+Notmuch 0.18 (UNRELEASED)
+=========================
+
+Command-Line Interface
+----------------------
+
+`notmuch dump` now defaults to `batch-tag` format.
+
+ The old format is still available with `--format=sup`.
+
+`notmuch new` has a --quiet option
+
+ This option suppresses the progress and summary reports.
+
+Emacs Interface

+Changed format for saved searches
-Notmuch 0.17 (UNRELEASED)
+ The format for `notmuch-saved-searches` has changed, but old style
+ saved searches are still supported. The new style means that a saved
+ search can store the desired sort order for the search, and it can
+ store a separate query to use for generating the count notmuch
+ shows.
+
+ The variable is fully customizable and any configuration done
+ through customize should *just work*, with the additional options
+ mentioned above. For manual customization see the documentation for
+ `notmuch-saved-searches`.
+
+ IMPORTANT: a new style notmuch-saved-searches variable will break
+ previous versions of notmuch-emacs (even search will not work); to
+ fix remove the customization for notmuch-saved-searches.
+
+ If you have a custom saved search sort function (not unsorted or
+ alphabetical) then the sort function will need to be
+ modified. Replacing (car saved-search) by (notmuch-saved-search-get
+ saved-search :name) and (cdr saved-search) by
+ (notmuch-saved-search-get saved-search :query) should be sufficient.
+
+Bug fix for saved searches with newlines in them
+
+ Split lines confuse `notmuch count --batch`, so we remove embedded
+ newlines before calling notmuch count.

=========================
+Incompatible change in SHA1 computation
+---------------------------------------
+
+Previously on big endian architectures like sparc and powerpc the
+computation of SHA1 hashes was incorrect. This meant that messages
+with overlong or missing message-ids were given different computed
+message-ids than on more common little endian architectures like i386
+and amd64. If you use notmuch on a big endian architecture, you are
+strongly advised to make a backup of your tags using `notmuch dump`
+before this upgrade. You can locate the affected files using something
+like:
+
+ notmuch dump | \
+ awk '/^notmuch-sha1-[0-9a-f]{40} / \
+ {system("notmuch search --exclude=false --output=files id:" $1)}'
+
Command-Line Interface
----------------------
RFC 2047-encodes the headers, making the output a valid RFC 2822
message. The JSON/sexp format is unchanged.
+`notmuch compact` command
+
+ The new `compact` command exposes Xapian's compaction
+ functionality through a more convenient interface than
+ `xapian-compact`. `notmuch compact` will compact the database to a
+ temporary location, optionally backup the original database, and
+ move the compacted database into place.
+
Emacs Interface
---------------
+`notmuch-tree` (formerly `notmuch-pick`) has been added to mainline
+
+ `notmuch-tree` is a threaded message view for the emacs
+ interface. Each message is one line in the results and the thread
+ structure is shown using UTF-8 box drawing characters (similar to
+ Mutt's threaded view). It comes between search and show in terms of
+ amount of output and can be useful for viewing both single threads
+ and multiple threads.
+
+ Using `notmuch-tree`
+
+ The main key entries to notmuch tree are
+
+ 'z' enter a query to view using notmuch tree (works in hello,
+ search, show and tree mode itself)
+
+ 'Z' view the current query in tree notmuch tree (works from search
+ and show)
+
+ Once in tree mode, keybindings are mostly in line with the rest of
+ notmuch and are all viewable with '?' as usual.
+
+ Customising `notmuch-tree`
+
+ `notmuch-tree` has several customisation variables. The most
+ significant is the first notmuch-tree-show-out which determines the
+ behaviour when selecting a message (with RET) in tree view. By
+ default tree view uses a split window showing the single message in
+ the bottom pane. However, if this option is set then it views the
+ whole thread in the complete window jumping to the selected message
+ in the thread. In either case command-prefix selects the other option.
+
Tagging threads in search is now race-free
Previously, adding or removing a tag from a thread in a search
`notmuch-help` (usually bound to "?"). The bindings listed by
`notmuch-help` also now include descriptions of prefixed commands.
+Quote replies as they are displayed in show view
+
+ We now render the parts for reply quoting the same way they are
+ rendered for show. At this time, the notable change is that replies
+ to text/calendar are now pretty instead of raw vcalendar.
+
Fixed inconsistent use of configured search order
All ways of interactively invoking search now honor the value of
changes or a space-separated string of tag changes. The latter is
no longer supported and the function now returns nothing.
+Fixed `notmuch-reply` putting reply in primary selection
+
+ On emacs 24 notmuch-reply used to put the cited text into the
+ primary selection (which could lead to inadvertently pasting this
+ cited text elsewhere). Now the primary-selection is not changed.
+
+Fixed `notmuch-show` invisible part handling
+
+ In some obscure cases part buttons and invisibility had strange
+ interactions: in particular, the default action for some parts gave
+ the wrong action. This has been fixed.
+
+Fixed `notmuch-show` attachment viewers and stderr
+
+ In emacs 24.3+ viewing an attachment could cause spurious text to
+ appear in the show buffer (any stderr or stdout the viewer
+ produced). By default this output is now discarded. For debugging,
+ setting `notmuch-show-attachment-debug` causes notmuch to keep the
+ viewer's stderr and stdout in a separate buffer.
+
+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.
+
+Vim Interface
+-------------
+
+ It is now possible to compose new messages in the Vim interface, as
+ opposed reply to existing messages. There is also support for
+ going straight to a search (bypassing the folders view).
