+Changes in version - 2019-02-21
+  Tor backports serveral fixes from later releases, including fixes
+  for an annoying SOCKS-parsing bug that affected users in earlier 0.3.5.x
+  releases.
+  It also includes a fix for a medium-severity security bug affecting Tor
+ and later. All Tor instances running an affected release
+  should upgrade to,,, or
+  o Major bugfixes (cell scheduler, KIST, security):
+    - Make KIST consider the outbuf length when computing what it can
+      put in the outbuf. Previously, KIST acted as though the outbuf
+      were empty, which could lead to the outbuf becoming too full. It
+      is possible that an attacker could exploit this bug to cause a Tor
+      client or relay to run out of memory and crash. Fixes bug 29168;
+      bugfix on This issue is also being tracked as
+      TROVE-2019-001 and CVE-2019-8955.
+  o Major bugfixes (networking, backport from
+    - Gracefully handle empty username/password fields in SOCKS5
+      username/password auth messsage and allow SOCKS5 handshake to
+      continue. Previously, we had rejected these handshakes, breaking
+      certain applications. Fixes bug 29175; bugfix on
+  o Minor features (compilation, backport from
+    - Compile correctly when OpenSSL is built with engine support
+      disabled, or with deprecated APIs disabled. Closes ticket 29026.
+      Patches from "Mangix".
+  o Minor features (geoip):
+    - Update geoip and geoip6 to the February 5 2019 Maxmind GeoLite2
+      Country database. Closes ticket 29478.
+  o Minor features (testing, backport from
+    - Treat all unexpected ERR and BUG messages as test failures. Closes
+      ticket 28668.
+  o Minor bugfixes (onion service v3, client, backport from
+    - Stop logging a "BUG()" warning and stacktrace when we find a SOCKS
+      connection waiting for a descriptor that we actually have in the
+      cache. It turns out that this can actually happen, though it is
+      rare. Now, tor will recover and retry the descriptor. Fixes bug
+      28669; bugfix on
+  o Minor bugfixes (IPv6, backport from
+    - Fix tor_ersatz_socketpair on IPv6-only systems. Previously, the
+      IPv6 socket was bound using an address family of AF_INET instead
+      of AF_INET6. Fixes bug 28995; bugfix on Patch from
+      Kris Katterjohn.
+  o Minor bugfixes (build, compatibility, rust, backport from
+    - Update Cargo.lock file to match the version made by the latest
+      version of Rust, so that "make distcheck" will pass again. Fixes
+      bug 29244; bugfix on
+  o Minor bugfixes (client, clock skew, backport from
+    - Select guards even if the consensus has expired, as long as the
+      consensus is still reasonably live. Fixes bug 24661; bugfix
+      on
+  o Minor bugfixes (compilation, backport from
+    - Compile correctly on OpenBSD; previously, we were missing some
+      headers required in order to detect it properly. Fixes bug 28938;
+      bugfix on Patch from Kris Katterjohn.
+  o Minor bugfixes (documentation, backport from
+    - Describe the contents of the v3 onion service client authorization
+      files correctly: They hold public keys, not private keys. Fixes
+      bug 28979; bugfix on Spotted by "Felixix".
+  o Minor bugfixes (logging, backport from
+    - Rework rep_hist_log_link_protocol_counts() to iterate through all
+      link protocol versions when logging incoming/outgoing connection
+      counts. Tor no longer skips version 5, and we won't have to
+      remember to update this function when new link protocol version is
+      developed. Fixes bug 28920; bugfix on
+  o Minor bugfixes (logging, backport from
+    - Log more information at "warning" level when unable to read a
+      private key; log more information at "info" level when unable to
+      read a public key. We had warnings here before, but they were lost
+      during our NSS work. Fixes bug 29042; bugfix on
+  o Minor bugfixes (misc, backport from
+    - The amount of total available physical memory is now determined
+      using the sysctl identifier HW_PHYSMEM (rather than HW_USERMEM)
+      when it is defined and a 64-bit variant is not available. Fixes
+      bug 28981; bugfix on Patch from Kris Katterjohn.
+  o Minor bugfixes (onion services, backport from
+    - Avoid crashing if ClientOnionAuthDir (incorrectly) contains more
+      than one private key for a hidden service. Fixes bug 29040; bugfix
+      on
+    - In hs_cache_store_as_client() log an HSDesc we failed to parse at
+      "debug" level. Tor used to log it as a warning, which caused very
+      long log lines to appear for some users. Fixes bug 29135; bugfix
+      on
+    - Stop logging "Tried to establish rendezvous on non-OR circuit..."
+      as a warning. Instead, log it as a protocol warning, because there
+      is nothing that relay operators can do to fix it. Fixes bug 29029;
+      bugfix on
+  o Minor bugfixes (tests, directory clients, backport from
+    - Mark outdated dirservers when Tor only has a reasonably live
+      consensus. Fixes bug 28569; bugfix on
+  o Minor bugfixes (tests, backport from
+    - Detect and suppress "bug" warnings from the util/time test on
+      Windows. Fixes bug 29161; bugfix on
+    - Do not log an error-level message if we fail to find an IPv6
+      network interface from the unit tests. Fixes bug 29160; bugfix
+      on
+  o Minor bugfixes (usability, backport from
+    - Stop saying "Your Guard ..." in pathbias_measure_{use,close}_rate().
+      Some users took this phrasing to mean that the mentioned guard was
+      under their control or responsibility, which it is not. Fixes bug
+      28895; bugfix on Tor
