+=========================
+
+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).
+
+Improved `notmuch new` performance for unchanged folders
+
+ `notmuch new` now skips over unchanged folders more efficiently,
+ which can substantially improve the performance of checking for new
+ mail in some situations (like NFS-mounted Maildirs).
+
+`notmuch reply --format=text` RFC 2047-encodes headers
+
+ Previously, this used a mix of standard MIME encoding for the reply
+ body and UTF-8 for the headers. Now, the text format reply template
+ RFC 2047-encodes the headers, making the output a valid RFC 2822
+ message. The JSON/sexp format is unchanged.
+
+Emacs Interface
+---------------
+
+Tagging threads in search is now race-free
+
+ Previously, adding or removing a tag from a thread in a search
+ buffer would affect messages that had arrived after the search was
+ performed, resulting in, for example, archiving messages that were
+ never seen. Tagging now affects only the messages that were in the
+ thread when the search was performed.
+
+`notmuch-hello` refreshes when switching to the buffer
+
+ The hello buffer now refreshes whenever you switch to the buffer,
+ regardless of how you get there. You can disable automatic
+ refreshing by customizing `notmuch-hello-auto-refresh`.
+
+Specific mini-buffer prompts for tagging operations
+
+ When entering tags to add or remove, the mini-buffer prompt now
+ indicates what operation will be performed (e.g., "Tag thread", "Tag
+ message", etc).
+
+Built-in help improvements
+
+ Documentation for many commands has been improved, as displayed by
+ `notmuch-help` (usually bound to "?"). The bindings listed by
+ `notmuch-help` also now include descriptions of prefixed commands.
+
+Fixed inconsistent use of configured search order
+
+ All ways of interactively invoking search now honor the value of
+ `notmuch-search-oldest-first`.
+
+Common keymap for notmuch-wide bindings
+
+ Several key bindings have been moved from mode-specific keymaps to
+ the single `notmuch-common-keymap`, which is inherited by each
+ notmuch mode. If you've customized your key bindings, you may want
+ to move some of them to the common keymap.
+
+The `notmuch-tag` function now requires a list of tag changes
+
+ For users who have scripted the Emacs interface: the `notmuch-tag`
+ API has changed. Previously, it accepted either a list of tag
+ changes or a space-separated string of tag changes. The latter is
+ no longer supported and the function now returns nothing.
+
+Fixed `notmuch-mua-reply` point placement when signature involved
+
+ By restricting cursor movement to body section for cursor placement
+ after signature is inserted, the cursor cannot "leak" to header
+ section anymore. Now inserted citation content will definitely go to
+ the body part of the message.
