ChangeLog

+Changes in version 0.4.3.2-alpha - 2020-02-10
+  This is the second stable alpha release in the Tor 0.4.3.x series. It
+  fixes several bugs present in the previous alpha release. Anybody
+  running the previous alpha should upgrade, and look for bugs in this
+  one instead.
+
+  o Major bugfixes (Onion service client, authorization):
+    - On a NEWNYM signal, purge the ephemeral client authorization
+      cache. The permanent ones are kept. Fixes bug 33139; bugfix
+      on 0.4.3.1-alpha.
+
+  o Minor features (best practices tracker):
+    - Practracker now supports a --regen-overbroad option to regenerate
+      the exceptions file, but only to revise exceptions to be _less_
+      tolerant of best-practices violations. Closes ticket 32372.
+
+  o Minor features (continuous integration):
+    - Run Doxygen Makefile target on Travis. Closes ticket 32455.
+    - Stop allowing failures on the Travis CI stem tests job. It looks
+      like all the stem hangs we were seeing before are now fixed.
+      Closes ticket 33075.
+
+  o Minor bugfixes (build system):
+    - Some configure options were either missing or incorrect in the
+      configure summary. Fixes bug 32230; bugfix on 0.4.3.1-alpha.
+
+  o Minor bugfixes (controller protocol):
+    - Fix a memory leak introduced by refactoring of control reply
+      formatting code. Fixes bug 33039; bugfix on 0.4.3.1-alpha.
+    - Fix a memory leak in GETINFO responses. Fixes bug 33103; bugfix
+      on 0.4.3.1-alpha.
+    - When receiving "ACTIVE" or "DORMANT" signals on the control port,
+      report them as SIGNAL events. Fixes bug 33104; bugfix
+      on 0.4.0.1-alpha.
+
+  o Minor bugfixes (logging):
+    - If we encounter a bug when flushing a buffer to a TLS connection,
+      only log the bug once per invocation of the Tor process.
+      Previously we would log with every occurrence, which could cause
+      us to run out of disk space. Fixes bug 33093; bugfix
+      on 0.3.2.2-alpha.
+    - When logging a bug, do not say "Future instances of this warning
+      will be silenced" unless we are actually going to do so.
+      Previously we would say this whenever a BUG() check failed in the
+      code. Fixes bug 33095; bugfix on 0.4.1.1-alpha.
+
+  o Minor bugfixes (onion service v2):
+    - Move a series of warnings to protocol warning level because they
+      can all be triggered remotely by a malformed request. Fixes bug
+      32706; bugfix on 0.1.1.14-alpha.
+
+  o Minor bugfixes (onion service v3, client authorization):
+    - When removing client authorization credentials using the control
+      port, also remove the associated descriptor so they don't linger
+      and are still usable hence making the onion service behind client
+      authorization reachable. Fixes bug 33148; bugfix on 0.4.3.1-alpha.
+
+  o Minor bugfixes (pluggable transports):
+    - Lower the log level of standard error messages from a PT from
+      warning to info. Fixes bug 33005; bugfix on 0.4.0.1-alpha.
+
+  o Minor bugfixes (rust, build):
+    - Fix a syntax warning given by newer versions of Rust, and creating
+      problems for our continuous integration. Fixes bug 33212; bugfix
+      on 0.3.5.1-alpha.
+
+  o Minor bugfixes (TLS bug handling):
+    - When encountering a bug in buf_read_freom_tls(), return a "MISC"
+      error code rather than "WANTWRITE". This change might help avoid
+      some CPU-wasting loops if the bug is ever triggered. Bug reported
+      by opara. Fixes bug 32673; bugfix on 0.3.0.4-alpha.
+
+  o Code simplification and refactoring (mainloop):
+    - Simplify the ip_address_changed() function by removing redundant
+      checks. Closes ticket 33091.
+
+  o Documentation (manpage):
+    - Split Circuit Timeout options and Node Selection options into
+      their own sections of the tor manpage. Closes tickets 32928 and
+      32929. Work by Swati Thacker as part of Google Season of Docs.
