Otherwise, there is a chance that we're building + a circuit that's worth attacking by an adversary who finds + breaking 1024-bit crypto doable, and that chance changes the game + theory. Implements ticket 9777. + - Clients now look at the "usecreatefast" consensus parameter to + decide whether to use CREATE_FAST or CREATE cells for the first hop + of their circuit. This approach can improve security on connections + where Tor's circuit handshake is stronger than the available TLS + connection security levels, but the tradeoff is more computational + load on guard relays. Implements proposal 221. Resolves ticket 9386. + + o Major features (bridges): + - Don't launch pluggable transport proxies if we don't have any + bridges configured that would use them. Now we can list many + pluggable transports, and Tor will dynamically start one when it + hears a bridge address that needs it. Resolves ticket 5018. + - The bridge directory authority now assigns status flags (Stable, + Guard, etc) to bridges based on thresholds calculated over all + Running bridges. Now bridgedb can finally make use of its features + to e.g. include at least one Stable bridge in its answers. Fixes + bug 9859. + + o Major features (other): + - Extend ORCONN controller event to include an "ID" parameter, + and add four new controller event types CONN_BW, CIRC_BW, + CELL_STATS, and TB_EMPTY that show connection and circuit usage. + The new events are emitted in private Tor networks only, with the + goal of being able to better track performance and load during + full-network simulations. Implements proposal 218 and ticket 7359. + - On some platforms (currently: recent OSX versions, glibc-based + platforms that support the ELF format, and a few other + Unix-like operating systems), Tor can now dump stack traces + when a crash occurs or an assertion fails. By default, traces + are dumped to stderr (if possible) and to any logs that are + reporting errors. Implements ticket 9299. + + o Major bugfixes: + - Avoid a segfault on SIGUSR1, where we had freed a connection but did + not entirely remove it from the connection lists. Fixes bug 9602; + bugfix on 0.2.4.4-alpha. + - Do not treat streams that fail with reason + END_STREAM_REASON_INTERNAL as indicating a definite circuit failure, + since it could also indicate an ENETUNREACH connection error. Fixes + part of bug 10777; bugfix on 0.2.4.8-alpha.

+ o Minor features (bridges, pluggable transports): + - Add threshold cutoffs to the networkstatus document created by + the Bridge Authority. Fixes bug 1117. + - On Windows, spawn background processes using the CREATE_NO_WINDOW + flag. Now Tor Browser Bundle 3.5 with pluggable transports enabled + doesn't pop up a blank console window. (In Tor Browser Bundle 2.x, + Vidalia set this option for us.) Implements ticket 10297. + + o Minor features (security): + - Always clear OpenSSL bignums before freeing them -- even bignums + that don't contain secrets. Resolves ticket 10793. Patch by + Florent Daigniere. + + o Minor features (config options and command line): + - Add an --allow-missing-torrc commandline option that tells Tor to + run even if the configuration file specified by -f is not available. + Implements ticket 10060. + - Add support for the TPROXY transparent proxying facility on Linux. + See documentation for the new TransProxyType option for more + details. Implementation by "thomo". Closes ticket 10582. + + o Minor features (controller): + - Add a new "HS_DESC" controller event that reports activities + related to hidden service descriptors. Resolves ticket 8510. + - New "DROPGUARDS" controller command to forget all current entry + guards. Not recommended for ordinary use, since replacing guards + too frequently makes several attacks easier. Resolves ticket 9934; + patch from "ra". + + o Minor features (build): + - Assume that a user using ./configure --host wants to cross-compile, + and give an error if we cannot find a properly named + tool-chain. Add a --disable-tool-name-check option to proceed + nevertheless. Addresses ticket 9869. Patch by Benedikt Gollatz. + - If we run ./configure and the compiler recognizes -fstack-protector + but the linker rejects it, warn the user about a potentially missing + libssp package. Addresses ticket 9948. Patch from Benedikt Gollatz. + + o Minor features (testing): + - If Python is installed, "make check" now runs extra tests beyond + the unit test scripts. + - When bootstrapping a test network, sometimes very few relays get + the Guard flag. Now a new option "TestingDirAuthVoteGuard" can + specify a set of relays which should be voted Guard regardless of + their uptime or bandwidth. Addresses ticket 9206. + + o Minor features (log messages): + - When ServerTransportPlugin is set on a bridge, Tor can write more + useful statistics about bridge use in its extrainfo descriptors, + but only if the Extended ORPort ("ExtORPort") is set too. Add a + log message to inform the user in this case. Resolves ticket 9651. + - When receiving a new controller connection, log the origin address. + Resolves ticket 9698; patch from "sigpipe". + - When logging OpenSSL engine status at startup, log the status of + more engines. Fixes ticket 10043; patch from Joshua Datko. + - Turn "circuit handshake stats since last time" log messages into a + heartbeat message. Fixes bug 10485; bugfix on 0.2.4.17-rc. + + o Minor features (new since 0.2.5.1-alpha, also in 0.2.4.18-rc): + - Improve the circuit queue out-of-memory handler. Previously, when + we ran low on memory, we'd close whichever circuits had the most + queued cells. Now, we close those that have the *oldest* queued + cells, on the theory that those are most responsible for us + running low on memory. Based on analysis from a forthcoming paper + by Jansen, Tschorsch, Johnson, and Scheuermann.

Fixes bug 9927. + - Update to the October 2 2013 Maxmind GeoLite Country database. + + o Minor bugfixes (clients): + - When closing a channel that has already been open, do not close + pending circuits that were waiting to connect to the same relay. + Fixes bug 9880; bugfix on 0.2.5.1-alpha. Thanks to skruffy for + finding this bug. + + o Minor bugfixes (relays): + - Treat ENETUNREACH, EACCES, and EPERM connection failures at an + exit node as a NOROUTE error, not an INTERNAL error, since they + can apparently happen when trying to connect to the wrong sort + of netblocks. Fixes part of bug 10777; bugfix on 0.1.0.1-rc. + + o Minor bugfixes (bridges): + - Fix a bug where the first connection works to a bridge that uses a + pluggable transport with client-side parameters, but we don't send + the client-side parameters on subsequent connections. (We don't + use any pluggable transports with client-side parameters yet, + but ScrambleSuit will soon become the first one.) Fixes bug 9162; + bugfix on 0.2.0.3-alpha. Based on a patch from "rl1987". + + o Minor bugfixes (node selection): + - If ExcludeNodes is set, consider non-excluded hidden service + directory servers before excluded ones. Do not consider excluded + hidden service directory servers at all if StrictNodes is + set. (Previously, we would sometimes decide to connect to those + servers, and then realize before we initiated a connection that + we had excluded them.) Fixes bug 10722; bugfix on 0.2.0.10-alpha. + Reported by "mr-4". + - If we set the ExitNodes option but it doesn't include any nodes + that have the Exit flag, we would choose not to bootstrap. Now we + bootstrap so long as ExitNodes includes nodes which can exit to + some port. Fixes bug 10543; bugfix on 0.2.4.10-alpha. + + o Minor bugfixes (controller and command-line): + - If changing a config option via "setconf" fails in a recoverable + way, we used to nonetheless write our new control ports to the + file described by the "ControlPortWriteToFile" option. Now we only + write out that file if we successfully switch to the new config + option. Fixes bug 5605; bugfix on 0.2.2.26-beta. Patch from "Ryman". + - When a command-line option such as --version or --help that + ordinarily implies --hush appears on the command line along with + --quiet, then actually obey --quiet. Previously, we obeyed --quiet + only if it appeared later on the command line. Fixes bug 9578; + bugfix on 0.2.5.1-alpha. + + o Minor bugfixes (code correctness): + - Previously we used two temporary files when writing descriptors to + disk; now we only use one. Fixes bug 1376. + - Remove an erroneous (but impossible and thus harmless) pointer + comparison that would have allowed compilers to skip a bounds + check in channeltls.c. Fixes bugs 10313 and 9980; bugfix on + 0.2.0.10-alpha.
