Hi!
There's a new release candidate available for download at the usual
place on https://dist.torproject.org. The version is 0.4.6.4-rc.
This is probably the last release candidate before 0.4.6.x is stable,
so please test it if you can!
Official announcements will follow after the website updates. Here's
the changelog:
Changes in version 0.4.6.4-rc - 2021-05-28
Tor 0.4.6.4-rc fixes a few bugs from previous releases. This, we hope,
the final release candidate in its series: unless major new issues are
found, the next release will be stable.
o Minor features (compatibility):
- Remove an assertion function related to TLS renegotiation. It was
used nowhere outside the unit tests, and it was breaking
compilation with recent alpha releases of OpenSSL 3.0.0. Closes
ticket 40399.
o Minor bugfixes (consensus handling):
- Avoid a set of bugs that could be caused by inconsistently
preferring an out-of-date consensus stored in a stale directory
cache over a more recent one stored on disk as the latest
consensus. Fixes bug 40375; bugfix on 0.3.1.1-alpha.
o Minor bugfixes (control, sandbox):
- Allow the control command SAVECONF to succeed when the seccomp
sandbox is enabled, and make SAVECONF keep only one backup file to
simplify implementation. Previously SAVECONF allowed a large
number of backup files, which made it incompatible with the
sandbox. Fixes bug 40317; bugfix on 0.2.5.4-alpha. Patch by
Daniel Pinto.
o Minor bugfixes (metrics port):
- Fix a bug that made tor try to re-bind() on an already open
MetricsPort every 60 seconds. Fixes bug 40370; bugfix
on 0.4.5.1-alpha.
o Removed features:
- Remove unneeded code for parsing private keys in directory
documents. This code was only used for client authentication in v2
onion services, which are now unsupported. Closes ticket 40374.
Hi, all!
There's a new stable release (0.4.5.8) and a new release candidate
forr the upcoming series (0.4.6.3-rc) available for download at
https://dist.torproject.org/ . I'll send out official announcements
later today.
If you can, please remember to try out alpha releases on your
platform, especially if you're building for something besides Linux,
Windows, or OSX: it really helps us to know about bugs before the
releases are stable. Please report issues at
https://bugs.torproject.org/ so we aren't reliant on my inbox
management skills. :)
Here are the changelogs:
Changes in version 0.4.6.3-rc - 2021-05-10
Tor 0.4.6.3-rc is the first release candidate in its series. It fixes
a few small bugs from previous versions, and adds a better error
message when trying to use (no longer supported) v2 onion services.
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 likely be at least one more release
candidate before 0.4.6.x is stable.
o Major bugfixes (onion service, control port):
- Make the ADD_ONION command properly configure client authorization.
Before this fix, the created onion failed to add the client(s).
Fixes bug 40378; bugfix on 0.4.6.1-alpha.
o Minor features (compatibility, Linux seccomp sandbox):
- Add a workaround to enable the Linux sandbox to work correctly
with Glibc 2.33. This version of Glibc has started using the
fstatat() system call, which previously our sandbox did not allow.
Closes ticket 40382; see the ticket for a discussion of trade-offs.
o Minor features (compilation):
- Make the autoconf script build correctly with autoconf versions
2.70 and later. Closes part of ticket 40335.
o Minor features (geoip data):
- Update the geoip files to match the IPFire Location Database, as
retrieved on 2021/05/07.
o Minor features (onion services):
- Add a warning message when trying to connect to (no longer
supported) v2 onion services. Closes ticket 40373.
o Minor bugfixes (build, cross-compilation):
- Allow a custom "ar" for cross-compilation. Our previous build
script had used the $AR environment variable in most places, but
it missed one. Fixes bug 40369; bugfix on 0.4.5.1-alpha.
o Minor bugfixes (compiler warnings):
- Fix an indentation problem that led to a warning from GCC 11.1.1.
Fixes bug 40380; bugfix on 0.3.0.1-alpha.
o Minor bugfixes (logging, relay):
- Emit a warning if an Address is found to be internal and tor can't
use it. Fixes bug 40290; bugfix on 0.4.5.1-alpha.
o Minor bugfixes (onion service, client, memory leak):
- Fix a bug where an expired cached descriptor could get overwritten
with a new one without freeing it, leading to a memory leak. Fixes
bug 40356; bugfix on 0.3.5.1-alpha.
Changes in version 0.4.5.8 - 2021-05-10
Tor 0.4.5.8 fixes several bugs in earlier version, backporting fixes
from the 0.4.6.x series.
o Minor features (compatibility, Linux seccomp sandbox, backport
from 0.4.6.3-rc):
- Add a workaround to enable the Linux sandbox to work correctly
with Glibc 2.33. This version of Glibc has started using the
fstatat() system call, which previously our sandbox did not allow.
Closes ticket 40382; see the ticket for a discussion of trade-offs.
o Minor features (compilation, backport from 0.4.6.3-rc):
- Make the autoconf script build correctly with autoconf versions
2.70 and later. Closes part of ticket 40335.
o Minor features (fallback directory list, backport from 0.4.6.2-alpha):
- Regenerate the list of fallback directories to contain a new set
of 200 relays. Closes ticket 40265.
o Minor features (geoip data):
- Update the geoip files to match the IPFire Location Database, as
retrieved on 2021/05/07.
o Minor features (onion services):
- Add warning message when connecting to now deprecated v2 onion
services. As announced, Tor 0.4.5.x is the last series that will
support v2 onions. Closes ticket 40373.
o Minor bugfixes (bridge, pluggable transport, backport from 0.4.6.2-alpha):
- Fix a regression that made it impossible start Tor using a bridge
line with a transport name and no fingerprint. Fixes bug 40360;
bugfix on 0.4.5.4-rc.
o Minor bugfixes (build, cross-compilation, backport from 0.4.6.3-rc):
- Allow a custom "ar" for cross-compilation. Our previous build
script had used the $AR environment variable in most places, but
it missed one. Fixes bug 40369; bugfix on 0.4.5.1-alpha.
o Minor bugfixes (channel, DoS, backport from 0.4.6.2-alpha):
- Fix a non-fatal BUG() message due to a too-early free of a string,
when listing a client connection from the DoS defenses subsystem.
Fixes bug 40345; bugfix on 0.4.3.4-rc.
o Minor bugfixes (compiler warnings, backport from 0.4.6.3-rc):
- Fix an indentation problem that led to a warning from GCC 11.1.1.
Fixes bug 40380; bugfix on 0.3.0.1-alpha.
o Minor bugfixes (controller, backport from 0.4.6.1-alpha):
- Fix a "BUG" warning that would appear when a controller chooses
the first hop for a circuit, and that circuit completes. Fixes bug
40285; bugfix on 0.3.2.1-alpha.
o Minor bugfixes (onion service, client, memory leak, backport from
0.4.6.3-rc):
- Fix a bug where an expired cached descriptor could get overwritten
with a new one without freeing it, leading to a memory leak. Fixes
bug 40356; bugfix on 0.3.5.1-alpha.
o Minor bugfixes (testing, BSD, backport from 0.4.6.2-alpha):
- Fix pattern-matching errors when patterns expand to invalid paths
on BSD systems. Fixes bug 40318; bugfix on 0.4.5.1-alpha. Patch by
Daniel Pinto.
