+Changes in version 0.4.5.2-alpha - 2020-11-23
+ Tor 0.4.5.2-alpha is the second alpha release in the 0.4.5.x series.
+ It fixes several bugs present in earlier releases, including one that
+ made it impractical to run relays on Windows. It also adds a few small
+ safety features to improve Tor's behavior in the presence of strange
+ compile-time options, misbehaving proxies, and future versions
+ of OpenSSL.
+
+ o Major bugfixes (relay, windows):
+ - Fix a bug in our implementation of condition variables on Windows.
+ Previously, a relay on Windows would use 100% CPU after running
+ for some time. Because of this change, Tor now require Windows
+ Vista or later to build and run. Fixes bug 30187; bugfix on
+ 0.2.6.3-alpha. (This bug became more serious in 0.3.1.1-alpha with
+ the introduction of consensus diffs.) Patch by Daniel Pinto.
+
+ o Minor features (compilation):
+ - Disable deprecation warnings when building with OpenSSL 3.0.0 or
+ later. There are a number of APIs newly deprecated in OpenSSL
+ 3.0.0 that Tor still requires. (A later version of Tor will try to
+ stop depending on these APIs.) Closes ticket 40165.
+
+ o Minor features (protocol, proxy support, defense in depth):
+ - Respond more deliberately to misbehaving proxies that leave
+ leftover data on their connections, so as to make Tor even less
+ likely to allow the proxies to pass their data off as having come
+ from a relay. Closes ticket 40017.
+
+ o Minor features (safety):
+ - Log a warning at startup if Tor is built with compile-time options
+ that are likely to make it less stable or reliable. Closes
+ ticket 18888.
+
+ o Minor bugfixes (circuit, handshake):
+ - In the v3 handshaking code, use connection_or_change_state() to
+ change the state. Previously, we changed the state directly, but
+ this did not pass the state change to the pubsub or channel
+ objects, potentially leading to bugs. Fixes bug 32880; bugfix on
+ 0.2.3.6-alpha. Patch by Neel Chauhan.
+
+ o Minor bugfixes (compilation):
+ - Use the correct 'ranlib' program when building libtor.a.
+ Previously we used the default ranlib, which broke some kinds of
+ cross-compilation. Fixes bug 40172; bugfix on 0.4.5.1-alpha.
+ - Remove a duplicate typedef in metrics_store.c. Fixes bug 40177;
+ bugfix on 0.4.5.1-alpha.
+ - When USDT tracing is enabled, and STAP_PROBEV() is missing, don't
+ attempt to build. Linux supports that macro but not the BSDs.
+ Fixes bug 40174; bugfix on 0.4.5.1-alpha.
+
+ o Minor bugfixes (configuration):
+ - Exit Tor on a misconfiguration when the Bridge line is configured
+ to use a transport but no corresponding ClientTransportPlugin can
+ be found. Prior to this fix, Tor would attempt to connect to the
+ bridge directly without using the transport, making it easier for
+ adversaries to notice the bridge. Fixes bug 25528; bugfix
+ on 0.2.6.1-alpha.
+ - Fix an issue where an ORPort was compared with other kinds of
+ ports, when it should have been only checked against other
+ ORPorts. This bug would lead to "DirPort auto" getting ignored.
+ Fixes bug 40195; bugfix on 0.4.5.1-alpha.
+ - Fix a bug where a second non-ORPort with a variant family (ex:
+ SocksPort [::1]:9050) would be ignored due to a configuration
+ parsing error. Fixes bug 40183; bugfix on 0.4.5.1-alpha.
+
+ o Minor bugfixes (crash, relay, signing key):
+ - Avoid assertion failures when we run Tor from the command line
+ with `--key-expiration sign`, but an ORPort is not set. Fixes bug
+ 40015; bugfix on 0.3.2.1-alpha. Patch by Neel Chauhan.
+
+ o Minor bugfixes (logging):
+ - Remove trailing whitespace from control event log messages. Fixes
+ bug 32178; bugfix on 0.1.1.1-alpha. Based on a patch by
+ Amadeusz Pawlik.
+ - Turn warning-level log message about SENDME failure into a debug-
+ level message. (This event can happen naturally, and is no reason
+ for concern). Fixes bug 40142; bugfix on 0.4.1.1-alpha.
+
+ o Minor bugfixes (relay, address discovery):
+ - Don't trigger an IP change when no new valid IP can be found.
+ Fixes bug 40071; bugfix on 0.4.5.1-alpha.
+ - When attempting to discover our IP, use a simple test circuit,
+ rather than a descriptor fetch: the same address information is
+ present in NETINFO cells, and is better authenticated there. Fixes
+ bug 40071; bugfix on 0.4.5.1-alpha.
+
+ o Minor bugfixes (testing):
+ - Fix the `config/parse_tcp_proxy_line` test so that it works
+ correctly on systems where the DNS provider hijacks invalid
+ queries. Fixes part of bug 40179; bugfix on 0.4.3.1-alpha.
+ - Fix unit tests that used newly generated list of routers so that
+ they check them with respect to the date when they were generated,
+ not with respect to the current time. Fixes bug 40187; bugfix
+ on 0.4.5.1-alpha.
+ - Fix our Python reference-implementation for the v3 onion service
+ handshake so that it works correctly with the version of hashlib
+ provided by Python 3.9. Fixes part of bug 40179; bugfix
+ on 0.3.1.6-rc.
+ - Fix the `tortls/openssl/log_one_error` test to work with OpenSSL
+ 3.0.0. Fixes bug 40170; bugfix on 0.2.8.1-alpha.
+
+ o Removed features (controller):
+ - Remove the "GETINFO network-status" controller command. It has
+ been deprecated since 0.3.1.1-alpha. Closes ticket 22473.
