o Major bugfixes (IPv6, relay):
- Fix a bug that prevented a relay from publishing its descriptor if
an auto-discovered IPv6 that was found unreachable. Fixes bug
40279; bugfix on 0.4.5.1-alpha.
o Minor features (protocol versions):
- Stop claiming to support the "DirCache=1" subprotocol version.
Technically, we stopped supporting this subprotocol back in
0.4.5.1-alpha, but we needed to wait for the authorities to stop
listing it as "required" before we could drop it from the list.
Closes ticket 40221.

the current release. Fixes bug 40281; bugfix on 0.4.0.1-alpha.
o Minor bugfixes (metrics port):
- Fix a bug warning when a metrics port socket was unexpectedly
closed. Fixes bug 40257; bugfix on 0.4.5.1-alpha
o Minor bugfixes (relay):
- Allow relays to have a RFC1918 address if PublishServerDescriptor
is set to 0 and AssumeReachable is set to 1. This is to support
the use case of a bridge on a local network, exposed via a
pluggable transport. Fixes bug 40208; bugfix on 0.4.5.1-alpha.
o Minor bugfixes (relay, config):
- Fix a problem in the removal of duplicate ORPorts from the
internal port list when loading the config file. We were removing
the wrong ports, breaking valid torrc uses cases for multiple
ORPorts of the same address family. Fixes bug 40289; bugfix
on 0.4.5.1-alpha.
o Major feature (exit):
- Re-entry into the network is now denied at the Exit level to all
relays' ORPorts and authorities' ORPorts and DirPorts. This change
should help mitgate a set of denial-of-service attacks. Closes
ticket 2667.
o Minor bugfixes (relay, configuration):
- Don't attempt to discover our address (IPv4 or IPv6) if no ORPort
for it can be found in the configuration. Fixes bug 40254; bugfix
on 0.4.5.1-alpha.
o Major bugfixes (authority, IPv6):
- Do not consider multiple relays in the same IPv6 /64 network to be
sybils. Fixes bug 40243; bugfix on 0.4.5.1-alpha.
o Major bugfixes (directory cache, performance, windows):
- Limit the number of items in the consensus diff cache to 64 on
Windows. We hope this will mitigate an issue where Windows relay

- Reject obsolete router/extrainfo descriptors earlier and more
quietly, to avoid spamming the logs. Fixes bug 40238; bugfix
on 0.4.5.1-alpha.
o Minor bugfixes (compilation):
- Fix another warning about unreachable fallthrough annotations when
building with "--enable-all-bugs-are-fatal" on some compilers.
Fixes bug 40241; bugfix on 0.4.5.3-rc.
- Change the linker flag ordering in our library search code so that
it works for compilers that need the libraries to be listed in the
right order. Fixes bug 33624; bugfix on 0.1.1.0-alpha.
o Minor bugfixes (config, bridge):
- Don't initiate a connection to a bridge configured to use a
missing transport. This change reverts an earlier fix that would
try to avoid such situations during configuration chcecking, but
which doesn't work with DisableNetwork. Fixes bug 40106; bugfix
on 0.4.5.1-alpha.
o Minor bugfixes (onion services):
- Avoid a non-fatal assertion in certain edge-cases when
establishing a circuit to an onion service. Fixes bug 32666;
bugfix on 0.3.0.3-alpha.
o Minor bugfixes (relay):
- If we were unable to build our descriptor, don't mark it as having
been advertised. Also remove an harmless BUG(). Fixes bug 40231;

o Minor bugfixes (config, bridge):
- Really fix the case where torrc has a missing ClientTransportPlugin
but is configured with a Bridge line and UseBridges. Previously,
we didn't look at the managed proxy list and thus would fail for
the "exec" case. Fixes bug 40106; bugfix on 0.4.5.1-alpha.
o Minor bugfixes (logging, relay):
- Log our address as reported by the directory authorities, if none
was configured or detected before. Fixes bug 40201; bugfix

- When a launching bandwidth testing circuit, don't incorrectly call
it a reachability test, or trigger a "CHECKING_REACHABILITY"

o Minor bugfixes (relay, statistics):
- Report the correct connection statistics in our extrainfo
documents. Previously there was a problem in the file loading
function which would wrongly truncate a state file, causing the
wrong information to be reported. Fixes bug 40226; bugfix

o Minor bugfixes (compilation):
- Use the correct 'ranlib' program when building libtor.a.

Changes in version 0.4.5.1-alpha - 2020-11-01
Tor 0.4.5.1-alpha is the first alpha release in the 0.4.5.x series. It
improves support for IPv6, address discovery and self-testing, code
metrics and tracing.
This release also fixes 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. To
mount this attack, the adversary would need to actively extend
circuits to an incorrect address, as well as compromise a relay's
legacy RSA-1024 key. We'll be backporting this fix to other release
series soon, after it has had some testing.
Here are the changes since 0.4.4.5.
