If no serious bugs are found in this version, the + next version will be a release candidate. + + This release also marks the end of support for the Tor 0.2.4.x, + 0.2.6.x, and 0.2.7.x release series. Those releases will receive no + further bug or security fixes. Anyone still running or distributing + one of those versions should upgrade. + + o Major features (build system, continuous integration): + - Tor's repository now includes a Travis Continuous Integration (CI) + configuration file (.travis.yml). This is meant to help new + developers and contributors who fork Tor to a Github repository be + better able to test their changes, and understand what we expect + to pass. To use this new build feature, you must fork Tor to your + Github account, then go into the "Integrations" menu in the + repository settings for your fork and enable Travis, then push + your changes. Closes ticket 22636. + + o Major bugfixes (openbsd, denial-of-service): + - Avoid an assertion failure bug affecting our implementation of + inet_pton(AF_INET6) on certain OpenBSD systems whose strtol() + handling of "0xfoo" differs from what we had expected. Fixes bug + 22789; bugfix on 0.2.3.8-alpha. Also tracked as TROVE-2017-007. + + o Major bugfixes (relay, performance): + - Perform circuit handshake operations at a higher priority than we + use for consensus diff creation and compression. This should + prevent circuits from starving when a relay or bridge receives a + new consensus, especially on lower-powered machines. Fixes bug + 22883; bugfix on 0.3.1.1-alpha. + + o Minor features (bridge authority): + - Add "fingerprint" lines to the networkstatus-bridges file produced + by bridge authorities. Closes ticket 22207. + + o Minor features (directory cache, consensus diff): + - Add a new MaxConsensusAgeForDiffs option to allow directory cache + operators with low-resource environments to adjust the number of + consensuses they'll store and generate diffs from. Most cache + operators should leave it unchanged. Helps to work around + bug 22883. + + o Minor features (geoip): + - Update geoip and geoip6 to the July 4 2017 Maxmind GeoLite2 + Country database. + + o Minor features (relay, performance): + - Always start relays with at least two worker threads, to prevent + priority inversion on slow tasks. Part of the fix for bug 22883. + - Allow background work to be queued with different priorities, so + that a big pile of slow low-priority jobs will not starve out + higher priority jobs. This lays the groundwork for a fix for + bug 22883. + + o Minor bugfixes (build system, rust): + - Fix a problem where Rust toolchains were not being found when + building without --enable-cargo-online-mode, due to setting the + $HOME environment variable instead of $CARGO_HOME. Fixes bug + 22830; bugfix on 0.3.1.1-alpha. Fix by Chelsea Komlo. + + o Minor bugfixes (compatibility, zstd): + - Write zstd epilogues correctly when the epilogue requires + reallocation of the output buffer, even with zstd 1.3.0. + (Previously, we worked on 1.2.0 and failed with 1.3.0). Fixes bug + 22927; bugfix on 0.3.1.1-alpha. + + o Minor bugfixes (compilation warnings): + - Suppress -Wdouble-promotion warnings with clang 4.0. Fixes bug + 22915; bugfix on 0.2.8.1-alpha. + - Fix warnings when building with libscrypt and openssl scrypt + support on Clang. Fixes bug 22916; bugfix on 0.2.7.2-alpha. + - Compile correctly when both openssl 1.1.0 and libscrypt are + detected. Previously this would cause an error. Fixes bug 22892; + bugfix on 0.3.1.1-alpha. + - When building with certain versions of the mingw C header files, + avoid float-conversion warnings when calling the C functions + isfinite(), isnan(), and signbit(). Fixes bug 22801; bugfix + on 0.2.8.1-alpha. + + o Minor bugfixes (coverity build support): + - Avoid Coverity build warnings related to our BUG() macro. By + default, Coverity treats BUG() as the Linux kernel does: an + instant abort(). We need to override that so our BUG() macro + doesn't prevent Coverity from analyzing functions that use it. + Fixes bug 23030; bugfix on 0.2.9.1-alpha. + + o Minor bugfixes (directory authority): + - When a directory authority rejects a descriptor or extrainfo with + a given digest, mark that digest as undownloadable, so that we do + not attempt to download it again over and over. We previously + tried to avoid downloading such descriptors by other means, but we + didn't notice if we accidentally downloaded one anyway. This + behavior became problematic in 0.2.7.2-alpha, when authorities + began pinning Ed25519 keys. Fixes bug 22349; bugfix + on 0.2.1.19-alpha. + + o Minor bugfixes (error reporting, windows): + - When formatting Windows error messages, use the English format to + avoid codepage issues. Fixes bug 22520; bugfix on 0.1.2.8-alpha. + Patch from "Vort". + + o Minor bugfixes (file limits, osx): + - When setting the maximum number of connections allowed by the OS, + always allow some extra file descriptors for other files. Fixes + bug 22797; bugfix on 0.2.0.10-alpha. + + o Minor bugfixes (linux seccomp2 sandbox): + - Avoid a sandbox failure when trying to re-bind to a socket and + mark it as IPv6-only. Fixes bug 20247; bugfix on 0.2.5.1-alpha. + + o Minor bugfixes (memory leaks): + - Fix a small memory leak when validating a configuration that uses + two or more AF_UNIX sockets for the same port type. Fixes bug + 23053; bugfix on 0.2.6.3-alpha. This is CID 1415725. + + o Minor bugfixes (unit tests): + - test_consdiff_base64cmp would fail on OS X because while OS X + follows the standard of (less than zero/zero/greater than zero), + it doesn't follow the convention of (-1/0/+1). Make the test + comply with the standard. Fixes bug 22870; bugfix on 0.3.1.1-alpha. + - Fix a memory leak in the link-handshake/certs_ok_ed25519 test. + Fixes bug 22803; bugfix on 0.3.0.1-alpha. + + Changes in version 0.3.1.4-alpha - 2017-06-29 Tor 0.3.1.4-alpha fixes a path selection bug that would allow a client to use a guard that was in the same network family as a chosen exit
