-      in "the directory" (which is subjective anyway).
-    - Allow the DEBUG controller event to work again. Mark certain log
-      entries as "don't tell this to controllers", so we avoid cycles.
-
-
-Changes in version 0.1.1.1-alpha - 2005-06-29
-  o Bugfixes:
-    - Make OS X init script check for missing argument, so we don't
-      confuse users who invoke it incorrectly.
-    - Fix a seg fault in "tor --hash-password foo".
-    - Fix a possible way to DoS dirservers.
-    - When we complain that your exit policy implicitly allows local or
-      private address spaces, name them explicitly so operators can
-      fix it.
-    - Make the log message less scary when all the dirservers are
-      temporarily unreachable.
-    - We were printing the number of idle dns workers incorrectly when
-      culling them.
-
-  o Features:
-    - Revised controller protocol (version 1) that uses ascii rather
-      than binary. Add supporting libraries in python and java so you
-      can use the controller from your applications without caring how
-      our protocol works.
-    - Spiffy new support for crypto hardware accelerators. Can somebody
-      test this?
-

 Changes in version 0.1.0.17 - 2006-02-17
   o Crash bugfixes on 0.1.0.x:
     - When servers with a non-zero DirPort came out of hibernation,
