Hello, there's a new release candidate out for 0.4.5.4-rc. You can
get it at the usual place at https://dist.torproject.org/
We hope we're almost out of bugs; we're currently planning to do
somewhere between zero and one more release candidates before this
release series is finally stable.
As usual, you can find more about our planned release schedule at
https://gitlab.torproject.org/tpo/core/team/-/wikis/NetworkTeam/CoreTorRele…
Here's what's new:
Changes in version 0.4.5.4-rc - 2021-01-22
Tor 0.4.5.4-rc is the second release candidate in its series. It fixes
several bugs present in previous releases.
We expect that the stable release will be the same, or almost the
same, as this releasee candidate, unless serious bugs are found.
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
operators reported Tor using 100% CPU, while we investigate better
solutions. Fixes bug 24857; bugfix on 0.3.1.1-alpha.
o Minor feature (build system):
- New "make lsp" command to generate the compile_commands.json file
used by the ccls language server. The "bear" program is needed for
this. Closes ticket 40227.
o Minor features (authority, logging):
- Log more information for directory authority operators during the
consensus voting process, and while processing relay descriptors.
Closes ticket 40245.
- 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;
bugfix on 0.4.5.1-alpha.
Hello!
Tor 0.4.5.3-rc is now available for download at
https://dist.torproject.org/ . Official announcements will follow
once the website has updated.
Here's the changelog.
Changes in version 0.4.5.3-rc - 2021-01-12
Tor 0.4.5.3-rc is the first release candidate in its series. It fixes
several bugs, including one that broke onion services on certain older
ARM CPUs.
Though we anticipate that we'll be doing a bit more clean-up between
now and the stable release, we expect that our remaining changes will
be fairly simple. There will be at least one more release candidate
before 0.4.5.x is stable.
o Major bugfixes (onion service v3):
- Stop requiring a live consensus for v3 clients and services, and
allow a "reasonably live" consensus instead. This allows v3 onion
services to work even if the authorities fail to generate a
consensus for more than 2 hours in a row. Fixes bug 40237; bugfix
on 0.3.5.1-alpha.
o Minor features (crypto):
- Fix undefined behavior on our Keccak library. The bug only
appeared on platforms with 32-byte CPU cache lines (e.g. armv5tel)
and would result in wrong digests. Fixes bug 40210; bugfix on
0.2.8.1-alpha. Thanks to Bernhard Übelacker, Arnd Bergmann and
weasel for diagnosing this.
o Minor features (documentation):
- Mention the "!badexit" directive that can appear in an authority's
approved-routers file, and update the description of the
"!invalid" directive. Closes ticket 40188.
o Minor bugfixes (compilation):
- Fix a compilation warning about unreachable fallthrough
annotations when building with "--enable-all-bugs-are-fatal" on
some compilers. Fixes bug 40241; bugfix on 0.3.5.4-alpha.
- Fix the "--enable-static-tor" switch to properly set the "-static"
compile option onto the tor binary only. Fixes bug 40111; bugfix
on 0.2.3.1-alpha.
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
on 0.4.5.1-alpha.
- When a launching bandwidth testing circuit, don't incorrectly call
it a reachability test, or trigger a "CHECKING_REACHABILITY"
control event. Fixes bug 40205; bugfix on 0.4.5.1-alpha.
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
on 0.4.5.1-alpha.
o Minor bugfixes (SOCKS5):
- Handle partial SOCKS5 messages correctly. Previously, our code
would send an incorrect error message if it got a SOCKS5 request
that wasn't complete. Fixes bug 40190; bugfix on 0.3.5.1-alpha.
