-Changes in version 0.4.9.1-alpha - 2024-12-03
-  This is the first alpha of the 0.4.9.x series. This release mostly consists
-  of bugfixes including some major ones. There are several minor features in
-  this release but no large new subsystem. Most of the fixes in this release
-  are already in 0.4.8.x stable series.
-
-  o Major bugfixes (circuit building):
-    - Conflux circuit building was ignoring the "predicted ports"
-      feature, which aims to make Tor stop building circuits if there
-      have been no user requests lately. This bug led to every idle Tor
-      on the network building and discarding circuits every 30 seconds,
-      which added overall load to the network, used bandwidth and
-      battery from clients that weren't actively using their Tor, and
-      kept sockets open on guards which added connection padding
-      essentially forever. Fixes bug 40981; bugfix on 0.4.8.1-alpha;
-
-  o Major bugfixes (conflux):
-    - Fix an issue that prevented us from pre-building more conflux sets
-      after existing sets had been used. Fixes bug 40862; bugfix
-      on 0.4.8.1-alpha.
-
-  o Major bugfixes (guard usage):
-    - When Tor excluded a guard due to temporary circuit restrictions,
-      it considered *additional* primary guards for potential usage by
-      that circuit. This could result in more than the specified number
-      of guards (currently 2) being used, long-term, by the tor client.
-      This could happen when a Guard was also selected as an Exit node,
-      but it was exacerbated by the Conflux guard restrictions. Both
-      instances have been fixed. Fixes bug 40876; bugfix
-      on 0.3.0.1-alpha.
-
-  o Major bugfixes (onion service):
-    - Fix a reliability issue where services were expiring their
-      introduction points every consensus update. This caused
-      connectivity issues for clients caching the old descriptor and
-      intro points. Bug reported and fixed by gitlab user
-      @hyunsoo.kim676. Fixes bug 40858; bugfix on 0.4.7.5-alpha.
-
-  o Major bugfixes (onion service, TROVE-2023-006):
-    - Fix a possible hard assert on a NULL pointer when recording a
-      failed rendezvous circuit on the service side for the MetricsPort.
-      Fixes bug 40883; bugfix on 0.4.8.1-alpha
-
-  o Major bugfixes (sandbox):
-    - Fix sandbox to work on architectures that use Linux's generic
-      syscall interface, extending support for AArch64 (ARM64) and
-      adding support for RISC-V, allowing test_include.sh and the
-      sandbox unit tests to pass on these systems even when building
-      with fragile hardening enabled. Fixes bugs 40465 and 40599; bugfix
-      on 0.2.5.1-alpha.
-
-  o Major bugfixes (TROVE-2023-004, relay):
-    - Mitigate an issue when Tor compiled with OpenSSL can crash during
-      handshake with a remote relay. Fixes bug 40874; bugfix
-      on 0.2.7.2-alpha.
-
-  o Major bugfixes (TROVE-2023-007, exit):
-    - Improper error propagation from a safety check in conflux leg
-      linking lead to a desynchronization of which legs were part of a
-      conflux set, ultimately causing a UAF and NULL pointer dereference
-      crash on Exit relays. Fixes bug 40897; bugfix on 0.4.8.1-alpha.
-
-  o Minor feature (authority):
-    - Reject 0.4.7.x series at the authority level. Closes ticket 40896.
-
-  o Minor feature (bridges, pluggable transport):
-    - Add STATUS TYPE=version handler for Pluggable Transport. This
-      allows us to gather version statistics on Pluggable Transport
-      usage from bridge servers on our metrics portal. Closes
-      ticket 11101.
-
-  o Minor feature (defense in depth):
-    - Verify needle is smaller than haystack before calling memmem.
-      Closes ticket 40854.
-
-  o Minor feature (dirauth):
-    - Add back faravahar with a new address and new keys. Closes 40689.
-
-  o Minor feature (dirauth, tor26):
-    - New IP address and keys.
-
-  o Minor feature (directory authority):
-    - Allow BandwidthFiles "node_id" KeyValue without the dollar sign at
-      the start of the hexdigit, in order to easier database queries
-      combining Tor documents in which the relays fingerprint does not
-      include it. Fixes bug 40891; bugfix on 0.4.7 (all supported
-      versions of Tor).
-    - Introduce MinimalAcceptedServerVersion to allow modification of
-      minimal accepted version for relays without requiring a new tor
-      release. Closes ticket 40817.
-
-  o Minor feature (exit policies):
-    - Implement reevaluating new exit policy against existing
-      connections. This is controlled by new config option
-      ReevaluateExitPolicy, defaulting to 0. Closes ticket 40676.
-
-  o Minor feature (exit relay, DoS resitance):
-    - Implement a token-bucket based rate limiter for stream creation
-      and resolve request. It is configured by the DoSStream* family of
-      configuration options. Closes ticket 40736.
-
-  o Minor feature (metrics port):
-    - New metrics on the MetricsPort for the number of BUG() that
-      occurred at runtime. Closes MR 760.
-
-  o Minor feature (metrics port, relay):
-    - Add new metrics for relays on the MetricsPort namely the count of
-      drop cell, destroy cell and the number of circuit protocol
-      violation seen that lead to a circuit close. Closes ticket 40816.
-
-  o Minor feature (testing):
-    - test-network now unconditionally includes IPv6 instead of trying
-      to detect IPv6 support.
-
-  o Minor feature (testing, CI):
-    - Use a fixed version of chutney (be881a1e) instead of its current
-      HEAD. This version should also be preferred when testing locally.
-
-  o Minor features (debugging, compression):
-    - Log the input and output buffer sizes when we detect a potential
-      compression bomb. Diagnostic for ticket 40739.
-
-  o Minor features (forward-compatibility):
-    - We now correctly parse microdescriptors and router descriptors
-      that do not include TAP onion keys. (For backward compatibility,
-      authorities continue to require these keys.) Implements part of
-      proposal 350.
-
-  o Minor features (portability, android):
-    - Use /data/local/tmp for data storage on Android by default. Closes
-      ticket 40487. Patch from Hans-Christoph Steiner.
-
-  o Minor features (SOCKS):
-    - Detect invalid SOCKS5 username/password combinations according to
-      new extended parameters syntax. (Currently, this rejects any
-      SOCKS5 username beginning with "<torS0X>", except for the username
-      "<torS0X>0". Such usernames are now reserved to communicate
-      additional parameters with other Tor implementations.) Implements
-      proposal 351.
-
-  o Minor bugfix (circuit):
-    - Remove a log_warn being triggered by a protocol violation that
-      already emits a protocol warning log. Fixes bug 40932; bugfix
-      on 0.4.8.1-alpha.
-
-  o Minor bugfix (defensive programming):
-    - Disable multiple BUG warnings of a missing relay identity key when
-      starting an instance of Tor compiled without relay support. Fixes
-      bug 40848; bugfix on 0.4.3.1-alpha.
-
-  o Minor bugfix (MetricsPort, relay):
-    - Handle rephist tracking of ntor and ntor_v3 handshakes
-      individually such that MetricsPort exposes the correct values.
-      Fixes bug 40638; bugfix on 0.4.7.11.
-
-  o Minor bugfix (NetBSD, compilation):
-    - Fix compilation issue on NetBSD by avoiding an unnecessary
-      dependency on "huge" page mappings in Equi-X. Fixes bug 40843;
-      bugfix on 0.4.8.1-alpha.
-
-  o Minor bugfix (NetBSD, testing):
-    - Fix test failures in "crypto/hashx" and "slow/crypto/equix" on
-      x86_64 and aarch64 NetBSD hosts, by adding support for
-      PROT_MPROTECT() flags. Fixes bug 40844; bugfix on 0.4.8.1-alpha.
-
-  o Minor bugfix (process):
-    - Avoid closing all possible FDs when spawning a process (PT). On
-      some systems, this could lead to 3+ minutes hang. Fixes bug 40990;
-      bugfix on 0.3.5.1-alpha.
-
-  o Minor bugfix (relay, sandbox):
-    - Disable a sandbox unit test that is failing on Debian Sid breaking
-      our nightly packages. Fixes bug 40918; bugfix on 0.3.5.1-alpha.
-
-  o Minor bugfixes (bridge authority):
-    - When reporting a pseudo-networkstatus as a bridge authority, or
-      answering "ns/purpose/*" controller requests, include accurate
-      published-on dates from our list of router descriptors. Fixes bug
-      40855; bugfix on 0.4.8.1-alpha.
-
-  o Minor bugfixes (bridge):
-    - Don't warn when BridgeRelay is 1 and ExitRelay is explicitly set
-      to 0. Fixes bug 40884; bugfix on 0.4.8.3-rc.
-
-  o Minor bugfixes (bridges, statistics):
-    - Correctly report statistics for client count over Pluggable
-      transport. Fixes bug 40871; bugfix on 0.4.8.4
-
-  o Minor bugfixes (compiler warnings):
-    - Make sure the two bitfields in the half-closed edge struct are
-      unsigned, as we're using them for boolean values and assign 1 to
-      them. Fixes bug 40911; bugfix on 0.4.7.2-alpha.
-
-  o Minor bugfixes (compression, zstd):
-    - Use less frightening language and lower the log-level of our run-
-      time ABI compatibility check message in our Zstd compression
-      subsystem. Fixes bug 40815; bugfix on 0.4.3.1-alpha.
-
-  o Minor bugfixes (conflux):
-    - Avoid a potential hard assert (crash) when sending a cell on a
-      Conflux set. Fixes bug 40921; bugfix on 0.4.8.1-alpha.
-    - Demote a relay-side warn about too many legs to ProtocolWarn, as
-      there are conditions that it can briefly happen during set
-      construction. Also add additional set logging details for all
-      error cases. Fixes bug 40841; bugfix on 0.4.8.1-alpha.
-    - Make sure we don't process a closed circuit when packaging data.
-      This lead to a non fatal BUG() spamming logs. Fixes bug 40908;
-      bugfix on 0.4.8.1-alpha.
-    - Prevent non-fatal assert stacktrace caused by using conflux sets
-      during their teardown process. Fixes bug 40842; bugfix
-      on 0.4.8.1-alpha.
-
-  o Minor bugfixes (conflux, client):
-    - Avoid a non fatal assert caused by data coming in on a conflux set
-      that is being freed during shutdown. Fixes bug 40870; bugfix
-      on 0.4.8.1-alpha.
-
-  o Minor bugfixes (directory authorities):
-    - Add a warning when publishing a vote or signatures to another
-      directory authority fails. Fixes bug 40910; bugfix
-      on 0.2.0.3-alpha.
-
-  o Minor bugfixes (directory authority):
-    - Look at the network parameter "maxunmeasuredbw" with the correct
-      spelling. Fixes bug 40869; bugfix on 0.4.6.1-alpha.
-
-  o Minor bugfixes (memleak, authority):
-    - Fix a small memleak when computing a new consensus. This only
-      affects directory authorities. Fixes bug 40966; bugfix
-      on 0.3.5.1-alpha.
-
-  o Minor bugfixes (memory):
-    - Fix a pointer free that wasn't set to NULL afterwards which could
-      be reused by calling back in the free all function. Fixes bug
-      40989; bugfix on 0.4.8.13.
-    - Fix memory leaks of the CPU worker code during shutdown. Fixes bug
-      833; bugfix on 0.3.5.1-alpha.
-
-  o Minor bugfixes (sandbox, bwauth):
-    - Fix sandbox to work for bandwidth authority. Fixes bug 40933;
-      bugfix on 0.2.2.1-alpha
-
-  o Minor bugfixes (testing):
-    - Enabling TestingTorNetwork no longer forces fast hidden service
-      intro point rotation. This reduces noise and errors when using
-      hidden services with TestingTorNetwork enabled. Fixes bug 40922;
-      bugfix on 0.3.2.1-alpha.
-
-  o Minor bugfixes (tor-resolve):
-    - Create socket with correct family as given by sockshost, fixes
-      IPv6. Fixes bug 40982; bugfix on 0.4.9.0-alpha.
-
-  o Minor bugfixes (vanguards addon support):
-    - Count the conflux linked cell as valid when it is successfully
-      processed. This will quiet a spurious warn in the vanguards addon.
-      Fixes bug 40878; bugfix on 0.4.8.1-alpha.
-
-  o Removed features:
-    - Directory authorities no longer support consensus methods before
-      method 32. Closes ticket 40835.
-
-  o Removed features (directory authority):
-    - We include a new consensus method that removes support for
-      computing "package" lines in consensus documents. This feature was
-      never used, and support for including it in our votes was removed
-      in 0.4.2.1-alpha. Finishes implementation of proposal 301.
-
-  o Removed features (obsolete):
-    - Relays no longer support the obsolete TAP circuit extension
-      protocol. (For backward compatibility, however, relays still
-      continue to include TAP keys in their descriptors.) Implements
-      part of proposal 350.
-    - Removed some vestigial code for selecting the TAP circuit
-      extension protocol.
-
