+ `notmuch address` has gained a new `--deduplicate` option to specify
+ how the results should be deduplicated, if at all. The alternatives
+ are `no` (do not deduplicate, useful for processing the results with
+ external tools), `mailbox` (deduplicate based on the full, case
+ sensitive name and email address), and `address` (deduplicate based
+ on the case insensitive address part). See the `notmuch-address`
+ manual page for further information.
