For a list of changes since + 0.4.6.4-rc, see the ChangeLog file. + + o Major features (control port, onion services): + - Add controller support for creating version 3 onion services with + client authorization. Previously, only v2 onion services could be + created with client authorization. Closes ticket 40084. Patch by + Neel Chauhan. + + o Major features (directory authority): + - When voting on a relay with a Sybil-like appearance, add the Sybil + flag when clearing out the other flags. This lets a relay operator + know why their relay hasn't been included in the consensus. Closes + ticket 40255. Patch by Neel Chauhan. + + o Major features (metrics): + - Relays now report how overloaded they are in their extrainfo + documents. This information is controlled with the + OverloadStatistics torrc option, and it will be used to improve + decisions about the network's load balancing. Implements proposal + 328; closes ticket 40222. + + o Major features (relay, denial of service): + - Add a new DoS subsystem feature to control the rate of client + connections for relays. Closes ticket 40253. + + o Major features (statistics): + - Relays now publish statistics about the number of v3 onion + services and volume of v3 onion service traffic, in the same + manner they already do for v2 onions. Closes ticket 23126. + + o Major bugfixes (circuit build timeout): + - Improve the accuracy of our circuit build timeout calculation for + 60%, 70%, and 80% build rates for various guard choices. We now + use a maximum likelihood estimator for Pareto parameters of the + circuit build time distribution, instead of a "right-censored + estimator". This causes clients to ignore circuits that never + finish building in their timeout calculations. Previously, clients + were counting such unfinished circuits as having the highest + possible build time value, when in reality these circuits most + likely just contain relays that are offline. We also now wait a + bit longer to let circuits complete for measurement purposes, + lower the minimum possible effective timeout from 1.5 seconds to + 10ms, and increase the resolution of the circuit build time + histogram from 50ms bin widths to 10ms bin widths. Additionally, + we alter our estimate Xm by taking the maximum of the top 10 most + common build time values of the 10ms histogram, and compute Xm as + the average of these. Fixes bug 40168; bugfix on 0.2.2.14-alpha. + - Remove max_time calculation and associated warning from circuit + build timeout 'alpha' parameter estimation, as this is no longer + needed by our new estimator from 40168. Fixes bug 34088; bugfix + on 0.2.2.9-alpha. + + o Major bugfixes (signing key): + - In the tor-gencert utility, give an informative error message if + the passphrase given in `--create-identity-key` is too short. + Fixes bug 40189; bugfix on 0.2.0.1-alpha. Patch by Neel Chauhan. + + o Minor features (bridge): + - We now announce the URL to Tor's new bridge status at + https://bridges.torproject.org/ when Tor is configured to run as a + bridge relay. Closes ticket 30477. + + o Minor features (build system): + - New "make lsp" command to auto generate the compile_commands.json + file used by the ccls server. The "bear" program is needed for + this. Closes ticket 40227. + + o Minor features (client): + - Clients now check whether their streams are attempting to re-enter + the Tor network (i.e. to send Tor traffic over Tor), and close + them preemptively if they think exit relays will refuse them for + this reason. See ticket 2667 for details. Closes ticket 40271. + + o Minor features (command line): + - Add long format name "--torrc-file" equivalent to the existing + command-line option "-f". Closes ticket 40324. Patch by + Daniel Pinto. + + o Minor features (command-line interface): + - Add build informations to `tor --version` in order to ease + reproducible builds. Closes ticket 32102. + - When parsing command-line flags that take an optional argument, + treat the argument as absent if it would start with a '-' + character. Arguments in that form are not intelligible for any of + our optional-argument flags. Closes ticket 40223. + - Allow a relay operator to list the ed25519 keys on the command + line by adding the `rsa` and `ed25519` arguments to the + --list-fingerprint flag to show the respective RSA and ed25519 + relay fingerprint. Closes ticket 33632. Patch by Neel Chauhan. + + o Minor features (compatibility): + - Remove an assertion function related to TLS renegotiation. It was + used nowhere outside the unit tests, and it was breaking + compilation with recent alpha releases of OpenSSL 3.0.0. Closes + ticket 40399. + + o Minor features (control port, stream handling): + - Add the stream ID to the event line in the ADDRMAP control event. + Closes ticket 40249. Patch by Neel Chauhan. + + o Minor features (dormant mode): + - Add a new 'DormantTimeoutEnabled' option to allow coarse-grained + control over whether the client ever becomes dormant from + inactivity. Most people won't need this. Closes ticket 40228. + - Add a new 'DormantTimeoutEnabled' option for coarse-grained + control over whether the client can become dormant from + inactivity.

Closes ticket 40373. + + o Minor features (performance, windows): + - Use SRWLocks to implement locking on Windows. Replaces the + "critical section" locking implementation with the faster + SRWLocks, available since Windows Vista. Closes ticket 17927. + Patch by Daniel Pinto. + + o Minor features (protocol, proxy support, defense in depth): + - Close HAProxy connections if they somehow manage to send us data + before we start reading.

Patch from + Samanta Navarro. + + o Minor features (vote document): + - Add a "stats" line to directory authority votes, to report various + statistics that authorities compute about the relays. This will + help us diagnose the network better. Closes ticket 40314. + + o Minor bugfixes (build): + - The configure script now shows whether or not lzma and zstd have + been used, not just if the enable flag was passed in. Fixes bug + 40236; bugfix on 0.4.3.1-alpha. + + o Minor bugfixes (compatibility): + - Fix a failure in the test cases when running on the "hppa" + architecture, along with a related test that might fail on other + architectures in the future. Fixes bug 40274; bugfix + on 0.2.5.1-alpha. + + o Minor bugfixes (compilation): + - Fix a compilation warning about unused functions when building + with a libc that lacks the GLOB_ALTDIRFUNC constant. Fixes bug + 40354; bugfix on 0.4.5.1-alpha. Patch by Daniel Pinto. + + o Minor bugfixes (consensus handling): + - Avoid a set of bugs that could be caused by inconsistently + preferring an out-of-date consensus stored in a stale directory + cache over a more recent one stored on disk as the latest + consensus. Fixes bug 40375; bugfix on 0.3.1.1-alpha. + + o Minor bugfixes (control, sandbox): + - Allow the control command SAVECONF to succeed when the seccomp + sandbox is enabled, and make SAVECONF keep only one backup file to + simplify implementation. Previously SAVECONF allowed a large + number of backup files, which made it incompatible with the + sandbox. Fixes bug 40317; bugfix on 0.2.5.4-alpha. Patch by + Daniel Pinto. + + o Minor bugfixes (directory authorities, voting): + - Add a new consensus method (31) to support any future changes that + authorities decide to make to the value of bwweightscale or + maxunmeasuredbw. Previously, there was a bug that prevented the + authorities from parsing these consensus parameters correctly under + most circumstances. Fixes bug 19011; bugfix on 0.2.2.10-alpha. + + o Minor bugfixes (ipv6): + - Allow non-SOCKSPorts to disable IPv4, IPv6, and PreferIPv4. Some + rare configurations might break, but in this case you can disable + NoIPv4Traffic and NoIPv6Traffic as needed. Fixes bug 33607; bugfix + on 0.4.1.1-alpha. Patch by Neel Chauhan. + + o Minor bugfixes (key generation): + - Do not require a valid torrc when using the `--keygen` argument to + generate a signing key. This allows us to generate keys on systems + or users which may not run Tor. Fixes bug 40235; bugfix on + 0.2.7.2-alpha. Patch by Neel Chauhan. + + o Minor bugfixes (logging, relay): + - Emit a warning if an Address is found to be internal and tor can't + use it. Fixes bug 40290; bugfix on 0.4.5.1-alpha. + + o Minor bugfixes (metrics port): + - Fix a bug that made tor try to re-bind() on an already open + MetricsPort every 60 seconds. Fixes bug 40370; bugfix + on 0.4.5.1-alpha. + + o Minor bugfixes (onion services, logging): + - Downgrade the severity of a few rendezvous circuit-related + warnings from warning to info. Fixes bug 40207; bugfix on + 0.3.2.1-alpha. Patch by Neel Chauhan. + + o Minor bugfixes (relay): + - Reduce the compression level for data streaming from HIGH to LOW. + This should reduce the CPU and memory burden for directory caches. + Fixes bug 40301; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (testing, BSD): + - Fix pattern-matching errors when patterns expand to invalid paths + on BSD systems. Fixes bug 40318; bugfix on 0.4.5.1-alpha. Patch by + Daniel Pinto. + + o Code simplification and refactoring: + - Remove the orconn_ext_or_id_map structure and related functions. + (Nothing outside of unit tests used them.) Closes ticket 33383. + Patch by Neel Chauhan. + + o Removed features: + - Remove unneeded code for parsing private keys in directory + documents. This code was only used for client authentication in v2 + onion services, which are now unsupported. Closes ticket 40374. + - As of this release, Tor no longer supports the old v2 onion + services. They were deprecated last July for security, and support + will be removed entirely later this year. We strongly encourage + everybody to migrate to v3 onion services. For more information, + see https://blog.torproject.org/v2-deprecation-timeline . Closes + ticket 40266. (NOTE: We accidentally released an earlier version + of the 0.4.6.1-alpha changelog without this entry. Sorry for + the confusion!) + + o Code simplification and refactoring (metrics, DoS): + - Move the DoS subsystem into the subsys manager, including its + configuration options. Closes ticket 40261. + + o Documentation (manual): + - Move the ServerTransport* options to the "SERVER OPTIONS" section. + Closes issue 40331. + - Indicate that the HiddenServiceStatistics option also applies to + bridges. Closes ticket 40346. + - Move the description of BridgeRecordUsageByCountry to the section + "STATISTICS OPTIONS". Closes ticket 40323. + + o Removed features (relay): + - Because DirPorts are only used on authorities, relays no longer + advertise them. Similarly, self-testing for DirPorts has been + disabled, since an unreachable DirPort is no reason for a relay + not to advertise itself. (Configuring a DirPort will still work, + for now.) Closes ticket 40282. + + Changes in version 0.4.5.8 - 2021-05-10 Tor 0.4.5.8 fixes several bugs in earlier version, backporting fixes from the 0.4.6.x series.
