Changes in version - 2020-09-15
Tor is the first stable release in the 0.4.4.x series. This
series improves our guard selection algorithms, adds v3 onion balance
support, improves the amount of code that can be disabled when running
without relay support, and includes numerous small bugfixes and
enhancements. It also lays the ground for some IPv6 features that
we'll be developing more in the next (0.4.5) series.
Per our support policy, we support each stable release series for nine
months after its first stable release, or three months after the first
stable release of the next series: whichever is longer. This means
that 0.4.4.x will be supported until around June 2021--or later, if
0.4.5.x is later than anticipated.
Note also that support for 0.4.2.x has just ended; support for 0.4.3
will continue until Feb 15, 2021. We still plan to continue supporting
0.3.5.x, our long-term stable series, until Feb 2022.
Below are the changes since For a complete list of changes

o Major bugfixes (onion services, DoS):
- Correct handling of parameters for the onion service DoS defense.
Previously, the consensus parameters for the onion service DoS
defenses were overwriting the parameters set by the service
operator using HiddenServiceEnableIntroDoSDefense. Fixes bug
40109; bugfix on
o Major bugfixes (stats, onion services):
- Fix a bug where we were undercounting the Tor network's total
onion service traffic, by ignoring any traffic originating from
clients. Now we count traffic from both clients and services.
Fixes bug 40117; bugfix on
o Minor features (control port):
- If a ClientName was specified in ONION_CLIENT_AUTH_ADD for an
onion service, display it when we use ONION_CLIENT_AUTH_VIEW.
Closes ticket 40089. Patch by Neel Chauhan.
o Minor features (denial-of-service memory limiter):
- Allow the user to configure even lower values for the
MaxMemInQueues parameter. Relays now enforce a minimum of 64 MB,
when previously the minimum was 256 MB. On clients, there is no
minimum. Relays and clients will both warn if the value is set so
low that Tor is likely to stop working. Closes ticket 24308.
o Minor features (tests):
- 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 bugfixes (guard selection algorithm):
- Avoid needless guard-related warning when upgrading from 0.4.3 to
0.4.4. Fixes bug 40105; bugfix on
o Minor bugfixes (tests):
- 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
