Release notes in progress for 0.0.8: Changes in version 0.0.8 - 2004-08-25
rc2:
o Make it compile on cygwin again.
o When picking unverified routers, skip those with low uptime and/or
low bandwidth, depending on what properties you care about.
rc1:
o Changes from 0.0.7.3:
- Bugfixes:
- Fix assert triggers: if the other side returns an address 0.0.0.0,
don't put it into the client dns cache.
- If a begin failed due to exit policy, but we believe the IP
address should have been allowed, switch that router to exitpolicy
reject *:* until we get our next directory.
- Features:
- Clients choose nodes proportional to advertised bandwidth.
- Avoid using nodes with low uptime as introduction points.
- Handle servers with dynamic IP addresses: don't replace
options->Address with the resolved one at startup, and
detect our address right before we make a routerinfo each time.
- 'FascistFirewall' option to pick dirservers and ORs on specific
ports; plus 'FirewallPorts' config option to tell FascistFirewall
which ports are open. (Defaults to 80,443)
- Be more aggressive about trying to make circuits when the network
has changed (e.g. when you unsuspend your laptop).
- Check for time skew on http headers; report date in response to
"GET /".
- If the entrynode config line has only one node, don't pick it as
an exitnode.
- Add strict{entry|exit}nodes config options. If set to 1, then
we refuse to build circuits that don't include the specified entry
or exit nodes.
- OutboundBindAddress config option, to bind to a specific
IP address for outgoing connect()s.
- End truncated log entries (e.g. directories) with "[truncated]".
o Patches to 0.0.8preX:
- Bugfixes:
- Patches to compile and run on win32 again (maybe)?
- Fix crash when looking for ~/.torrc with no $HOME set.
- Fix a race bug in the unit tests.
- Handle verified/unverified name collisions better when new
routerinfo's arrive in a directory.
- Sometimes routers were getting entered into the stats before
we'd assigned their identity_digest. Oops.
- Only pick and establish intro points after we've gotten a
directory.
- Features:
- AllowUnverifiedNodes config option to let circuits choose no-name
routers in entry,middle,exit,introduction,rendezvous positions.
Allow middle and rendezvous positions by default.
- Add a man page for tor-resolve.
pre3:
o Changes from 0.0.7.2:
- Allow multiple ORs with same nickname in routerlist -- now when
people give us one identity key for a nickname, then later
another, we don't constantly complain until the first expires.
- Remember used bandwidth (both in and out), and publish 15-minute
snapshots for the past day into our descriptor.
- You can now fetch $DIRURL/running-routers to get just the
running-routers line, not the whole descriptor list. (But
clients don't use this yet.)
- When people mistakenly use Tor as an http proxy, point them
at the tor-doc.html rather than the INSTALL.
- Remove our mostly unused -- and broken -- hex_encode()
function. Use base16_encode() instead. (Thanks to Timo Lindfors
for pointing out this bug.)
- Rotate onion keys every 12 hours, not every 2 hours, so we have
fewer problems with people using the wrong key.
- Change the default exit policy to reject the default edonkey,
kazaa, gnutella ports.
- Add replace_file() to util.[ch] to handle win32's rename().
o Changes from 0.0.8preX:
- Fix two bugs in saving onion keys to disk when rotating, so
hopefully we'll get fewer people using old onion keys.
- Fix an assert error that was making SocksPolicy not work.
- Be willing to expire routers that have an open dirport -- it's
just the authoritative dirservers we want to not forget.
- Reject tor-resolve requests for .onion addresses early, so we
don't build a whole rendezvous circuit and then fail.
- When you're warning a server that he's unverified, don't cry
wolf unpredictably.
- Fix a race condition: don't try to extend onto a connection
that's still handshaking.
- For servers in clique mode, require the conn to be open before
you'll choose it for your path.
- Fix some cosmetic bugs about duplicate mark-for-close, lack of
end relay cell, etc.
- Measure bandwidth capacity over the last 24 hours, not just 12
- Bugfix: authoritative dirservers were making and signing a new
directory for each client, rather than reusing the cached one.
pre2:
o Changes from 0.0.7.2:
- Security fixes:
- Check directory signature _before_ you decide whether you're
you're running an obsolete version and should exit.
- Check directory signature _before_ you parse the running-routers
list to decide who's running or verified.
- Bugfixes and features:
- Check return value of fclose while writing to disk, so we don't
end up with broken files when servers run out of disk space.
- Log a warning if the user uses an unsafe socks variant, so people
are more likely to learn about privoxy or socat.
- Dirservers now include RFC1123-style dates in the HTTP headers,
which one day we will use to better detect clock skew.
o Changes from 0.0.8pre1:
- Make it compile without warnings again on win32.
- Log a warning if you're running an unverified server, to let you
know you might want to get it verified.
- Only pick a default nickname if you plan to be a server.
