+\r
+This patch series changes notmuch-mutt to use the new built-in\r
+--duplicate flag for removing duplicates by message-id.\r
+\r
+This should speed up duplicate removal, since we no longer need to scan\r
+and compute sha sums. However, it does now allow search results to be\r
+hidden in the event of accidental or malicious message-id re-use.\r
+\r
+The duplicate removal is optional, but is currently enabled by default\r
+in the distributed /etc/Muttrc.d/notmuch-mutt.rc file.\r
+\r
+Please don't hesitate to comment if this change is too controversial!\r
+\r
+Thank you,\r
+\r
