+Changes in version 0.4.3.7 - 2020-11-12
+ Tor 0.4.3.7 backports several bugfixes from later releases. It
+ includes a fix for TROVE-2020-005, a security issue that could be
+ used, under certain cases, by an adversary to observe traffic patterns
+ on a limited number of circuits intended for a different relay.
+
+ Please be aware that support for the 0.4.3.x series will end on 15
+ January 2020. Please upgrade to 0.4.4.x or 0.4.5.x before then, or
+ downgrade to 0.3.5.x, which will be supported until at least 1
+ February 2022.
+
+ o Major features (fallback directory list, backport form 0.4.4.3-alpha):
+ - Replace the 148 fallback directories originally included in Tor
+ 0.4.1.4-rc (of which around 105 are still functional) with a list
+ of 144 fallbacks generated in July 2020. Closes ticket 40061.
+
+ o Major bugfixes (security, backport from 0.4.5.1-alpha):
+ - When completing a channel, relays now check more thoroughly to
+ make sure that it matches any pending circuits before attaching
+ those circuits. Previously, address correctness and Ed25519
+ identities were not checked in this case, but only when extending
+ circuits on an existing channel. Fixes bug 40080; bugfix on
+ 0.2.7.2-alpha. Resolves TROVE-2020-005.
+
+ o Major bugfixes (NSS, backport from 0.4.4.3-alpha):
+ - When running with NSS enabled, make sure that NSS knows to expect
+ nonblocking sockets. Previously, we set our TCP sockets as
+ nonblocking, but did not tell NSS, which in turn could lead to
+ unexpected blocking behavior. Fixes bug 40035; bugfix
+ on 0.3.5.1-alpha.
+
+ o Minor features (security, backport from 0.4.4.4-rc):
+ - Channels using obsolete versions of the Tor link protocol are no
+ longer allowed to circumvent address-canonicity checks. (This is
+ only a minor issue, since such channels have no way to set ed25519
+ keys, and therefore should always be rejected for circuits that
+ specify ed25519 identities.) Closes ticket 40081.
+
+ o Minor features (subprotocol versions, backport from 0.4.5.1-alpha):
+ - Tor no longer allows subprotocol versions larger than 63.
+ Previously version numbers up to UINT32_MAX were allowed, which
+ significantly complicated our code. Implements proposal 318;
+ closes ticket 40133.
+
+ o Minor features (tests, backport from 0.4.4.5):
+ - Our "make check" target now runs the unit tests in 8 parallel
+ chunks. Doing this speeds up hardened CI builds by more than a
+ factor of two. Closes ticket 40098.
+
+ o Minor features (tests, v2 onion services, backport from 0.4.5.1-alpha):
+ - Fix a rendezvous cache unit test that was triggering an underflow
+ on the global rend cache allocation. Fixes bug 40125; bugfix
+ on 0.2.8.1-alpha.
+ - Fix another rendezvous cache unit test that was triggering an
+ underflow on the global rend cache allocation. Fixes bug 40126;
+ bugfix on 0.2.8.1-alpha.
+
+ o Minor bugfixes (correctness, buffers, backport from 0.4.4.4-rc):
+ - Fix a correctness bug that could cause an assertion failure if we
+ ever tried using the buf_move_all() function with an empty input
+ buffer. As far as we know, no released versions of Tor do this.
+ Fixes bug 40076; bugfix on 0.3.3.1-alpha.
+
+ o Minor bugfixes (logging, backport from 0.4.5.1-alpha):
+ - Remove a debug logging statement that uselessly spammed the logs.
+ Fixes bug 40135; bugfix on 0.3.5.0-alpha.
+
+ o Minor bugfixes (rate limiting, bridges, pluggable transports, backport from 0.4.4.4-rc):
+ - On a bridge, treat all connections from an ExtORPort as remote by
+ default for the purposes of rate-limiting. Previously, bridges
+ would treat the connection as local unless they explicitly
+ received a "USERADDR" command. ExtORPort connections still count
+ as local if there is a USERADDR command with an explicit local
+ address. Fixes bug 33747; bugfix on 0.2.5.1-alpha.
+
+ o Minor bugfixes (relay configuration, crash, backport from 0.4.5.1-alpha):
+ - Avoid a fatal assert() when failing to create a listener
+ connection for an address that was in use. Fixes bug 40073; bugfix
+ on 0.3.5.1-alpha.
+
+ o Minor bugfixes (relay, usability, backport from 0.4.4.3-alpha):
+ - Adjust the rules for when to warn about having too many
+ connections to other relays. Previously we'd tolerate up to 1.5
+ connections per relay on average. Now we tolerate more connections
+ for directory authorities, and raise the number of total
+ connections we need to see before we warn. Fixes bug 33880; bugfix
+ on 0.3.1.1-alpha.
+
+ o Minor bugfixes (tests, 0.4.4.5):
+ - Fix the behavior of the rend_cache/clean_v2_descs_as_dir when run
+ on its own. Previously, it would exit with an error. Fixes bug
+ 40099; bugfix on 0.2.8.1-alpha.
+
+ o Minor bugfixes (v2 onion services, backport from 0.4.5.1-alpha):
+ - For HSFETCH commands on v2 onion services addresses, check the
+ length of bytes decoded, not the base32 length. Fixes bug 34400;
+ bugfix on 0.4.1.1-alpha. Patch by Neel Chauhan.
+
+ o Minor bugfixes (windows, backport from 0.4.4.4-rc):
+ - Fix a bug that prevented Tor from starting if its log file grew
+ above 2GB. Fixes bug 31036; bugfix on 0.2.1.8-alpha.
+
+ o Deprecated features (onion service v2, backport form 0.4.4.2-alpha):
+ - Add a deprecation warning for version 2 onion services. Closes
+ ticket 40003.
+
+ o Removed features (backport from 0.4.4.3-alpha):
+ - Our "check-local" test target no longer tries to use the
+ Coccinelle semantic patching tool parse all the C files. While it
+ is a good idea to try to make sure Coccinelle works on our C
+ before we run a Coccinelle patch, doing so on every test run has
+ proven to be disruptive. You can still run this tool manually with
+ "make check-cocci". Closes ticket 40030. ticket 40030.
