+Changes in version 0.4.5.8 - 2021-05-10
+  Tor 0.4.5.8 fixes several bugs in earlier version, backporting fixes
+  from the 0.4.6.x series.
+
+  o Minor features (compatibility, Linux seccomp sandbox, backport from 0.4.6.3-rc):
+    - Add a workaround to enable the Linux sandbox to work correctly
+      with Glibc 2.33. This version of Glibc has started using the
+      fstatat() system call, which previously our sandbox did not allow.
+      Closes ticket 40382; see the ticket for a discussion of trade-offs.
+
+  o Minor features (compilation, backport from 0.4.6.3-rc):
+    - Make the autoconf script build correctly with autoconf versions
+      2.70 and later. Closes part of ticket 40335.
+
+  o Minor features (fallback directory list, backport from 0.4.6.2-alpha):
+    - Regenerate the list of fallback directories to contain a new set
+      of 200 relays. Closes ticket 40265.
+
+  o Minor features (geoip data):
+    - Update the geoip files to match the IPFire Location Database, as
+      retrieved on 2021/05/07.
+
+  o Minor features (onion services):
+    - Add warning message when connecting to now deprecated v2 onion
+      services. As announced, Tor 0.4.5.x is the last series that will
+      support v2 onions. Closes ticket 40373.
+
+  o Minor bugfixes (bridge, pluggable transport, backport from 0.4.6.2-alpha):
+    - Fix a regression that made it impossible start Tor using a bridge
+      line with a transport name and no fingerprint. Fixes bug 40360;
+      bugfix on 0.4.5.4-rc.
+
+  o Minor bugfixes (build, cross-compilation, backport from 0.4.6.3-rc):
+    - Allow a custom "ar" for cross-compilation. Our previous build
+      script had used the $AR environment variable in most places, but
+      it missed one. Fixes bug 40369; bugfix on 0.4.5.1-alpha.
+
+  o Minor bugfixes (channel, DoS, backport from 0.4.6.2-alpha):
+    - Fix a non-fatal BUG() message due to a too-early free of a string,
+      when listing a client connection from the DoS defenses subsystem.
+      Fixes bug 40345; bugfix on 0.4.3.4-rc.
+
+  o Minor bugfixes (compiler warnings, backport from 0.4.6.3-rc):
+    - Fix an indentation problem that led to a warning from GCC 11.1.1.
+      Fixes bug 40380; bugfix on 0.3.0.1-alpha.
+
+  o Minor bugfixes (controller, backport from 0.4.6.1-alpha):
+    - Fix a "BUG" warning that would appear when a controller chooses
+      the first hop for a circuit, and that circuit completes. Fixes bug
+      40285; bugfix on 0.3.2.1-alpha.
+
+  o Minor bugfixes (onion service, client, memory leak, backport from 0.4.6.3-rc):
+    - Fix a bug where an expired cached descriptor could get overwritten
+      with a new one without freeing it, leading to a memory leak. Fixes
+      bug 40356; bugfix on 0.3.5.1-alpha.
+
+  o Minor bugfixes (testing, BSD, backport from 0.4.6.2-alpha):
+    - Fix pattern-matching errors when patterns expand to invalid paths
+      on BSD systems. Fixes bug 40318; bugfix on 0.4.5.1-alpha. Patch by
+      Daniel Pinto.
