+Changes in version 0.3.4.6-rc - 2018-08-06
+  Tor 0.3.4.6-rc fixes several small compilation, portability, and
+  correctness issues in previous versions of Tor. This version is a
+  release candidate: if no serious bugs are found, we expect that the
+  stable 0.3.4 release will be (almost) the same as this release.
+
+  o Minor features (compilation):
+    - When building Tor, prefer to use Python 3 over Python 2, and more
+      recent (contemplated) versions over older ones. Closes
+      ticket 26372.
+
+  o Minor features (geoip):
+    - Update geoip and geoip6 to the July 3 2018 Maxmind GeoLite2
+      Country database. Closes ticket 26674.
+
+  o Minor features (Rust, portability):
+    - Rust cross-compilation is now supported. Closes ticket 25895.
+
+  o Minor bugfixes (compilation):
+    - Fix a compilation warning on some versions of GCC when building
+      code that calls routerinfo_get_my_routerinfo() twice, assuming
+      that the second call will succeed if the first one did. Fixes bug
+      26269; bugfix on 0.2.8.2-alpha.
+
+  o Minor bugfixes (controller):
+    - Report the port correctly when a port is configured to bind to
+      "auto". Fixes bug 26568; bugfix on 0.3.4.1-alpha.
+    - Parse the "HSADDRESS=" parameter in HSPOST commands properly.
+      Previously, it was misparsed and ignored. Fixes bug 26523; bugfix
+      on 0.3.3.1-alpha. Patch by "akwizgran".
+
+  o Minor bugfixes (correctness, flow control):
+    - Upon receiving a stream-level SENDME cell, verify that our window
+      has not grown too large. Fixes bug 26214; bugfix on svn
+      r54 (pre-0.0.1)
+
+  o Minor bugfixes (memory, correctness):
+    - Fix a number of small memory leaks identified by coverity. Fixes
+      bug 26467; bugfix on numerous Tor versions.
+
+  o Minor bugfixes (testing, compatibility):
+    - When running the ntor_ref.py and hs_ntor_ref.py tests, make sure
+      only to pass strings (rather than "bytes" objects) to the Python
+      subprocess module. Python 3 on Windows seems to require this.
+      Fixes bug 26535; bugfix on 0.2.5.5-alpha (for ntor_ref.py) and
+      0.3.1.1-alpha (for hs_ntor_ref.py).
