+Command-Line Interface
+----------------------
+
+New options to better support handling duplicate messages
+
+ If more than one message file is associated with a message-id,
+ `notmuch search --output=files` will print all of them. A new
+ `--duplicate=N` option can be used to specify which duplicate to
+ print for each message.
+
+ `notmuch count` now supports `--output=files` option to output the
+ number of files associated with matching messages. This may be
+ bigger than the number of matching messages due to duplicates
+ (i.e. multiple files having the same message-id).
