This is designed to help set network parameters. + Implements proposal 167. + - Tor now reads the "circwindow" parameter out of the consensus, + and uses that value for its circuit package window rather than the + default of 1000 cells. Begins the implementation of proposal 168. + + o Minor bugfixes: + - Fix an extremely rare infinite recursion bug that could occur if + we tried to log a message after shutting down the log subsystem. + Found by Matt Edman. Bugfix on 0.2.0.16-alpha. + - Fix parsing for memory or time units given without a space between + the number and the unit. Bugfix on 0.2.2.1-alpha; fixes bug 1076. + + +Changes in version 0.2.2.1-alpha - 2009-08-26 + o Security fixes: + - Start the process of disabling ".exit" address notation, since it + can be used for a variety of esoteric application-level attacks + on users. To reenable it, set "AllowDotExit 1" in your torrc. Fix + on 0.0.9rc5. + + o New directory authorities: + - Set up urras (run by Jacob Appelbaum) as the seventh v3 directory + authority. + + o Major features: + - New AccelName and AccelDir options add support for dynamic OpenSSL + hardware crypto acceleration engines. + - Tor now supports tunneling all of its outgoing connections over + a SOCKS proxy, using the SOCKS4Proxy and/or SOCKS5Proxy + configuration options. Code by Christopher Davis. + + o Major bugfixes: + - Send circuit or stream sendme cells when our window has decreased + by 100 cells, not when it has decreased by 101 cells. Bug uncovered + by Karsten when testing the "reduce circuit window" performance + patch. Bugfix on the 54th commit on Tor -- from July 2002, + before the release of Tor 0.0.0. This is the new winner of the + oldest-bug prize. + + o New options for gathering stats safely: + - Directories that set "DirReqStatistics 1" write statistics on + directory request to disk every 24 hours. As compared to the + --enable-geoip-stats flag in 0.2.1.x, there are a few improvements: + 1) stats are written to disk exactly every 24 hours; 2) estimated + shares of v2 and v3 requests are determined as mean values, not at + the end of a measurement period; 3) unresolved requests are listed + with country code '??'; 4) directories also measure download times. + - Exit nodes that set "ExitPortStatistics 1" write statistics on the + number of exit streams and transferred bytes per port to disk every + 24 hours. + - Relays that set "CellStatistics 1" write statistics on how long + cells spend in their circuit queues to disk every 24 hours. + - Entry nodes that set "EntryStatistics 1" write statistics on the + rough number and origins of connecting clients to disk every 24 + hours. + - Relays that write any of the above statistics to disk and set + "ExtraInfoStatistics 1" include the past 24 hours of statistics in + their extra-info documents. + + o Minor features: + - New --digests command-line switch to output the digests of the + source files Tor was built with. + - The "torify" script now uses torsocks where available. + - The memarea code now uses a sentinel value at the end of each area + to make sure nothing writes beyond the end of an area. This might + help debug some conceivable causes of bug 930. + - Time and memory units in the configuration file can now be set to + fractional units. For example, "2.5 GB" is now a valid value for + AccountingMax. + - Certain Tor clients (such as those behind check.torproject.org) may + want to fetch the consensus in an extra early manner. To enable this + a user may now set FetchDirInfoExtraEarly to 1. This also depends on + setting FetchDirInfoEarly to 1. Previous behavior will stay the same + as only certain clients who must have this information sooner should + set this option. + - Instead of adding the svn revision to the Tor version string, report + the git commit (when we're building from a git checkout). + + o Minor bugfixes: + - If any the v3 certs we download are unparseable, we should actually + notice the failure so we don't retry indefinitely. Bugfix on + 0.2.0.x; reported by "rotator". + - If the cached cert file is unparseable, warn but don't exit. + - Fix possible segmentation fault on directory authorities. Bugfix on + 0.2.1.14-rc. + - When Tor fails to parse a descriptor of any kind, dump it to disk. + Might help diagnosing bug 1051. + + o Deprecated and removed features: + - The controller no longer accepts the old obsolete "addr-mappings/" + or "unregistered-servers-" GETINFO values. + - Hidden services no longer publish version 0 descriptors, and clients + do not request or use version 0 descriptors. However, the old hidden + service authorities still accept and serve version 0 descriptors + when contacted by older hidden services/clients. + - The EXTENDED_EVENTS and VERBOSE_NAMES controller features are now + always on; using them is necessary for correct forward-compatible + controllers. + - Remove support for .noconnect style addresses. Nobody was using + them, and they provided another avenue for detecting Tor users + via application-level web tricks. + + o Packaging changes: + - Upgrade Vidalia from 0.1.15 to 0.2.3 in the Windows and OS X + installer bundles. See + https://trac.vidalia-project.net/browser/vidalia/tags/vidalia-0.2.3/CHANGELOG + for details of what's new in Vidalia 0.2.3. + - Windows Vidalia Bundle: update Privoxy from 3.0.6 to 3.0.14-beta. + - OS X Vidalia Bundle: move to Polipo 1.0.4 with Tor specific + configuration file, rather than the old Privoxy. + - OS X Vidalia Bundle: Vidalia, Tor, and Polipo are compiled as + x86-only for better compatibility with OS X 10.6, aka Snow Leopard. + - OS X Tor Expert Bundle: Tor is compiled as x86-only for + better compatibility with OS X 10.6, aka Snow Leopard. + - OS X Vidalia Bundle: The multi-package installer is now replaced + by a simple drag and drop to the /Applications folder. This change + occurred with the upgrade to Vidalia 0.2.3. + + Changes in version 0.2.1.20 - 2009-??-?? o Major bugfixes: - Send circuit or stream sendme cells when our window has decreased |
