-  o Minor bugfixes (directory mirrors):
-    - Allow relays to use directory mirrors without a DirPort: these relays
-      need to be contacted over their ORPorts using a begindir connection.
-      Fixes bug 20711; bugfix on 0.2.8.2-alpha.
-    - Clarify the message logged when a remote relay is unexpectedly missing
-      an ORPort or DirPort: users were confusing this with a local port.

-  o Major bugfixes (HTTP, parsing):
-    - When parsing a malformed content-length field from an HTTP message,
-      do not read off the end of the buffer. This bug was a potential
-      remote denial-of-service attack against Tor clients and relays.
-      A workaround was released in October 2016, which prevents this
-      bug from crashing Tor. This is a fix for the underlying issue,
-      which should no longer matter (if you applied the earlier patch).
-      Fixes bug 20894; bugfix on 0.2.0.16-alpha. Bug found by fuzzing
-      using AFL (http://lcamtuf.coredump.cx/afl/).
