+Changes in version 0.4.8.1-alpha - 2023-06-01
+ This is the first alpha of the 0.4.8.x series. Two major features in this
+ version which are Conflux and onion service Proof-of-Work (PoW). There are
+ also many small features in particular, worth noting, the MetricsPort is now
+ exporting more relay and onion service metrics. Finally, there are
+ also numerous minor bugfixes included in this version.
+
+ o Major features (onion service, proof-of-work):
+ - Implement proposal 327 (Proof-Of-Work). This is aimed at thwarting
+ introduction flooding DoS attacks by introducing a dynamic Proof-Of-Work
+ protocol that occurs over introduction circuits. This introduces several
+ torrc options prefixed with "HiddenServicePoW" in order to control this
+ feature. By default, this is disabled. Closes ticket 40634.
+
+ o Major features (conflux):
+ - Implement Proposal 329 (conflux traffic splitting). Conflux splits
+ traffic across two circuits to Exits that support the protocol.
+ These circuits are pre-built only, which means that if the pre-
+ built conflux pool runs out, regular circuits will then be used.
+ When using conflux circuit pairs, clients choose the lower-latency
+ circuit to send data to the Exit. When the Exit sends data to the
+ client, it maximizes throughput, by fully utilizing both circuits
+ in a multiplexed fashion. Alternatively, clients can request that
+ the Exit optimize for latency when transmitting to them, by
+ setting the torrc option 'ConfluxClientUX latency'. Onion services
+ are not currently supported, but will be in arti. Many other
+ future optimizations will also be possible using this protocol.
+ Closes ticket 40593.
+
+ o Major features (dirauth):
+ - Directory authorities and relays now interact properly with
+ directory authorities if they change addresses. In the past, they
+ would continue to upload votes, signatures, descriptors, etc to
+ the hard-coded address in the configuration. Now, if the directory
+ authority is listed in the consensus at a different address, they
+ will direct queries to this new address. Implements ticket 40705.
+
+ o Minor feature (CI):
+ - Update CI to use Debian Bullseye for runners.
+
+ o Minor feature (client, IPv6):
+ - Make client able to pick IPv6 relays by default now meaning
+ ClientUseIPv6 option now defaults to 1. Closes ticket 40785.
+
+ o Minor feature (compilation):
+ - Fix returning something other than "Unknown N/A" as libc version
+ if we build tor on an O.S. like DragonFlyBSD, FreeBSD, OpenBSD
+ or NetBSD.
+
+ o Minor feature (cpuworker):
+ - Always use the number of threads for our CPU worker pool to the
+ number of core available but cap it to a minimum of 2 in case of a
+ single core. Fixes bug 40713; bugfix on 0.3.5.1-alpha.
+
+ o Minor feature (lzma):
+ - Fix compiler warnings for liblzma >= 5.3.1. Closes ticket 40741.
+
+ o Minor feature (MetricsPort, relay):
+ - Expose time until online keys expires on the MetricsPort. Closes
+ ticket 40546.
+
+ o Minor feature (MetricsPort, relay, onion service):
+ - Add metrics for the relay side onion service interactions counting
+ seen cells. Closes ticket 40797. Patch by "friendly73".
+
+ o Minor features (directory authorities):
+ - Directory authorities now include their AuthDirMaxServersPerAddr
+ config option in the consensus parameter section of their vote.
+ Now external tools can better predict how they will behave.
+ Implements ticket 40753.
+
+ o Minor features (directory authority):
+ - Add a new consensus method in which the "published" times on
+ router entries in a microdesc consensus are all set to a
+ meaningless fixed date. Doing this will make the download size for
+ compressed microdesc consensus diffs much smaller. Part of ticket
+ 40130; implements proposal 275.
+
+ o Minor features (network documents):
+ - Clients and relays no longer track the "published on" time
+ declared for relays in any consensus documents. When reporting
+ this time on the control port, they instead report a fixed date in
+ the future. Part of ticket 40130.
+
+ o Minor features (fallbackdir):
+ - Regenerate fallback directories generated on June 01, 2023.
+
+ o Minor features (geoip data):
+ - Update the geoip files to match the IPFire Location Database, as
+ retrieved on 2023/06/01.
+
+ o Minor features (hs, metrics):
+ - Add tor_hs_rend_circ_build_time and tor_hs_intro_circ_build_time
+ histograms to measure hidden service rend/intro circuit build time
+ durations. Part of ticket 40757.
+
+ o Minor features (metrics):
+ - Add a `reason` label to the HS error metrics. Closes ticket 40758.
+ - Add service side metrics for REND and introduction request
+ failures. Closes ticket 40755.
+ - Add support for histograms. Part of ticket 40757.
+
+ o Minor features (pluggable transports):
+ - Automatically restart managed Pluggable Transport processes when
+ their process terminate. Resolves ticket 33669.
+
+ o Minor features (portability, compilation):
+ - Use OpenSSL 1.1 APIs for LibreSSL, fixing LibreSSL 3.5
+ compatibility. Fixes issue 40630; patch by Alex Xu (Hello71).
+
+ o Minor features (relay):
+ - Do not warn about configuration options that may expose a non-
+ anonymous onion service. Closes ticket 40691.
+
+ o Minor features (relays):
+ - Trigger OOS when bind fails with EADDRINUSE. This improves
+ fairness when a large number of exit connections are requested,
+ and properly signals exhaustion to the network. Fixes issue 40597;
+ patch by Alex Xu (Hello71).
+
+ o Minor features (tests):
+ - Avoid needless key reinitialization with OpenSSL during unit
+ tests, saving significant time. Patch from Alex Xu.
+
+ o Minor bugfix (relay, logging):
+ - The wrong max queue cell size was used in a protocol warning
+ logging statement. Fixes bug 40745; bugfix on 0.4.7.1-alpha.
+
+ o Minor bugfixes (logging):
+ - Avoid ""double-quoting"" strings in several log messages. Fixes
+ bug 22723; bugfix on 0.1.2.2-alpha.
+ - Correct a log message when cleaning microdescriptors. Fixes bug
+ 40619; bugfix on 0.2.5.4-alpha.
+
+ o Minor bugfixes (metrics):
+ - Decrement hs_intro_established_count on introduction circuit
+ close. Fixes bug 40751; bugfix on 0.4.7.12.
+
+ o Minor bugfixes (pluggable transports, windows):
+ - Remove a warning `BUG()` that could occur when attempting to
+ execute a non-existing pluggable transport on Windows. Fixes bug
+ 40596; bugfix on 0.4.0.1-alpha.
+
+ o Minor bugfixes (relay):
+ - Remove a "BUG" warning for an acceptable race between a circuit
+ close and considering that circuit active. Fixes bug 40647; bugfix
+ on 0.3.5.1-alpha.
+ - Remove a harmless "Bug" log message that can happen in
+ relay_addr_learn_from_dirauth() on relays during startup. Finishes
+ fixing bug 40231. Fixes bug 40523; bugfix on 0.4.5.4-rc.
+
+ o Minor bugfixes (sandbox):
+ - Allow membarrier for the sandbox. And allow rt_sigprocmask when
+ compiled with LTTng. Fixes bug 40799; bugfix on 0.3.5.1-alpha.
+ - Fix sandbox support on AArch64 systems. More "*at" variants of
+ syscalls are now supported. Signed 32 bit syscall parameters are
+ checked more precisely, which should lead to lower likelihood of
+ breakages with future compiler and libc releases. Fixes bug 40599;
+ bugfix on 0.4.4.3-alpha.
+
+ o Minor bugfixes (state file):
+ - Avoid a segfault if the state file doesn't contains TotalBuildTimes
+ along CircuitBuildAbandonedCount being above 0. Fixes bug 40437;
+ bugfix on 0.3.5.1-alpha.
+
+ o Removed features:
+ - Remove the RendPostPeriod option. This was primarily used in
+ Version 2 Onion Services and after its deprecation isn't needed
+ anymore. Closes ticket 40431. Patch by Neel Chauhan.

- fixing bug 40231. Fixes bug 40523; bugfix on 0.4.5.4-rc.
+++ /dev/null
- o Major bugfixes (relay):
- - When opening a channel because of a circuit request that did not
- include an Ed25519 identity, record the Ed25519 identity that we
- actually received, so that we can use the channel for other circuit
- requests that _do_ list an Ed25519 identity.
- (Previously we had code to record this identity, but a logic bug
- caused it to be disabled.) Fixes bug 40563; bugfix on 0.3.0.1-alpha.
- Patch from "cypherpunks".
+++ /dev/null
- o Minor bugfixes (logging):
- - Demote a harmless warn log message about finding a second hop to from
- warn level to info level, if we do not have enough descriptors yet.
- Leave it at notice level for other cases. Fixes bug 40603;
- bugfix on 0.4.7.1-alpha.
+++ /dev/null

- Fixes bug 40620; bugfix on 0.4.7.5-alpha.
+++ /dev/null
- o Major bugfixes (congestion control, TROVE-2022-001):
- - Fix a scenario where RTT estimation can become wedged, seriously
- degrading congestion control performance on all circuits. This impacts
- clients, onion services, and relays, and can be triggered remotely by a
- malicious endpoint. Tracked as CVE-2022-33903. Fixes bug 40626; bugfix
- on 0.4.7.5-alpha.
+++ /dev/null
- o Major bugfixes (vanguards):
- - We had omitted some checks for whether our vanguards (second layer
- guards from proposal 333) overlapped. Now make sure to pick each
- of them to be independent. Also, change the design to allow them to
- come from the same family. Fixes bug 40639; bugfix on 0.4.7.1-alpha.
+++ /dev/null
- o Major bugfixes (congestion control):
- - Implement RFC3742 Limited Slow Start. Congestion control was
- overshooting the congestion window during slow start, particularly for
- onion service activity. With this fix, we now update the congestion
- window more often during slow start, as well as dampen the exponential
- growth when the congestion window grows above a capping parameter.
- This should reduce the memory increases guard relays were seeing, as
- well as allow us to set lower queue limits to defend against
- ongoing DoS attacks. Fixes bug 40642; bugfix on 0.4.7.5-alpha.
+++ /dev/null
- o Minor bugfixes (congestion control):
- - Add a check for an integer underflow condition that might
- happen in cases where the system clock is stopped, the
- ORconn is blocked, and the endpoint sends more than a
- congestion window worth of non-data control cells at once.
- This would cause a large congestion window to be calculated
- instead of a small one. No security impact. Fixes bug 40644;
- bugfix on 0.4.7.5-alpha.
+++ /dev/null
- o Minor bugfixes (defense in depth):
- - Change a test in the netflow padding code to make it more
- _obviously_ safe against remotely triggered crashes.
- (It was safe against these before, but not obviously so.)
- Fixes bug 40645; bugfix on 0.3.1.1-alpha.
+++ /dev/null
- o Minor bugfixes (relay overload statistics):
- - Count total create cells vs dropped create cells properly, when
- assessing if our fraction of dropped cells is too high. We only
- count non-client circuits in the denominator, but we would include
- client circuits in the numerator, leading to surprising log lines
- claiming that we had dropped more than 100% of incoming create
- cells. Fixes bug 40673; bugfix on 0.4.7.1-alpha.
+++ /dev/null
- o Major bugfixes (OSX):
- - Fix coarse-time computation on Apple platforms (like Mac M1) where
- the Mach absolute time ticks do not correspond directly to
- nanoseconds. Previously, we computed our shift value wrong, which
- led us to give incorrect timing results.
- Fixes bug 40684; bugfix on 0.3.3.1-alpha.
+++ /dev/null
- o Minor bugfixes (dirauth):
- - Directory authorities stop voting a consensus "Measured" weight
- for relays with the Authority flag. Now these relays will be
- considered unmeasured, which should reserve their bandwidth
- for their dir auth role and minimize distractions from other
- roles. In place of the "Measured" weight, they now include a
- "MeasuredButAuthority" weight (not used by anything) so the
- bandwidth authority's opinion on this relay can be recorded for
- posterity. Lastly, remove the AuthDirDontVoteOnDirAuthBandwidth
- torrc option which never worked right. Fixes bugs 40698 and 40700;
- bugfix on 0.4.7.2-alpha.
+++ /dev/null
- o Major bugfixes (congestion control):
- - Avoid incrementing the congestion window when the window is not
- fully in use. Thia prevents overshoot in cases where long periods
- of low activity would allow our congestion window to grow, and
- then get followed by a burst, which would cause queue overload.
- Also improve the increment checks for RFC3742. Fixes bug 40732;
- bugfix on 0.4.7.5-alpha.
+++ /dev/null

- - Add total number of streams seen by an Exit to the MetricsPort.
- - Add congestion control RTT reset counter to MetricsPort.
- - Add DoS defenses counter to MetricsPort.
- - Add relay flags from the consensus to the MetricsPort.
- - Add total number of opened circuits to MetricsPort.
- - Add traffic stats as in number of read/written bytes in total.
+++ /dev/null
- o Minor bugfixes (state file):
