Closes + ticket 32622. + + o Minor features (directory authority): + - Authorities now recommend the protocol versions that are supported + by Tor 0.3.5 and later. (Earlier versions of Tor have been + deprecated since January of this year.) This recommendation will + cause older clients and relays to give a warning on startup, or + when they download a consensus directory. Closes ticket 32696. + + o Minor features (entry guards): + - Reinstate support for GUARD NEW/UP/DOWN control port events. + Closes ticket 40001. + + o Minor features (linux seccomp2 sandbox, portability): + - Allow Tor to build on platforms where it doesn't know how to + report which syscall caused the linux seccomp2 sandbox to fail. + This change should make the sandbox code more portable to less + common Linux architectures. Closes ticket 34382. + - Permit the unlinkat() syscall, which some Libc implementations use + to implement unlink(). Closes ticket 33346. + + o Minor bugfix (CI, Windows): + - Use the correct 64-bit printf format when compiling with MINGW on + Appveyor. Fixes bug 40026; bugfix on 0.3.5.5-alpha. + + o Minor bugfix (onion service v3 client): + - Remove a BUG() warning that could occur naturally. Fixes bug + 34087; bugfix on 0.3.2.1-alpha. + + o Minor bugfix (SOCKS, onion service client): + - Detect v3 onion service addresses of the wrong length when + returning the F6 ExtendedErrors code. Fixes bug 33873; bugfix + on 0.4.3.1-alpha. + + o Minor bugfixes (compiler warnings): + - Fix a compiler warning on platforms with 32-bit time_t values. + Fixes bug 40028; bugfix on 0.3.2.8-rc. + + o Minor bugfixes (control port, onion service): + - Consistently use 'address' in "Invalid v3 address" response to + ONION_CLIENT_AUTH commands. Previously, we would sometimes say + 'addr'. Fixes bug 40005; bugfix on 0.4.3.1-alpha. + + o Minor bugfixes (logging): + - Downgrade a noisy log message that could occur naturally when + receiving an extrainfo document that we no longer want. Fixes bug + 16016; bugfix on 0.2.6.3-alpha. + + o Minor bugfixes (onion services v3): + - Avoid a non-fatal assertion failure in certain edge-cases when + opening an intro circuit as a client. Fixes bug 34084; bugfix + on 0.3.2.1-alpha. + + o Deprecated features (onion service v2): + - Add a deprecation warning for version 2 onion services. Closes + ticket 40003. + + o Removed features (IPv6, revert): + - Revert the change in the default value of ClientPreferIPv6OrPort: + it breaks the torsocks use case. The SOCKS resolve command has no + mechanism to ask for a specific address family (v4 or v6), and so + prioritizing IPv6 when an IPv4 address is requested on the SOCKS + interface resulted in a failure.

If you want to see more detailed descriptions of the changes in each development snapshot, see the ChangeLog file. +Changes in version 0.3.5.11 - 2020-07-09 + Tor 0.3.5.11 backports fixes from later tor releases, including several + usability, portability, and reliability fixes. + + This release also fixes TROVE-2020-001, a medium-severity denial of + service vulnerability affecting all versions of Tor when compiled with + the NSS encryption library. (This is not the default configuration.) + Using this vulnerability, an attacker could cause an affected Tor + instance to crash remotely. This issue is also tracked as CVE-2020- + 15572.

Fixes bug 33119; bugfix on + 0.3.5.1-alpha. This issue is also tracked as TROVE-2020-001 + and CVE-2020-15572. + + o Major bugfixes (DoS defenses, bridges, pluggable transport, backport from 0.4.3.4-rc): + - Fix a bug that was preventing DoS defenses from running on bridges + with a pluggable transport. Previously, the DoS subsystem was not + given the transport name of the client connection, thus failed to + find the GeoIP cache entry for that client address. Fixes bug + 33491; bugfix on 0.3.3.2-alpha. + + o Minor features (testing, backport from 0.4.3.4-rc): + - The unit tests now support a "TOR_SKIP_TESTCASES" environment + variable to specify a list of space-separated test cases that + should not be executed. We will use this to disable certain tests + that are failing on Appveyor because of mismatched OpenSSL + libraries. Part of ticket 33643. + + o Minor bugfix (CI, Windows, backport from 0.4.4.2-alpha): + - Use the correct 64-bit printf format when compiling with MINGW on + Appveyor.

Fixes bug 33361; bugfix + on 0.1.1.10-alpha. + + o Minor bugfixes (client performance, backport from 0.4.4.1-alpha): + - Resume use of preemptively-built circuits when UseEntryGuards is set + to 0.

Fixes bug 34303; bugfix + on 0.3.3.2-alpha. + + o Minor bugfixes (compiler compatibility, backport from 0.4.3.5): + - Avoid compiler warnings from Clang 10 related to the use of GCC- + style "/* falls through */" comments.

Fixes bug 32884; bugfix + on 0.3.3.1-alpha. + + o Minor bugfixes (key portability, backport from 0.4.3.4-rc): + - When reading PEM-encoded key data, tolerate CRLF line-endings even + if we are not running on Windows.
