+Changes in version 0.3.5.14 - 2021-03-16
+  Tor 0.3.5.14 backports fixes for two important denial-of-service bugs
+  in earlier versions of Tor.
+
+  One of these vulnerabilities (TROVE-2021-001) would allow an attacker
+  who can send directory data to a Tor instance to force that Tor
+  instance to consume huge amounts of CPU. This is easiest to exploit
+  against authorities, since anybody can upload to them, but directory
+  caches could also exploit this vulnerability against relays or clients
+  when they download. The other vulnerability (TROVE-2021-002) only
+  affects directory authorities, and would allow an attacker to remotely
+  crash the authority with an assertion failure. Patches have already
+  been provided to the authority operators, to help ensure
+  network stability.
+
+  We recommend that everybody upgrade to one of the releases that fixes
+  these issues (0.3.5.14, 0.4.4.8, or 0.4.5.7) as they become available
+  to you.
+
+  This release also updates our GeoIP data source, and fixes a
+  compatibility issue.
+
+  o Major bugfixes (security, denial of service, backport from 0.4.5.7):
+    - Disable the dump_desc() function that we used to dump unparseable
+      information to disk. It was called incorrectly in several places,
+      in a way that could lead to excessive CPU usage. Fixes bug 40286;
+      bugfix on 0.2.2.1-alpha. This bug is also tracked as TROVE-2021-
+      001 and CVE-2021-28089.
+    - Fix a bug in appending detached signatures to a pending consensus
+      document that could be used to crash a directory authority. Fixes
+      bug 40316; bugfix on 0.2.2.6-alpha. Tracked as TROVE-2021-002
+      and CVE-2021-28090.
+
+  o Minor features (geoip data, backport from 0.4.5.7):
+    - We have switched geoip data sources. Previously we shipped IP-to-
+      country mappings from Maxmind's GeoLite2, but in 2019 they changed
+      their licensing terms, so we were unable to update them after that
+      point. We now ship geoip files based on the IPFire Location
+      Database instead. (See https://location.ipfire.org/ for more
+      information). This release updates our geoip files to match the
+      IPFire Location Database as retrieved on 2021/03/12. Closes
+      ticket 40224.
+
+  o Removed features (mallinfo deprecated, backport from 0.4.5.7):
+    - Remove mallinfo() usage entirely. Libc 2.33+ now deprecates it.
+      Closes ticket 40309.
+
+
 Changes in version 0.3.5.13 - 2020-02-03
   Tor 0.3.5.13 backports numerous bugfixes from later releases,
   including one that made v3 onion services more susceptible to
