+Changes in version 0.4.6.1-alpha - 2021-03-??
+ Tor 0.4.6.1-alpha is the first alpha release in the 0.4.6.x series. It
+ improves client circuit performance, adds missing features, and
+ improves some of our DoS handling and statistics reporting. It also
+ includes numerous smaller bugfixes.
+
+ o Major features (control port, onion services):
+ - Add controller support for creating version 3 onion services with
+ client authorization. Previously, only v2 onion services could be
+ created with client authorization. Closes ticket 40084. Patch by
+ Neel Chauhan.
+
+ o Major features (directory authorityl):
+ - When voting for a relay with a Sybil-like appearance, add the
+ Sybil flag when clearing out the other flags. This lets a relay
+ operator know why their relay hasn't been voted on. Closes ticket
+ 40255. Patch by Neel Chauhan.
+
+ o Major features (relay, denial of service):
+ - Add a new DoS subsystem feature to control the rate of client
+ connections for relays. Closes ticket 40253.
+
+ o Major features (statistics):
+ - Relays now also publish statistics about the number of v3 onion
+ services and volume of v3 onion service traffic, in the same
+ manner they already do for v2 onions. Closes ticket 23126.
+
+ o Major bugfixes (circuit build timeout):
+ - Improve the accuracy of our circuit build timeout calculation for
+ 60%, 70%, and 80% build rates for various guard choices. We now
+ use a maximum likelihood estimator for Pareto parameters of the
+ circuit build time distribution, instead of a "right-censored
+ estimator". This causes clients to ignore circuits that never
+ finish building in their timeout calculations. Previously, clients
+ were counting such unfinished circuits as having the highest
+ possible build time value, when in reality these circuits most
+ likely just contain relays that are offline. We also now wait a
+ bit longer to let circuits complete for measurement purposes,
+ lower the minimum possible effective timeout from 1.5 seconds to
+ 10ms, and increase the resolution of the circuit build time
+ histogram from 50ms bin widths to 10ms bin widths. Additionally,
+ we alter our estimate Xm by taking the maximum of the top 10 most
+ common build time values of the 10ms histogram, and compute Xm as
+ the average of these. Fixes bug 40168; bugfix on 0.2.2.14-alpha.
+ - Remove max_time calculation and associated warn from circuit build
+ timeout 'alpha' parameter estimation, as this is no longer needed
+ by our new estimator from 40168. Fixes bug 34088; bugfix
+ on 0.2.2.9-alpha.
+
+ o Major bugfixes (signing key):
+ - In the tor-gencert utility, give an informative error message if
+ the passphrase given in `--create-identity-key` is too short.
+ Fixes bug 40189; bugfix on 0.2.0.1-alpha. Patch by Neel Chauhan.
+
+ o Minor features (bridge):
+ - We now announce the URL to Tor's new bridge status at
+ https://bridges.torproject.org/ when Tor is configured to run as a
+ bridge relay. Closes ticket 30477.
+
+ o Minor features (build system):
+ - New "make lsp" command to auto generate the compile_commands.json
+ file used by the ccls server. The "bear" program is needed for
+ this. Closes ticket 40227.
+
+ o Minor features (command-line interface):
+ - Add build informations to `tor --version` in order to ease
+ reproducible builds. Closes ticket 32102.
+ - When parsing command-line flags that take an optional argument,
+ treat the argument as absent if it would start with a '-'
+ character. Arguments in that form are not intelligible for any of
+ our optional-argument flags. Closes ticket 40223.
+ - Allow a relay operator to list the ed25519 keys on the command
+ line by adding the `rsa` and `ed25519` arguments to the
+ --list-fingerprint flag to show the respective RSA and ed25519
+ relay fingerprint. Closes ticket 33632. Patch by Neel Chauhan.
+
+ o Minor features (control port, stream handling):
+ - Add the stream ID argument to the event line in the ADDRMAP
+ control event. Closes ticket 40249. Patch by Neel Chauhan.
+
+ o Minor features (logging):
+ - Change the DoS subsystem heartbeat line format so be more clear on
+ what has been detected/rejected and which option is disabled if
+ any. Closes ticket 40308.
+ - In src/core/mainloop/mainloop.c and src/core/mainloop/connection.c,
+ put brackets around IPv6 addresses in log messages. Closes ticket
+ 40232. Patch by Neel Chauhan.
+
+ o Minor features (performance, windows):
+ - Use SRWLocks to implement locking on Windows. Replaces the
+ critical section locking implementation with the faster SRWLocks
+ available since Windows Vista. Closes ticket 17927. Patch by
+ Daniel Pinto.
+
+ o Minor features (protocol, proxy support, defense in depth):
+ - Close HAProxy connections if they somehow manage to send us data
+ before we start reading. Closes another case of ticket 40017.
+
+ o Minor features (tests, portability):
+ - Port the hs_build_address.py test script to work with recent
+ versions of python. Closes ticket 40213. Patch from
+ Samanta Navarro.
+
+ o Minor bugfixes (build):
+ - Mini-report in the configure script now shows whether or not lzma
+ and zstd have been used, not just if enable flag passed in. Fixes
+ bug 40236; bugfix on 0.4.3.1-alpha.
+
+ o Minor bugfixes (compatibility):
+ - Fix a failure in the test cases when running on the hppa
+ architecture, along with a related test that might fail on other
+ architectures in the future. Fixes bug 40274; bugfix
+ on 0.2.5.1-alpha.
+
+ o Minor bugfixes (directory authorities, voting):
+ - Add a new consensus method (31) to support any future changes that
+ authorities decide to make to the value of bwweightscale or
+ maxunmeasuredbw. Previously, there was a bug that prevented the
+ authorities from parsing these consensus parameters correctly under
+ most circumstances. Fixes bug 19011; bugfix on 0.2.2.10-alpha.
+
+ o Minor bugfixes (ipv6):
+ - Allow non-SOCKSPorts to disable IPv4, IPv6, and Prefer IPv4. Some
+ rare configs might break, but in this case you can disable
+ NoIPv4Traffic and NoIPv6Traffic as needed. Fixes bug 33607; bugfix
+ on 0.4.1.1-alpha. Patch by Neel Chauhan.
+
+ o Minor bugfixes (key generation):
+ - Do not require a valid torrc when using the `--keygen` argument to
+ generate a signing key. This allows us to generate keys on systems
+ or users which may not run Tor. Fixes bug 40235; bugfix on
+ 0.2.7.2-alpha. Patch by Neel Chauhan.
+
+ o Minor bugfixes (onion services, logging):
+ - Downgrade the severity of a few rendezvous circuit-related
+ warnings from warning to info. Fixes bug 40207; bugfix on
+ 0.3.2.1-alpha. Patch by Neel Chauhan.
+
+ o Minor bugfixes (relay):
+ - Reduce the compression level for data streaming from HIGH to LOW.
+ Fixes bug 40301; bugfix on 0.3.5.1-alpha.
+
+ o Code simplification and refactoring:
+ - Remove the orconn_ext_or_id_map structure and related functions.
+ Nothing outside of unit tests looks up anything in this structure.
+ Closes ticket 33383. Patch by Neel Chauhan.
+
+ o Code simplification and refactoring (metrics, DoS):
+ - Move the DoS subsystem into the subsys manager including its
+ configuration options. Closes ticket 40261.
+
+ o Removed features (relay):
+ - Because DirPorts are only used on authorities, relays no longer
+ advertise them. Similarly, self-testing for DirPorts has been
+ disabled, since an unreachable DirPort is no reason for a relay
+ not to advertise itself. (Configuring a DirPort will still work,
+ for now.) Closes ticket 40282.
