+Notmuch 0.18~rc0 (2014-04-22)
+=============================
+
+Overview
+--------
+
+This new release includes some enhancements to searching for messages
+by filesystem location (`folder:` and `path:` prefixes under *General*
+below). Saved searches in *Emacs* have also been enhanced to allow
+distinct search orders for each one. Another enhancement to the
+*Emacs* interface is that replies to encrypted messages are now
+encrypted, reducing the risk of unintentional information disclosure.
+The default dump output format has changed to the more robust
+`batch-tag` format. The previously deprecated parsing of single
+message mboxes has been removed. For detailed release notes, see
+below.
-Notmuch 0.17 (UNRELEASED)
+General
+-------
+
+The `folder:` search prefix now requires an exact match
+
+ The `folder:` prefix has been changed to search for email messages
+ by the exact, case sensitive maildir or MH folder name. The new
+ behaviour allows for more accurate mail folder based searches, and
+ should lead to less surprising results than the old behaviour. Users
+ are advised to see the `notmuch-search-terms` manual page for
+ details, and review how the change affects their existing `folder:`
+ searches.
+
+There is a new `path:` search prefix.
+
+ The new `path:` search prefix complements the `folder:` prefix. The
+ `path:` prefix searches for email messages that are in particular
+ directories within the mail store, optionally recursively using a
+ special syntax. See the `notmuch-search-terms` manual page for
+ details.
+
+Notmuch database upgrade due to `folder:` and `path:` changes
+
+ The above mentioned changes to the `folder:` prefix and the addition
+ of `path:` prefix require a Notmuch database upgrade. This will be
+ done automatically, without prompting on the next time `notmuch new`
+ is run after the upgrade. The upgrade is not reversible, and the
+ upgraded database will not be readable by older versions of
+ Notmuch. As a safeguard, a database dump will be created in the
+ `.notmuch` directory before upgrading.
+
+Library changes
+---------------
+
+Notmuch database upgrade
+
+ The libnotmuch consumers are reminded to handle database upgrades
+ properly, either by relying on running `notmuch new`, or checking
+ `notmuch_database_needs_upgrade()` and calling
+ `notmuch_database_upgrade()` as necessary. This has always been the
+ case, but in practise there have been no database upgrades in any
+ released version of Notmuch before now.
+
+Support for indexing mbox files has been dropped
+
+ There has never been proper support for mbox files containing
+ multiple messages, and the support for single-message mbox files has
+ been deprecated since Notmuch 0.15. The support has now been
+ dropped, and all mbox files will be rejected during indexing.
+
+Message header parsing changes
+
+ Notmuch previously had an internal parser for message headers. The
+ parser has now been dropped in favour of letting GMime parse both
+ the headers and the message MIME structure at the same pass. This is
+ mostly an internal change, but the GMime parser is stricter in its
+ interpretation of the headers. This may result in messages with
+ slightly malformed message headers being now rejected.
+
+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.
+
+`notmuch insert` respects maildir.synchronize_flags config option
+
+ Do not synchronize tags to maildir flags in `notmuch insert` if the
+ user does not want it.
+
+The commands set consistent exit status codes on failures
+
+ The cli commands now consistently set exit status of 1 on failures,
+ except where explicitly otherwise noted. The notable expections are
+ the status codes for format version mismatches for commands that
+ support formatted output.
+
+Emacs Interface
+---------------
+
+Init file
+
+ If the file pointed by new variable `notmuch-init-file` (typically
+ `~/.emacs.d/notmuch-config.el`) exists, it is loaded at the end of
+ `notmuch.el`. Users can put their personal notmuch emacs lisp based
+ configuration/customization items there instead of filling
+ `~/.emacs` with these.
+
+Changed format for saved searches
+
+ 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.
+
+The keys of `notmuch-tag-formats` are now regexps
+
+ Previously, the keys were literal strings. Customized settings of
+ `notmuch-tag-formats` will continue to work as before unless tags
+ contain regexp special characters like `.` or `*`.
+
+Changed tags are now shown in the buffer
+
+ Previously tag changes made in a buffer were shown immediately. In
+ some cases (particularly automatic tag changes like marking read)
+ this made it hard to see what had happened (e.g., whether the
+ message had been unread).
+
+ The changes are now shown explicitly in the buffer: by default
+ deleted tags are displayed with red strike-through and added tags
+ are displayed underlined in green (inverse video is used for deleted
+ tags if the terminal does not support strike-through).
+
+ The variables `notmuch-tag-deleted-formats` and
+ `notmuch-tag-added-formats`, which have the same syntax as
+ `notmuch-tag-formats`, allow this to be customized.
+
+ Setting `notmuch-tag-deleted-formats` to `'((".*" nil))` and
+ `notmuch-tag-added-formats` to `'((".*" tag))` will give the old
+ behavior of hiding deleted tags and showing added tags identically
+ to tags already present.
+
+Version variable
+
+ The new, build-time generated variable `notmuch-emacs-version` is used
+ to distinguish between notmuch cli and notmuch emacs versions.
+ The function `notmuch-hello-versions` (bound to 'v' in notmuch-hello
+ window) prints both notmuch cli and notmuch emacs versions in case
+ these differ from each other.
+ This is especially useful when using notmuch remotely.
+
+Ido-completing-read initialization in Emacs 23
+
+ `ido-completing-read` in Emacs 23 versions 1 through 3 freezes unless
+ it is initialized. Defadvice-based *Ido* initialization is defined
+ for these Emacs versions.
+
+Bug fix for saved searches with newlines in them
+
+ Split lines confuse `notmuch count --batch`, so we remove embedded
+ newlines before calling notmuch count.
+
+Bug fixes for sender identities
+
+ Previously, Emacs would rewrite some sender identities in unexpected
+ and undesirable ways. Now it will use identities exactly as
+ configured in `notmuch-identities`.
+
+Replies to encrypted messages will be encrypted by default
+
+ In the interest of maintaining confidentiality of communications,
+ the Notmuch Emacs interface now automatically adds the mml tag to
+ encrypt replies to encrypted messages. This should make it less
+ likely to accidentally reply to encrypted messages in plain text.
+
+nmbug
+-----
+
+nmbug adds a `clone` command for setting up the initial repository and
+uses `@{upstream}` instead of `FETCH_HEAD` to track upstream changes.
+
+ The `@{upstream}` change reduces ambiguity when fetching multiple
+ branches, but requires existing users update their `NMBGIT`
+ repository (usually `~/.nmbug`) to distinguish between local and
+ remote-tracking branches. The easiest way to do this is:
+
+ 1. If you have any purely local commits (i.e. they aren't in the
+ nmbug repository on nmbug.tethera.net), push them to a remote
+ repository. We'll restore them from the backup in step 4.
+ 2. Remove your `NMBGIT` repository (e.g. `mv .nmbug .nmbug.bak`).
+ 3. Use the new `clone` command to create a fresh clone:
+
+ nmbug clone http://nmbug.tethera.net/git/nmbug-tags.git
+
+ 4. If you had local commits in step 1, add a remote for that
+ repository and fetch them into the new repository.

=========================
+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).
