+Changes in version 0.3.2.2-alpha - 2017-09-29
+ Tor-0.3.2.2-alpha is the second release in the 0.3.2 series. This
+ release fixes several minor bugs in the new scheduler and next-
+ generation onion services; both features were newly added in the 0.3.2
+ series. Other fixes in this alpha include several fixes for non-fatal
+ tracebacks which would appear in logs.
+
+ With the aim to stabilise the 0.3.2 series by 15 December 2017, this
+ alpha does not contain any substantial new features. Minor features
+ include better testing and logging.
+
+ The following comprises the complete list of changes included
+ in tor-0.3.2.2-alpha:
+
+ o Major bugfixes (relay, crash, assertion failure):
+ - Fix a timing-based assertion failure that could occur when the
+ circuit out-of-memory handler freed a connection's output buffer.
+ Fixes bug 23690; bugfix on 0.2.6.1-alpha.
+
+ o Major bugfixes (scheduler):
+ - If a channel is put into the scheduler's pending list, then it
+ starts closing, and then if the scheduler runs before it finishes
+ closing, the scheduler will get stuck trying to flush its cells
+ while the lower layers refuse to cooperate. Fix that race
+ condition by given the scheduler an escape method. Fixes bug
+ 23676; bugfix on 0.3.2.1-alpha
+
+ o Minor features (build, compilation):
+ - The "check-changes" feature is now part of the "make check" tests;
+ we'll use it to try to prevent misformed changes files from
+ accumulating. Closes ticket 23564.
+ - Tor builds should now fail if there are any mismatches between the
+ C type representing a configuration variable and the C type the
+ data-driven parser uses to store a value there. Previously, we
+ needed to check these by hand, which sometimes led to mistakes.
+ Closes ticket 23643.
+
+ o Minor features (directory authorities):
+ - Remove longclaw's IPv6 address, as it will soon change. Authority
+ IPv6 addresses were originally added in 0.2.8.1-alpha. This leaves
+ 3/8 directory authorities with IPv6 addresses, but there are also
+ 52 fallback directory mirrors with IPv6 addresses. Resolves 19760.
+
+ o Minor features (hidden service, circuit, logging):
+ - Improve logging of many callsite in the circuit subsystem to print
+ the circuit identifier(s).
+ - Log when we cleanup an intro point from a service so we know when
+ and for what reason it happened. Closes ticket 23604.
+
+ o Minor features (logging):
+ - Log more circuit information whenever we are about to try to
+ package a relay cell on a circuit with a nonexistent n_chan.
+ Attempt to diagnose ticket 8185.
+ - Improve info-level log identification of particular circuits, to
+ help with debugging. Closes ticket 23645.
+
+ o Minor features (relay):
+ - When choosing which circuits can be expired as unused, consider
+ circuits from clients even if those clients used regular CREATE
+ cells to make them; and do not consider circuits from relays even
+ if they were made with CREATE_FAST. Part of ticket 22805.
+
+ o Minor features (robustness):
+ - Change several fatal assertions when flushing buffers into non-
+ fatal assertions, to prevent any recurrence of 23690.
+
+ o Minor features (spec conformance, bridge, diagnostic):
+ - When handling the USERADDR command on an ExtOrPort, warn when the
+ transports provides a USERADDR with no port. In a future version,
+ USERADDR commands of this format may be rejected. Detects problems
+ related to ticket 23080.
+
+ o Minor features (testing):
+ - Add a unit test to make sure that our own generated platform
+ string will be accepted by directory authorities. Closes
+ ticket 22109.
+
+ o Minor bugfixes (bootstrapping):
+ - When warning about state file clock skew, report the correct
+ direction for the detected skew. Fixes bug 23606; bugfix
+ on 0.2.8.1-alpha.
+ - Avoid an assertion failure when logging a state file clock skew
+ very early in bootstrapping. Fixes bug 23607; bugfix
+ on 0.3.2.1-alpha.
+
+ o Minor bugfixes (build, compilation):
+ - Fix a compilation warning when building with zstd support on
+ 32-bit platforms. Fixes bug 23568; bugfix on 0.3.1.1-alpha. Found
+ and fixed by Andreas Stieger.
+ - When searching for OpenSSL, don't accept any OpenSSL library that
+ lacks TLSv1_1_method(): Tor doesn't build with those versions.
+ Additionally, look in /usr/local/opt/openssl, if it's present.
+ These changes together repair the default build on OSX systems
+ with Homebrew installed. Fixes bug 23602; bugfix on 0.2.7.2-alpha.
+
+ o Minor bugfixes (compression):
+ - Handle a pathological case when decompressing Zstandard data when
+ the output buffer size is zero. Fixes bug 23551; bugfix
+ on 0.3.1.1-alpha.
+
+ o Minor bugfixes (documentation):
+ - Fix manpage to not refer to the obsolete (and misspelled)
+ UseEntryGuardsAsDirectoryGuards parameter in the description of
+ NumDirectoryGuards. Fixes bug 23611; bugfix on 0.2.4.8-alpha.
+
+ o Minor bugfixes (hidden service v3):
+ - Don't log an assertion failure when we can't find the right
+ information to extend to an introduction point. In rare cases,
+ this could happen, causing a warning, even though tor would
+ recover gracefully. Fixes bug 23159; bugfix on 0.3.2.1-alpha.
+ - Pad RENDEZVOUS cell up to the size of the legacy cell which is
+ much bigger so the rendezvous point can't distinguish which hidden
+ service protocol is being used. Fixes bug 23420; bugfix
+ on 0.3.2.1-alpha.
+
+ o Minor bugfixes (hidden service, relay):
+ - Avoid a possible double close of a circuit by the intro point on
+ error of sending the INTRO_ESTABLISHED cell. Fixes bug 23610;
+ bugfix on 0.3.0.1-alpha.
+
+ o Minor bugfixes (logging, relay shutdown, annoyance):
+ - When a circuit is marked for close, do not attempt to package any
+ cells for channels on that circuit. Previously, we would detect
+ this condition lower in the call stack, when we noticed that the
+ circuit had no attached channel, and log an annoying message.
+ Fixes bug 8185; bugfix on 0.2.5.4-alpha.
+
+ o Minor bugfixes (scheduler):
+ - When switching schedulers due to a consensus change, we didn't
+ give the new scheduler a chance to react to the consensus. Fix
+ that. Fixes bug 23537; bugfix on 0.3.2.1-alpha
+ - Make the KISTSchedRunInterval option a non negative value. With
+ this, the way to disable KIST through the consensus is to set it
+ to 0. Fixes bug 23539; bugfix on 0.3.2.1-alpha.
+ - Only notice log the selected scheduler when we switch scheduler
+ types. Fixes bug 23552; bugfix on 0.3.2.1-alpha.
+ - Avoid a compilation warning on macOS in scheduler_ev_add() caused
+ by a different tv_usec data type. Fixes bug 23575; bugfix
+ on 0.3.2.1-alpha.
+ - Make a hard exit if tor is unable to pick a scheduler which can
+ happen if the user specifies a scheduler type that is not
+ supported and not other types in Schedulers. Fixes bug 23581;
+ bugfix on 0.3.2.1-alpha.
+ - Properly initialize the scheduler last run time counter so it is
+ not 0 at the first tick. Fixes bug 23696; bugfix on 0.3.2.1-alpha.
+
+ o Minor bugfixes (testing):
+ - Capture and detect several "Result does not fit" warnings in unit
+ tests on platforms with 32-bit time_t. Fixes bug 21800; bugfix
+ on 0.2.9.3-alpha.
+ - Fix additional channelpadding unit test failures by using mocked
+ time instead of actual time for all tests. Fixes bug 23608; bugfix
+ on 0.3.1.1-alpha.
+ - The removal of some old scheduler options caused some tests to
+ fail on BSD systems. Assume current behavior is correct and make
+ the tests pass again. Fixes bug 23566; bugfix on 0.3.2.1-alpha.
+
+ o Code simplification and refactoring:
+ - Remove various ways of testing circuits and connections for
+ "clientness"; instead, favor channel_is_client(). Part of
+ ticket 22805.
+
+ o Deprecated features:
+ - The ReachableDirAddresses and ClientPreferIPv6DirPort options are
+ now deprecated; they do not apply to relays, and they have had no
+ effect on clients since 0.2.8.x. Closes ticket 19704.
+
+ o Documentation:
+ - HiddenServiceVersion man page entry wasn't mentioning the now
+ supported version 3. Fixes ticket 23580; bugfix on 0.3.2.1-alpha.
+ - Clarify that the Address option is entirely about setting an
+ advertised IPv4 address. Closes ticket 18891.
+ - Clarify the manpage's use of the term "address" to clarify what
+ kind of address is intended. Closes ticket 21405.
+ - Document that onion service subdomains are allowed, and ignored.
+ Closes ticket 18736.
