Using this vulnerability, an attacker could cause Tor + instances to consume a huge amount of CPU, disrupting their operations + for several seconds or minutes. This attack could be launched by + anybody against a relay, or by a directory cache against any client + that had connected to it. The attacker could launch this attack as + much as they wanted, thereby disrupting service or creating patterns + that could aid in traffic analysis. This issue was found by OSS-Fuzz, + and is also tracked as CVE-2020-10592. + + We do not have reason to believe that this attack is currently being + exploited in the wild, but nonetheless we advise everyone to upgrade + as soon as packages are available. + + o Major bugfixes (security, denial-of-service, backport from 0.4.3.3-alpha): + - Fix a denial-of-service bug that could be used by anyone to + consume a bunch of CPU on any Tor relay or authority, or by + directories to consume a bunch of CPU on clients or hidden + services. Because of the potential for CPU consumption to + introduce observable timing patterns, we are treating this as a + high-severity security issue. Fixes bug 33119; bugfix on + 0.2.1.5-alpha. Found by OSS-Fuzz. We are also tracking this issue + as TROVE-2020-002 and CVE-2020-10592. + + o Major bugfixes (circuit padding, memory leak, backport from 0.4.3.3-alpha): + - Avoid a remotely triggered memory leak in the case that a circuit + padding machine is somehow negotiated twice on the same circuit. + Fixes bug 33619; bugfix on 0.4.0.1-alpha. Found by Tobias Pulls. + This is also tracked as TROVE-2020-004 and CVE-2020-10593. + + o Minor bugfixes (bridges, backport from 0.4.3.1-alpha): + - Lowercase the configured value of BridgeDistribution before adding + it to the descriptor. Fixes bug 32753; bugfix on 0.3.2.3-alpha. + + o Minor bugfixes (logging, backport from 0.4.3.2-alpha): + - If we encounter a bug when flushing a buffer to a TLS connection, + only log the bug once per invocation of the Tor process. + Previously we would log with every occurrence, which could cause + us to run out of disk space. Fixes bug 33093; bugfix + on 0.3.2.2-alpha. + + o Minor bugfixes (onion services v3, backport from 0.4.3.3-alpha): + - Fix an assertion failure that could result from a corrupted + ADD_ONION control port command. Found by Saibato. Fixes bug 33137; + bugfix on 0.3.3.1-alpha. This issue is also tracked + as TROVE-2020-003. + + o Minor bugfixes (rust, build, backport from 0.4.3.2-alpha): + - Fix a syntax warning given by newer versions of Rust that was + creating problems for our continuous integration. Fixes bug 33212; + bugfix on 0.3.5.1-alpha. + + o Testing (Travis CI, backport from 0.4.3.3-alpha): + - Remove a redundant distcheck job. Closes ticket 33194. + - Sort the Travis jobs in order of speed: putting the slowest jobs + first takes full advantage of Travis job concurrency. Closes + ticket 33194. + - Stop allowing the Chutney IPv6 Travis job to fail. This job was + previously configured to fast_finish (which requires + allow_failure), to speed up the build. Closes ticket 33195. + - When a Travis chutney job fails, use chutney's new "diagnostics.sh" + tool to produce detailed diagnostic output. Closes ticket 32792. + + +Changes in version 0.4.1.8 - 2020-01-30 + This release backports several bugfixes from later release series, + including some that had affected the Linux seccomp2 sandbox or Windows + services. If you're running with one of those configurations, you'll + probably want to upgrade; otherwise, you should be fine with your + current version of 0.4.1.x. + + o Major bugfixes (linux seccomp sandbox, backport from 0.4.3.1-alpha): + - Correct how we use libseccomp. Particularly, stop assuming that + rules are applied in a particular order or that more rules are + processed after the first match. Neither is the case! In + libseccomp <2.4.0 this lead to some rules having no effect. + libseccomp 2.4.0 changed how rules are generated, leading to a + different ordering, which in turn led to a fatal crash during + startup. Fixes bug 29819; bugfix on 0.2.5.1-alpha. Patch by + Peter Gerber. + - Fix crash when reloading logging configuration while the + experimental sandbox is enabled. Fixes bug 32841; bugfix on + 0.4.1.7. Patch by Peter Gerber. + + o Minor bugfixes (crash, backport form 0.4.2.4-rc): + - When running Tor with an option like --verify-config or + --dump-config that does not start the event loop, avoid crashing + if we try to exit early because of an error. Fixes bug 32407; + bugfix on 0.3.3.1-alpha. + + o Minor bugfixes (windows service, backport from 0.4.3.1-alpha): + - Initialize the publish/subscribe system when running as a windows + service. Fixes bug 32778; bugfix on 0.4.1.1-alpha. + + o Testing (backport from 0.4.3.1-alpha): + - Turn off Tor's Sandbox in Chutney jobs, and run those jobs on + Ubuntu Bionic. Turning off the Sandbox is a work-around, until we + fix the sandbox errors in 32722. Closes ticket 32240. + - Re-enable the Travis CI macOS Chutney build, but don't let it + prevent the Travis job from finishing. (The Travis macOS jobs are + slow, so we don't want to have it delay the whole CI process.) + Closes ticket 32629. + + o Testing (continuous integration, backport from 0.4.3.1-alpha): + - Use zstd in our Travis Linux builds. Closes ticket 32242. + + +Changes in version 0.4.1.7 - 2019-12-09 + This release backports several bugfixes to improve stability and + correctness. Anyone experiencing build problems or crashes with 0.4.1.6, + including all relays relying on AccountingMax, should upgrade. + + o Major features (directory authorities, backport from 0.4.2.2-alpha): + - Directory authorities now reject relays running all currently + deprecated release series. The currently supported release series + are: 0.2.9, 0.3.5, 0.4.0, 0.4.1, and 0.4.2. Closes ticket 31549. + + o Major bugfixes (embedded Tor, backport from 0.4.2.2-alpha): + - Avoid a possible crash when restarting Tor in embedded mode and + enabling a different set of publish/subscribe messages. Fixes bug + 31898; bugfix on 0.4.1.1-alpha. + + o Major bugfixes (relay, backport from 0.4.2.3-alpha): + - Relays now respect their AccountingMax bandwidth again. When + relays entered "soft" hibernation (which typically starts when + we've hit 90% of our AccountingMax), we had stopped checking + whether we should enter hard hibernation. Soft hibernation refuses + new connections and new circuits, but the existing circuits can + continue, meaning that relays could have exceeded their configured + AccountingMax. Fixes bug 32108; bugfix on 0.4.0.1-alpha. + + o Major bugfixes (torrc parsing, backport from 0.4.2.2-alpha): + - Stop ignoring torrc options after an %include directive, when the + included directory ends with a file that does not contain any + config options (but does contain comments or whitespace). Fixes + bug 31408; bugfix on 0.3.1.1-alpha. + + o Major bugfixes (v3 onion services, backport from 0.4.2.3-alpha): + - Onion services now always use the exact number of intro points + configured with the HiddenServiceNumIntroductionPoints option (or + fewer if nodes are excluded). Before, a service could sometimes + pick more intro points than configured. Fixes bug 31548; bugfix + on 0.3.2.1-alpha. + + o Minor features (continuous integration, backport from 0.4.2.2-alpha): + - When building on Appveyor and Travis, pass the "-k" flag to make, + so that we are informed of all compilation failures, not just the + first one or two. Closes ticket 31372. + + o Minor features (geoip, backport from 0.4.2.5): + - Update geoip and geoip6 to the December 3 2019 Maxmind GeoLite2 + Country database. Closes ticket 32685. + + o Minor bugfixes (Appveyor CI, backport from 0.4.2.2-alpha): + - Avoid spurious errors when Appveyor CI fails before the install step. + Fixes bug 31884; bugfix on 0.3.4.2-alpha. + + o Minor bugfixes (client, onion service v3, backport from 0.4.2.4-rc): + - Fix a BUG() assertion that occurs within a very small race window + between when a client intro circuit opens and when its descriptor + gets cleaned up from the cache. The circuit is now closed early, + which will trigger a re-fetch of the descriptor and continue the + connection. Fixes bug 28970; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (connections, backport from 0.4.2.3-rc): + - Avoid trying to read data from closed connections, which can cause + needless loops in Libevent and infinite loops in Shadow. Fixes bug + 30344; bugfix on 0.1.1.1-alpha. + + o Minor bugfixes (error handling, backport from 0.4.2.1-alpha): + - On abort, try harder to flush the output buffers of log messages. + On some platforms (macOS), log messages could be discarded when + the process terminates. Fixes bug 31571; bugfix on 0.3.5.1-alpha. + - Report the tor version whenever an assertion fails. Previously, we + only reported the Tor version on some crashes, and some non-fatal + assertions. Fixes bug 31571; bugfix on 0.3.5.1-alpha. + - When tor aborts due to an error, close log file descriptors before + aborting. Closing the logs makes some OSes flush log file buffers, + rather than deleting buffered log lines. Fixes bug 31594; bugfix + on 0.2.5.2-alpha. + + o Minor bugfixes (logging, backport from 0.4.2.2-alpha): + - Add a missing check for HAVE_PTHREAD_H, because the backtrace code + uses mutexes. Fixes bug 31614; bugfix on 0.2.5.2-alpha. + - Disable backtrace signal handlers when shutting down tor. Fixes + bug 31614; bugfix on 0.2.5.2-alpha. + - Rate-limit our the logging message about the obsolete .exit + notation. Previously, there was no limit on this warning, which + could potentially be triggered many times by a hostile website. + Fixes bug 31466; bugfix on 0.2.2.1-alpha. + + o Minor bugfixes (logging, protocol violations, backport from 0.4.2.2-alpha): + - Do not log a nonfatal assertion failure when receiving a VERSIONS + cell on a connection using the obsolete v1 link protocol. Log a + protocol_warn instead. Fixes bug 31107; bugfix on 0.2.4.4-alpha. + + o Minor bugfixes (mainloop, periodic events, in-process API, backport from 0.4.2.3-alpha): + - Reset the periodic events' "enabled" flag when Tor is shut down + cleanly. Previously, this flag was left on, which caused periodic + events not to be re-enabled when Tor was relaunched in-process + with tor_api.h after a shutdown. Fixes bug 32058; bugfix + on 0.3.3.1-alpha. + + o Minor bugfixes (multithreading, backport from 0.4.2.2-alpha): + - Avoid some undefined behaviour when freeing mutexes. Fixes bug + 31736; bugfix on 0.0.7. + + o Minor bugfixes (process management, backport from 0.4.2.3-alpha): + - Remove overly strict assertions that triggered when a pluggable + transport failed to launch. Fixes bug 31091; bugfix + on 0.4.0.1-alpha. + - Remove an assertion in the Unix process backend. This assertion + would trigger when we failed to find the executable for a child + process. Fixes bug 31810; bugfix on 0.4.0.1-alpha. + + o Minor bugfixes (relay, backport from 0.4.2.2-alpha): + - Avoid crashing when starting with a corrupt keys directory where + the old ntor key and the new ntor key are identical. Fixes bug + 30916; bugfix on 0.2.4.8-alpha. + + o Minor bugfixes (testing, backport from 0.4.2.3-alpha): + - When testing port rebinding, don't busy-wait for tor to log. + Instead, actually sleep for a short time before polling again. + Also improve the formatting of control commands and log messages. + Fixes bug 31837; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (tests, SunOS, backport from 0.4.2.2-alpha): + - Avoid a map_anon_nofork test failure due to a signed/unsigned + integer comparison. Fixes bug 31897; bugfix on 0.4.1.1-alpha. + + o Minor bugfixes (tls, logging, backport from 0.4.2.3-alpha): + - Log bugs about the TLS read buffer's length only once, rather than + filling the logs with similar warnings. Fixes bug 31939; bugfix + on 0.3.0.4-rc. + + o Documentation (backport from 0.4.2.2-alpha): + - Explain why we can't destroy the backtrace buffer mutex. Explain + why we don't need to destroy the log mutex. Closes ticket 31736. + + o Testing (continuous integration, backport from 0.4.2.3-alpha): + - Disable all but one Travis CI macOS build, to mitigate slow + scheduling of Travis macOS jobs. Closes ticket 32177. + - Run the chutney IPv6 networks as part of Travis CI. Closes + ticket 30860. + - Simplify the Travis CI build matrix, and optimise for build time. + Closes ticket 31859. + - Use Windows Server 2019 instead of Windows Server 2016 in our + Appveyor builds. Closes ticket 32086. + + o Testing (continuous integration, backport from 0.4.2.4-rc): + - In Travis, use Xcode 11.2 on macOS 10.14. Closes ticket 32241. + - Use Ubuntu Bionic images for our Travis CI builds, so we can get a + recent version of coccinelle. But leave chutney on Ubuntu Trusty, + until we can fix some Bionic permissions issues (see ticket + 32240). Related to ticket 31919. + - Install the mingw OpenSSL package in Appveyor. This makes sure + that the OpenSSL headers and libraries match in Tor's Appveyor + builds. (This bug was triggered by an Appveyor image update.) + Fixes bug 32449; bugfix on 0.3.5.6-rc. + + o Testing (continuous integration, backport from 0.4.2.5): + - Require C99 standards-conforming code in Travis CI, but allow GNU gcc + extensions. Also activates clang's -Wtypedef-redefinition warnings. + Build some jobs with -std=gnu99, and some jobs without. + Closes ticket 32500. + + +Changes in version 0.4.1.6 - 2019-09-19 + This release backports several bugfixes to improve stability and + correctness. Anyone experiencing build problems or crashes with 0.4.1.5, + or experiencing reliability issues with single onion services, should + upgrade. + + o Major bugfixes (crash, Linux, Android, backport from 0.4.2.1-alpha): + - Tolerate systems (including some Android installations) where + madvise and MADV_DONTDUMP are available at build-time, but not at + run time. Previously, these systems would notice a failed syscall + and abort. Fixes bug 31570; bugfix on 0.4.1.1-alpha. + - Tolerate systems (including some Linux installations) where + madvise and/or MADV_DONTFORK are available at build-time, but not + at run time. Previously, these systems would notice a failed + syscall and abort. Fixes bug 31696; bugfix on 0.4.1.1-alpha. + + o Minor features (stem tests, backport from 0.4.2.1-alpha): + - Change "make test-stem" so it only runs the stem tests that use + tor. This change makes test-stem faster and more reliable. Closes + ticket 31554. + + o Minor bugfixes (build system, backport form 0.4.2.1-alpha): + - Do not include the deprecated <sys/sysctl.h> on Linux or Windows + systems. Fixes bug 31673; bugfix on 0.2.5.4-alpha. + + o Minor bugfixes (compilation, backport from 0.4.2.1-alpha): + - Add more stub functions to fix compilation on Android with link- + time optimization when --disable-module-dirauth is used. + Previously, these compilation settings would make the compiler + look for functions that didn't exist. Fixes bug 31552; bugfix + on 0.4.1.1-alpha. + - Suppress spurious float-conversion warnings from GCC when calling + floating-point classifier functions on FreeBSD. Fixes part of bug + 31687; bugfix on 0.3.1.5-alpha. + + o Minor bugfixes (controller protocol): + - Fix the MAPADDRESS controller command to accept one or more + arguments. Previously, it required two or more arguments, and ignored + the first. Fixes bug 31772; bugfix on 0.4.1.1-alpha. + + o Minor bugfixes (FreeBSD, PF-based proxy, IPv6, backport from 0.4.2.1-alpha): + - When extracting an IPv6 address from a PF-based proxy, verify that + we are actually configured to receive an IPv6 address, and log an + internal error if not. Fixes part of bug 31687; bugfix + on 0.2.3.4-alpha. + + o Minor bugfixes (guards, backport from 0.4.2.1-alpha): + - When tor is missing descriptors for some primary entry guards, + make the log message less alarming. It's normal for descriptors to + expire, as long as tor fetches new ones soon after. Fixes bug + 31657; bugfix on 0.3.3.1-alpha. + + o Minor bugfixes (logging, backport from 0.4.2.1-alpha): + - Change log level of message "Hash of session info was not as + expected" to LOG_PROTOCOL_WARN. Fixes bug 12399; bugfix + on 0.1.1.10-alpha. + + o Minor bugfixes (rust, backport from 0.4.2.1-alpha): + - Correctly exclude a redundant rust build job in Travis. Fixes bug + 31463; bugfix on 0.3.5.4-alpha. + + o Minor bugfixes (v2 single onion services, backport from 0.4.2.1-alpha): + - Always retry v2 single onion service intro and rend circuits with + a 3-hop path. Previously, v2 single onion services used a 3-hop + path when rendezvous circuits were retried after a remote or + delayed failure, but a 1-hop path for immediate retries. Fixes bug + 23818; bugfix on 0.2.9.3-alpha. + + o Minor bugfixes (v3 single onion services, backport from 0.4.2.1-alpha): + - Always retry v3 single onion service intro and rend circuits with + a 3-hop path. Previously, v3 single onion services used a 3-hop + path when rend circuits were retried after a remote or delayed + failure, but a 1-hop path for immediate retries. Fixes bug 23818; + bugfix on 0.3.2.1-alpha. + - Make v3 single onion services fall back to a 3-hop intro, when all + intro points are unreachable via a 1-hop path. Previously, v3 + single onion services failed when all intro nodes were unreachable + via a 1-hop path. Fixes bug 23507; bugfix on 0.3.2.1-alpha. + + o Documentation (backport from 0.4.2.1-alpha): + - Use RFC 2397 data URL scheme to embed an image into tor-exit- + notice.html so that operators no longer have to host it + themselves. Closes ticket 31089. + + +Changes in version 0.4.1.5 - 2019-08-20 + This is the first stable release in the 0.4.1.x series. This series + adds experimental circuit-level padding, authenticated SENDME cells to + defend against certain attacks, and several performance improvements + to save on CPU consumption. It fixes bugs in bootstrapping and v3 + onion services. It also includes numerous smaller features and + bugfixes on earlier versions. + + Per our support policy, we will support the 0.4.1.x series for nine + months, or until three months after the release of a stable 0.4.2.x: + whichever is longer. If you need longer-term support, please stick + with 0.3.5.x, which will we plan to support until Feb 2022. + + Below are the changes since 0.4.1.4-rc. For a complete list of changes + since 0.4.0.5, see the ReleaseNotes file. + + o Directory authority changes: + - The directory authority "dizum" has a new IP address. Closes + ticket 31406. + + o Minor features (circuit padding logging): + - Demote noisy client-side warn logs about circuit padding to + protocol warnings. Add additional log messages and circuit ID + fields to help with bug 30992 and any other future issues. + + o Minor bugfixes (circuit padding negotiation): + - Bump the circuit padding protocol version to explicitly signify + that the HS setup machine support is finalized in 0.4.1.x-stable. + This also means that 0.4.1.x-alpha clients will not negotiate + padding with 0.4.1.x-stable relays, and 0.4.1.x-stable clients + will not negotiate padding with 0.4.1.x-alpha relays (or 0.4.0.x + relays). Fixes bug 31356; bugfix on 0.4.1.1-alpha. + + o Minor bugfixes (circuit padding): + - Ignore non-padding cells on padding circuits. This addresses + various warning messages from subsystems that were not expecting + padding circuits. Fixes bug 30942; bugfix on 0.4.1.1-alpha. + + o Minor bugfixes (clock skew detection): + - Don't believe clock skew results from NETINFO cells that appear to + arrive before we sent the VERSIONS cells they are responding to. + Previously, we would accept them up to 3 minutes "in the past". + Fixes bug 31343; bugfix on 0.2.4.4-alpha. + + o Minor bugfixes (compatibility, standards compliance): + - Fix a bug that would invoke undefined behavior on certain + operating systems when trying to asprintf() a string exactly + INT_MAX bytes long. We don't believe this is exploitable, but it's + better to fix it anyway. Fixes bug 31001; bugfix on 0.2.2.11-alpha. + Found and fixed by Tobias Stoeckmann. + + o Minor bugfixes (compilation warning): + - Fix a compilation warning on Windows about casting a function + pointer for GetTickCount64(). Fixes bug 31374; bugfix + on 0.2.9.1-alpha. + + o Minor bugfixes (compilation): + - Avoid using labs() on time_t, which can cause compilation warnings + on 64-bit Windows builds. Fixes bug 31343; bugfix on 0.2.4.4-alpha. + + o Minor bugfixes (distribution): + - Do not ship any temporary files found in the + scripts/maint/practracker directory. Fixes bug 31311; bugfix + on 0.4.1.1-alpha. + + o Testing (continuous integration): + - In Travis, make stem log a controller trace to the console, and + tail stem's tor log after failure. Closes ticket 30591. + - In Travis, only run the stem tests that use a tor binary. Closes + ticket 30694. + + +Changes in version 0.4.1.4-rc - 2019-07-25 + Tor 0.4.1.4-rc fixes a few bugs from previous versions of Tor, and + updates to a new list of fallback directories. If no new bugs are + found, the next release in the 0.4.1.x serious should be stable. + + o Major bugfixes (circuit build, guard): + - When considering upgrading circuits from "waiting for guard" to + "open", always ignore circuits that are marked for close. Otherwise, + we can end up in the situation where a subsystem is notified that + a closing circuit has just opened, leading to undesirable + behavior. Fixes bug 30871; bugfix on 0.3.0.1-alpha. + + o Minor features (continuous integration): + - Our Travis configuration now uses Chutney to run some network + integration tests automatically. Closes ticket 29280. + + o Minor features (fallback directory list): + - Replace the 157 fallbacks originally introduced in Tor 0.3.5.6-rc + in December 2018 (of which ~122 were still functional), with a + list of 148 fallbacks (70 new, 78 existing, 79 removed) generated + in June 2019. Closes ticket 28795. + + o Minor bugfixes (circuit padding): + - On relays, properly check that a padding machine is absent before + logging a warning about it being absent. Fixes bug 30649; bugfix + on 0.4.0.1-alpha. + - Add two NULL checks in unreachable places to silence Coverity (CID + 144729 and 1447291) and better future-proof ourselves. Fixes bug + 31024; bugfix on 0.4.1.1-alpha. + + o Minor bugfixes (crash on exit): + - Avoid a set of possible code paths that could try to use freed + memory in routerlist_free() while Tor was exiting. Fixes bug + 31003; bugfix on 0.1.2.2-alpha. + + o Minor bugfixes (logging): + - Fix a conflict between the flag used for messaging-domain log + messages, and the LD_NO_MOCK testing flag. Fixes bug 31080; bugfix + on 0.4.1.1-alpha. + + o Minor bugfixes (memory leaks): + - Fix a trivial memory leak when parsing an invalid value from a + download schedule in the configuration. Fixes bug 30894; bugfix + on 0.3.4.1-alpha. + + o Code simplification and refactoring: + - Remove some dead code from circpad_machine_remove_token() to fix + some Coverity warnings (CID 1447298). Fixes bug 31027; bugfix + on 0.4.1.1-alpha. + + +Changes in version 0.4.1.3-alpha - 2019-06-25 + Tor 0.4.1.3-alpha resolves numerous bugs left over from the previous + alpha, most of them from earlier release series. + + o Major bugfixes (Onion service reachability): + - Properly clean up the introduction point map when circuits change + purpose from onion service circuits to pathbias, measurement, or + other circuit types. This should fix some service-side instances + of introduction point failure. Fixes bug 29034; bugfix + on 0.3.2.1-alpha. + + o Minor features (geoip): + - Update geoip and geoip6 to the June 10 2019 Maxmind GeoLite2 + Country database. Closes ticket 30852. + + o Minor features (logging): + - Give a more useful assertion failure message if we think we have + minherit() but we fail to make a region non-inheritable. Give a + compile-time warning if our support for minherit() is incomplete. + Closes ticket 30686. + + o Minor bugfixes (circuit isolation): + - Fix a logic error that prevented the SessionGroup sub-option from + being accepted. Fixes bug 22619; bugfix on 0.2.7.2-alpha. + + o Minor bugfixes (continuous integration): + - Allow the test-stem job to fail in Travis, because it sometimes + hangs. Fixes bug 30744; bugfix on 0.3.5.4-alpha. + - Skip test_rebind on macOS in Travis, because it is unreliable on + macOS on Travis. Fixes bug 30713; bugfix on 0.3.5.1-alpha. + - Skip test_rebind when the TOR_SKIP_TEST_REBIND environment + variable is set. Fixes bug 30713; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (directory authorities): + - Stop crashing after parsing an unknown descriptor purpose + annotation. We think this bug can only be triggered by modifying a + local file. Fixes bug 30781; bugfix on 0.2.0.8-alpha. + + o Minor bugfixes (pluggable transports): + - When running as a bridge with pluggable transports, always publish + pluggable transport information in our extrainfo descriptor, even + if ExtraInfoStatistics is 0. This information is needed by + BridgeDB. Fixes bug 30956; bugfix on 0.4.1.1-alpha. + + o Documentation: + - Mention URLs for Travis/Appveyor/Jenkins in ReleasingTor.md. + Closes ticket 30630. + + Changes in version 0.4.1.2-alpha - 2019-06-06 Tor 0.4.1.2-alpha resolves numerous bugs--some of them from the previous alpha, and some much older.
