   o Major bugfixes (bridges):
-    - When the same bridge is configured multiple times at different
-      address:port combinations (but with the same identity), treat
-      those bridge instances as separate guards. This allows clients to
-      configure the same bridge with multiple pluggable transports, once
-      again. Fixes bug 21027; bugfix on 0.3.0.1-alpha.

   o Major bugfixes (hidden service directory v3):
-    - When a descriptor lookup was done and it was not found in the
-      directory cache, it would crash on a NULL pointer instead of
-      returning the 404 code back to the client like it was suppose to.
-      Fixes bug 21471; bugfixes on tor-0.3.0.1-alpha.
+    - Stop crashing on a failed v3 hidden service descriptor lookup
+      failure. Fixes bug 21471; bugfixes on tor-0.3.0.1-alpha.

+  o Major bugfixes (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/).

+  o Minor feature (protocol versioning):
     - Add new protocol version for proposal 224. HSIntro now advertises
       version "3-4" and HSDir version "1-2". Fixes ticket 20656.

+  o Minor features (directory authorities):
     - Directory authorities now reject descriptors that claim to be
       malformed versions of Tor. Helps prevent exploitation of

       instance of bug 21007; bugfix on 0.3.0.1-alpha.
 
   o Minor bugfixes (hidden service):
-    - When encoding a legacy ESTABLISH_INTRO cell, we were using the
-      sizeof() on a pointer instead of real size of the destination
-      buffer leading to an overflow passing an enormous value to the
-      signing digest function. Fortunately, that value was only used to
-      make sure the destination buffer length was big enough for the key
-      size and in this case it was. Fixes bug 21553; bugfix
-      on 0.3.0.1-alpha.
+    - Pass correct buffer length when encoding legacy ESTABLISH_INTRO
+      cells. Previously, we were using sizeof() on a pointer, instead of
+      the real destination buffer. Fortunately, that value was only used
+      to double-check that there was enough room--which was already
+      enforced elsewhere. Fixes bug 21553; bugfix on 0.3.0.1-alpha.
 
   o Minor bugfixes (testing):

     - Rename "make fuzz" to "make test-fuzz-corpora", since it doesn't
       actually fuzz anything. Fixes bug 21447; bugfix on 0.3.0.3-alpha.
     - Use bash in src/test/test-network.sh. This ensures we reliably
       call chutney's newer tools/test-network.sh when available. Fixes
       bug 21562; bugfix on 0.2.9.1-alpha.
