        - Update README.man with clearer text.
+       - Merge #1337: 0 TTL cached replies and some TTL behavior changes.
+       - TTL change: Cached records that reach TTL 0 are expired.
+       - TTL change: TTL 0 upstream answers are no longer cached by
+          cachedb, as they should.
+       - TTL change: 'serve-expired-reply-ttl' is now capped by the original
+         TTL value of the record to try and make some sense when replying
+         with expired records.
+       - TTL change: TTL decoding was updated to adhere to RFC8767 section 4
+         where a 'set high-order bit' means the value is positive instead of
+         0.
