1 Notmuch 0.12 (2012-xx-xx)
2 =========================
9 "notmuch reply" has gained the ability to create a reply template
10 for replying just to the sender of the message, in addition to reply
11 to all. The feature is available through the new command line option
12 --reply-to=(all|sender).
16 Tags can be automatically excluded from search results by adding them
17 to the new 'search.exclude_tags' option in the Notmuch config file.
19 This behaviour can be overridden by explicitly including an excluded
20 tag in your query, for example:
22 notmuch search $your_query and tag:$excluded_tag
24 Existing users will probably want to run "notmuch setup" again to add
25 the new well-commented [search] section to the configuration file.
27 For new configurations, accepting the default setting will cause the
28 tags "deleted" and "spam" to be excluded, equivalent to running:
30 notmuch config set search.exclude_tags deleted spam
32 Mail store folder/file ignore
34 A new configuration option, `new.ignore`, lets users specify a
35 ;-separated list of file and directory names that will not be
36 searched for messages by "notmuch new".
43 The Emacs interface has, with the new CLI support, gained the
44 ability to reply to sender in addition to reply to all. In both show
45 and search modes, 'r' has been bound to reply to sender, replacing
46 reply to all, which now has key binding 'R'.
48 More flexible and consistent tagging operations
50 All tagging operations ("+", "-", "*") now accept multiple tags with
51 "+" or "-" prefix, like "*" operation in notmuch-search view before.
53 "*" operation (`notmuch-show-tag-all') is now available in
56 `Notmuch-show-{add,remove}-tag' functions no longer accept tag
57 argument, `notmuch-show-tag-message' should be used instead. Custom
58 bindings using these functions should be updated, e.g.:
60 (notmuch-show-remove-tag "unread")
64 (notmuch-show-tag-message "-unread")
71 notmuch_query_add_tag_exclude supports the new tag exclusion
74 Python bindings changes
75 -----------------------
77 Python 3.2 compatibility
79 The python bindings are now compatible with both python 2.5+ and 3.2.
84 Compatibility with GMime 2.6
86 It is now possible to build notmuch against both GMime 2.4 and 2.6.
87 However, a bug in current GMime 2.6 causes notmuch not to report
88 signatures where the signer key is unavailable (GNOME bug 668085).
90 Notmuch 0.11.1 (2012-02-03)
91 ===========================
96 Fix error handling in python bindings.
98 The python bindings in 0.11 failed to detect NULL pointers being
99 returned from libnotmuch functions and thus failed to raise
100 exceptions to indicate the error condition. Any subsequent calls
101 into libnotmuch caused segmentation faults.
103 Quote MML tags in replies
105 MML tags are text codes that Emacs uses to indicate attachments
106 (among other things) in messages being composed. The Emacs
107 interface did not quote MML tags in the quoted text of a reply.
108 User could be tricked into replying to a maliciously formatted
109 message and not editing out the MML tags from the quoted text. This
110 could lead to files from the user's machine being attached to the
111 outgoing message. The Emacs interface now quotes these tags in
112 reply text, so that they do not effect outgoing messages.
114 Notmuch 0.11 (2012-01-13)
115 =========================
117 Command-Line Interface
118 ----------------------
122 Hooks have been introduced to notmuch. Hooks are scripts that notmuch
123 invokes before and after certain actions. Initially, "notmuch new"
124 supports "pre-new" and "post-new" hooks that are run before and after
125 importing new messages into the database.
127 notmuch reply --decrypt bugfix
129 The "notmuch reply" command with --decrypt argument had a rarely
130 occurring bug that caused an encrypted message not to be decrypted
131 sometimes. This is now fixed.
136 Automatic tag query optimization
138 "notmuch tag" now automatically optimizes the user's query to
139 exclude messages whose tags won't change. In the past, we've
140 suggested that people do this by hand; this is no longer necessary.
142 Don't sort messages when creating a dump file
144 This speeds up tag dumps considerably, without any loss of
145 information. To replicate the old behavior of sorted output (for
146 example to compare two dump files), one can use e.g. sort(1).
151 Reduction of memory leaks
153 Two memory leaks when searching and showing messages were identified
154 and fixed in this release.
161 notmuch-show-advance (bound to the spacebar in notmuch-show-mode) had
162 a bug that caused it to always jump to the next message, even if it
163 should have scrolled down to show more of the current message instead.
166 Support "notmuch new" as a notmuch-poll-script
168 It's now possible to use "notmuch new" as a notmuch-poll-script
169 directly. This is also the new default. This allows taking better
170 advantage of the "notmuch new" hooks from emacs without intermediate
173 Improvements in saved search management
175 New saved searches are now appended to the list of saved searches,
176 not inserted in front. It's also possible to define a sort function
177 for displaying saved searches; alphabetical sort is provided.
179 Hooks for notmuch-hello
181 Two new hooks have been added: "notmuch-hello-mode-hook" (called after
182 entering notmuch-hello-mode) and "notmuch-hello-refresh-hook" (called
183 after updating a notmuch-hello buffer).
185 New face for crypto parts headers
187 Crypto parts used to be displayed with a hardcoded color. A new face
188 has been introduced to fix this: notmuch-crypto-part-header. It
189 defaults to the same value as before, but can be customized to match
192 Use space as default thousands separator
194 Large numbers in notmuch-hello are now displayed using a space as
195 thousands separator (e.g. "123 456" instead of "123,456"). This can be
196 changed by customizing "notmuch-hello-thousands-separator".
198 Call notmuch-show instead of notmuch-search when clicking on
199 buttonized id: links.
201 New function notmuch-show-advance
203 This new function advances through just the current thread, and is
204 less invasive than notmuch-show-advance-and-archive. It can easily
205 be bound to SPC with:
207 (define-key notmuch-show-mode-map " " 'notmuch-show-advance)
209 Various performance improvements.
214 The tool contrib/notmuch-deliver helps with initial delivery and
215 tagging of mail (replacing running notmuch new).
218 Notmuch 0.10.2 (2011-12-04)
219 ===========================
224 Fix crash in python bindings.
226 The python bindings did not call g_type_init, which caused crashes
227 for some, but not all users.
229 Notmuch 0.10.1 (2011-11-25)
230 ===========================
237 Argument processing changes in 0.10 introduced a bug where "notmuch
238 --help" crashed while "notmuch help" worked fine. This is fixed in
241 Notmuch 0.10 (2011-11-23)
242 =========================
244 New build and testing features
245 ------------------------------
247 Emacs tests are now done in dtach. This means that dtach is now
248 needed to run the notmuch test suite, at least until the checking for
249 prerequisites is improved.
251 Full test coverage of the stashing feature in Emacs.
253 New command-line features
254 -------------------------
256 Add "notmuch restore --accumulate" option
258 The --accumulate switch causes the union of the existing and new tags to be
259 applied, instead of replacing each message's tags as they are read in from
262 Add search terms to "notmuch dump"
264 The dump command now takes an optional search term much like notmuch
265 search/show/tag. The output file argument of dump is deprecated in
266 favour of using stdout.
268 Add "notmuch search" --offset and --limit options
270 The search command now takes options --offset=[-]N and --limit=N to limit
271 the number of results shown.
273 Add "notmuch count --output" option
275 The count command is now capable of counting threads in addition to
276 messages. This is selected using the new --output=(threads|messages) option.
278 New emacs UI features
279 ---------------------
281 Add tab-completion for notmuch-search and notmuch-search-filter
283 These functions now support completion tags for query parts
284 starting with "tag:".
286 Turn "id:MSG-ID" links into buttons associated with notmuch searches
288 Text of the form "id:MSG-ID" in mails is now a clickable button that
289 opens a notmuch search for the given message id.
291 Add keybinding ('c I') for stashing Message-ID's without an id: prefix
293 Reduces manual labour when stashing them for use outside notmuch.
295 Do not query on notmuch-search exit
297 It is harmless to kill the external notmuch process, so the user
298 is no longer interrogated when they interrupt a search.
303 Emacs now constructs large search buffers more efficiently
305 Search avoids opening and parsing message files
307 We now store more information in the database so search no longer
308 has to open every message file to get basic headers. This can
309 improve search speed by as much as 10X, but taking advantage of this
310 requires a database rebuild:
312 notmuch dump > notmuch.dump
313 # Backup, then remove notmuch database ($MAIL/.notmuch)
315 notmuch restore notmuch.dump
317 New collection of add-on tools
318 ------------------------------
320 The source directory "contrib" contains tools built on notmuch. These
321 tools are not part of notmuch, and you should check their individual
322 licenses. Feel free to report problems with them to the notmuch
325 nmbug - share tags with a given prefix
327 nmbug helps maintain a git repo containing all tags with a given
328 prefix (by default "notmuch::"). Tags can be shared by commiting
329 them to git in one location and restoring in another.
331 Notmuch 0.9 (2011-10-01)
332 ========================
334 New, general features
335 ---------------------
337 Correct handling of interruptions during "notmuch new"
339 "notmuch new" now operates as a series of small, self-consistent
340 transactions, so it can correctly resume after an interruption or
341 crash. Previously, interruption could lose existing tags, fail to
342 detect messages on resume, or leave the database in a state
343 temporarily or permanently inconsistent with the mail store.
350 notmuch_database_begin_atomic and notmuch_database_end_atomic allow
351 multiple database operations to be performed atomically.
353 notmuch_database_find_message_by_filename does exactly what it says.
357 notmuch_database_find_message (and n_d_f_m_by_filename) now return
358 a status indicator and uses an output parameter for the
359 message. This change required changing the SONAME of libnotmuch to
362 Python bindings changes
363 -----------------------
365 - Re-encode python unicode objects to utf-8 before passing back to
367 - Support Database().begin_atomic()/end_atomic()
368 - Support Database().find_message_by_filename()
369 NB! This needs a db opened in READ-WRITE mode currently, or it will crash
370 the python process. The is a limitation (=bug) of the underlying libnotmuch.
371 - Fixes where we would not throw NotmuchErrors when we should (Justus Winter)
372 - Update for n_d_find_message* API changes (see above).
374 Ruby bindings changes
375 ---------------------
377 - Wrap new library functions notmuch_database_{begin,end}_atomic.
378 - Add new exception Notmuch::UnbalancedAtomicError.
379 - Rename destroy to destroy! according to Ruby naming conventions.
380 - Update for n_d_find_message* API changes (see above).
385 * Add gpg callback to crypto sigstatus buttons to retrieve/refresh
387 * Add notmuch-show-refresh-view function (and corresponding binding)
388 to refresh the view of a notmuch-show buffer.
390 Reply formatting cleanup
391 ------------------------
393 "notmuch reply" no longer includes notification that non-leafnode
394 MIME parts are being suppressed.
396 Notmuch 0.8 (2011-09-10)
397 ========================
399 Improved handling of message/rfc822 parts
401 Both in the CLI and the emacs interface. Output of rfc822 parts now
402 includes the primary headers, as well as the body and all subparts.
403 Output of the completely raw rfc822-formatted message, including all
404 headers, is unfortunately not yet supported (but hopefully will be
407 Improved Build system portability
409 Certain parts of the shell script generating notmuch.sym were
410 specific to the GNU versions of sed and nm. The new version should
411 be more portable to e.g. OpenBSD.
413 Documentation update for Ruby bindings
415 Added documentation, typo fixes, and improved support for rdoc.
417 Unicode, iterator, PEP8 changes for python bindings
419 - PEP8 (code formatting) changes for python files.
420 - Remove Tags.__len__ ; see 0.6 release notes for motivation.
421 - Decode headers as UTF8, encode (unicode) database paths as UTF8.
423 Notmuch 0.7 (2011-08-01)
424 ========================
426 Vim interface improvements
427 --------------------------
429 Jason Woofenden provided a number of bug fixes for the Vim interface
431 * fix citation/signature fold lengths
432 * fix cig/cit parsing within multipart/*
433 * fix on-screen instructions for show-signature
434 * fix from list reformatting in search view
435 * fix space key: now archives (did opposite)
437 Uwe Kleine-König contributed
439 * use full path for sendmail/doc fix
440 * fix compose temp file name
442 Python Bindings changes
443 -----------------------
445 Sebastian Spaeth contributed two changes related to unicode and UTF8:
447 * message tags are now explicitly unicode
448 * query string is encoded as a UTF8 byte string
450 Build-System improvements
451 ------------------------
453 Generate notmuch.sym after the relevant object files
455 This fixes a bug in parallel building. Thanks to Thomas Jost for the
458 Notmuch 0.6.1 (2011-07-17)
459 ==========================
464 Re-export Xapian exception typeinfo symbols.
466 It turned out our aggressive symbol hiding caused problems for
467 people running gcc 4.4.5.
469 Notmuch 0.6 (2011-07-01)
470 =======================
471 New, general features
472 ---------------------
473 Folder-based searching
475 Notmuch queries can now include a search term to match the
476 directories in which mail files are stored (within the mail
477 storage). The syntax is as follows:
481 For example, one might use things such as:
487 to match any path containing a directory "spam", "work/todo", or
488 containing a directory starting with "2011-", respectively.
490 This feature is particularly useful for users of delivery-agent
491 software (such as procmail or maildrop) that is filtering mail and
492 delivering it to particular folders, or users of systems such as
493 Gmail that use filesystem directories to indicate message tags.
495 NOTE: Only messages that are newly indexed with this version of
496 notmuch will be searchable with folder: terms. In order to enable
497 this feature for all mail, the entire notmuch index will need to be
500 notmuch dump > notmuch.dump
501 # Backup, then remove notmuch database ($MAIL/.notmuch)
503 notmuch restore notmuch.dump
507 Both the command line interface and the emacs-interface have new
508 support for PGP/MIME, detailed below. Thanks to Daniel Kahn Gillmor
509 and Jameson Graef Rollins for making this happen.
511 New, automatic tags: "signed" and "encrypted"
513 These tags will automatically be applied to messages containing
514 multipart/signed and multipart/encrypted parts.
516 NOTE: Only messages that are newly indexed with this version of
517 notmuch will receive these tags.
519 New command-line features
520 -------------------------
521 Add new "notmuch show --verify" option for signature verification
523 This option instruct notmuch to verify the signature of
524 PGP/MIME-signed parts.
526 Add new "notmuch show --decrypt" and "notmuch reply --decrypt" options
528 This option instructs notmuch to decrypt PGP/MIME-encrypted parts.
529 Note that this feature currently requires gpg-agent and a passphrase entry
530 tool (e.g. pinentry-gtk or pinentry-curses).
532 Proper nesting of multipart parts in "notmuch show" output
534 MIME parts are now display with proper nesting to reflect original
535 MIME hierarchy of a message. This allows clients to correctly
536 analyze the MIME structure, (such as, for example, determining to
537 which parts a signature part applies).
539 Add new "notmuch show --part" option
541 This is a replacement for the older "notmuch part" command, (which
542 is now deprecated—it should still work as always, but is no longer
543 documented). Putting part output under "notmuch show" allows for all
544 of the "notmuch show" options to be applied when extracting a single
545 part, (such as --format=json for extracting a message part with JSON
548 Deprecate "notmuch search-tags", (in favor of "notmuch search --output=tags *")
550 The "notmuch search-tags" sub-command has been redundant since the
551 addition of the --output=tags option to "notmuch search". We now
552 make that more clear by deprecating "notmuch search-tags", (dropping
553 it from the documentation). We do continue to support the old syntax
554 by translating it internally to the new call.
556 Performance improvements
557 ------------------------
558 Faster searches (by doing fewer searches to construct threads)
560 Whenever a user asks for search results as threads, notmuch first
561 performs a search for messages matching the query, then performs
562 additional searches to find other messages in the resulting threads.
564 Removing inefficiencies and redundancies in these secondary searches
565 results in a measured speedups of 1.5x for a typical search.
567 Faster searches (by doing fewer passes to gather message data)
569 Optimizing Xapian data access patterns (using a single pass to get
570 all message-document data rather than a pass for each data type)
571 results in a measured speedup of 1.7x for a typical search.
573 The benefits of this optimization combine with the preceding
574 optimization. With both in place, Austin Clements measured a speedup
575 of 2.5x for a search of all messages in his inbox (was 4.5s, now
576 1.8s). Thanks, Austin!
578 Faster initial indexing
580 More efficient indexing of new messages results in a measured
581 speedup of 1.4x for the initial indexing of 3 GB of mail (1h 14m
582 rather than 1h 46m). Thanks to Austin Clements and Michal Sojka.
584 Make "notmuch new" faster for unchanged directories
586 Optimizing to not do any further examinations of sub-directories
587 when the filesystem indicates that a directory is unchanged from the
588 last "notmuch new" results in measured speedups of 8.5 for the "No
589 new mail" case, (was 0.77s, now 0.09s). Thanks to Karel Zak.
591 New emacs-interface features
592 ----------------------------
594 Support for PGP/MIME (GnuPG)
596 Automatically indicate validity of signatures for multipart/signed
597 messages. Automatically display decrypted content for
598 multipart/encrypted messages. See the emacs variable
599 notmuch-crypto-process-mime for more information. Note that this
600 needs gpg-agent and a pinentry tool just as the command line tools.
601 Also note there is no support SMIME yet.
603 Output of pipe command is now displayed if pipe command fails
605 This is extremely useful in the common use case of piping a patch to
606 "git am". If git fails to cleanly merge the patch the error messages
607 from the failed merge are now clearly displayed to the user, (where
608 previously they were silently hidden from the user).
610 User-selectable From address
612 A user can choose which configured email addresses should be used as
613 the From address whenever composing a new message. To do so, simply
614 press C-u before the command which will open a new message. Emacs
615 will prompt for the from address to use.
617 The user can customize the "Notmuch Identities" setting in the
618 notmuch customize group in order to use addresses other than those in
619 the notmuch configuration file if desired.
621 The user can also choose to always be prompted for the from address
622 when composing a new message (without having to use C-u) by setting
623 the "Notmuch Always Prompt For Sender" option in the notmuch
626 Hiding of repeated subjects in collapsed thread view
628 In notmuch-show mode, if a collapsed message has the same subject as
629 its parent, the subject is not shown.
631 Automatic detection and hiding of original message in top-posted message
633 When a message contains a line looking something like:
635 ----- Original Message -----
637 emacs hides this and all subsequent lines as an "original message",
638 (allowing the user to click or press enter on the "original message"
639 button to display it again). This makes the handling of top-posted
640 citations work much like conventional citations.
642 New hooks for running code when tags are modified
644 Some users want to perform additional actions whenever a particular
645 tag is added/removed from a message. This could be used to, for
646 example, interface with some external spam-recognition training
647 tool. To facilitate this, two new hooks are added which can be
648 modified in the following settings of the notmuch customize group:
650 Notmuch Before Tag Hook
651 Notmuch After Tag Hook
653 New optional support for hiding some multipart/alternative parts
655 Many emails are sent with redundant content within a
656 multipart/alternative group (such as a text/plain part as well as a
657 text/html part). Users can configure the setting:
659 Notmuch Show All Multipart/Alternative Parts
661 to "off" in the notmuch customize group to have the interface
662 automatically hide some part alternatives (such as text/html
663 parts). This new part hiding is not configured by default yet
664 because there's not yet a simple way to re-display such a hidden
665 part if it is not actually redundant with a displayed part.
667 Better rendering of text/x-vcalendar parts
669 These parts are now displayed in a format suitable for use with the
672 Avoid getting confused by Subject and Author fields with newline characters
674 Replacing all characters with ASCII code less than 32 with a question mark.
676 Cleaner display of From line in email messages (remove double quotes,
677 and drop "name" if it's actually just a repeat of the email address).
679 Vim interface improvements
680 --------------------------
681 Felipe Contreras provided a number of updates for the vim interface:
683 * Using sendmail directly rather than mailx,
684 * Implementing archive in show view
685 * Add support to mark as read in show and search views
686 * Add delete commands
689 Bindings improvements
690 ---------------------
691 Ruby bindings are now much more complete
693 Including QUERY.sort, QUERY.to_s, MESSAGE.maildir_flags_to_tags,
694 MESSAGE.tags_to_maildir_flags, and MESSAGE.get_filenames
696 * Python bindings have been updated and extended
697 (docs online at http://packages.python.org/notmuch/)
700 - Message().get_filenames(),
701 - Message().tags_to_maildir_flags(),Message().maildir_flags_to_tags()
702 - list(Threads()) and list(Messages) works now
704 - Message().__cmp__() and __hash__()
705 These allow, for example:
708 As well as set arithmetic on Messages():
710 s1, s2= set(msgs1), set(msgs2)
715 - len(Messages()) as it exhausted the iterator.
716 Use len(list(Messages())) or
717 Query.count_messages() to get the length.
719 Added initial Go bindings in bindings/go
721 New build-system features
722 -------------------------
723 Added support for building in a directory other than the source directory
725 This can be used with the widely-supported idiom of simply running
726 the configure script from some other directory:
733 Fix to save configure options for future, implicit runs of configure
735 When a user updates the source (such as with "git pull") calling
736 "make" may cause an automatic re-run of the configure script. When
737 this happens, the configure script will automatically be called with
738 the same options the user originally passed in the most-recent
739 manual invocation of configure.
741 New test-suite feature
742 ----------------------
743 Binary for bash for running test suite now located via PATH.
745 The notmuch test suite requires a fairly recent version of bash (>=
746 bash 4). As some systems supply an older version of bash at
747 /bin/bash, the test suite is now updated to search $PATH to locate
748 the bash binary. This allows users of systems with old /bin/bash to
749 simply install bash >= 4 somewhere on $PATH before /bin and then use
752 Support for testing output with a trailing newline.
754 Previously, some tests would fail to notice a difference in the
755 presence/absence of a trailing newline in a program output, (which
756 has led to bugs in the past). Now, carefully-written tests (using
757 test_expect_equal_file rather than test_expect_equal) will detect
758 any change in the presence/absence of a trailing newline. Many tests
759 are updated to take advantage of this.
761 Avoiding accessing user's $HOME while running test suite
763 The test suite now carefully creates its own HOME directory. This
764 allows the test suite to be run with no existing HOME directory, (as
765 some build systems apparently do), and avoids test-suite differences
766 due to configuration files in the users HOME directory.
771 Output *all* files for "notmuch search --output=files"
773 For the cases where multiple files have the same Message ID,
774 previous versions of notmuch would output only one such file. This
775 command is now fixed to correctly output all files.
777 Fixed spurious search results from "overlapped" indexing of addresses
779 This fixed a bug where a search for:
781 to:user@elsewhere.com
783 would incorrectly match a message sent:
785 To: user@example,com, someone@elsewhere.com
787 Fix --output=json when search has no results
789 A bug present since notmuch 0.4 had caused searches with no results
790 to produce an invalid json object. This is now fixed to cleanly
791 return a valid json object representing an empty array "[]" as
794 fix the automatic detection of the From address for "notmuch reply"
795 from the Received headers in some cases.
797 Fix core dump on DragonFlyBSD due to -1 return value from
798 sysconf(_SC_GETPW_R_SIZE_MAX).
800 Cleaned up several memory leaks
802 Eliminated a few, rare segmentation faults and a double-free.
804 Fix libnotmuch library to only export notmuch API functions
806 Previous release of the notmuch library also exported some Xapian
807 C++ exception type symbols. These were never part of the library
808 interface and were never intended to be exported.
810 Emacs-interface bug fixes
811 -------------------------
812 Display any unexpected output or errors from "notmuch search" invocations
814 Previously any misformatted output or trailing error messages were
815 silently ignored. This output is now clearly displayed. This fix was
816 very helpful in identifying and fixing the bug described below.
818 Fix bug where some threads would be missing from large search results
820 When a search returned a "large" number of results, the emacs
821 interface was incorrectly dropping one thread every time the output
822 of the "notmuch search" process spanned the emacs read-buffer. This
825 Avoid re-compression of .gz files (and similar) when saving attachment
827 Emacs was being too clever for its own good and trying to
828 re-compress pre-compressed .gz files when saving such attachments
829 (potentially corrupting the attachment). The emacs interface is
830 fixed to avoid this bug.
832 Fix hiding of a message when a previously-hidden citation is visible
834 Previously the citation would remain visible in this case. This is
835 fixed so that hiding a message hides all parts.
837 Notmuch 0.5 (2010-11-11)
838 ========================
839 New, general features
840 ---------------------
841 Maildir-flag synchronization
843 Notmuch now knows how to synchronize flags in maildir filenames with
844 tags in the notmuch database. The following flag/tag mappings are
853 'S' unread (added when 'S' flag is not present)
855 The synchronization occurs in both directions, (for example, adding
856 the 'S' flag to a file will cause the "unread" tag to be added, and
857 adding the "replied" tag to a message will cause the file to be
858 renamed with an 'R' flag).
860 This synchronization is enabled by default for users of the
861 command-line interface, (though only files in directories named
862 "cur" or "new" will be renamed). It can be disabled by setting the
863 new maildir.synchronize_flags option in the configuration file. For
866 notmuch config set maildir.synchronize_flags false
868 Users upgrading may also want to run "notmuch setup" once (just
869 accept the existing configuration) to get a new, nicely-commented
870 [maildir] section added to the configuration file.
872 For users of the notmuch library, the new synchronization
873 functionality is available with the following two new functions:
875 notmuch_message_maildir_flags_to_tags
876 notmuch_message_tags_to_maildir_flags
878 It is anticipated that future improvements to this support will
879 allow for safe synchronization of the 'T' flag with the "deleted"
880 tag, as well as support for custom flag/tag mappings.
884 Support for querying multiple filenames for a single message
886 It is common for the mailstore to contain multiple files with the
887 same message ID. Previously, notmuch would always hide these
888 duplicate files, (returning a single, arbitrary filename with
889 notmuch_message_get_filename).
891 With this release, library users can access all filenames for a
892 message with the new function:
894 notmuch_message_get_filenames
896 Together with notmuch_filenames_valid, notmuch_filenames_get, and
897 notmuch_filenames_move_to_next it is now possible to iterate over
898 all available filenames for a given message.
900 New command-line features
901 -------------------------
902 New "notmuch show --format=raw" for getting at original email contents
904 This new feature allows for a fully-functional email client to be
905 built on top of the notmuch command-line without needing any direct
906 access to the mail store itself.
908 For example, it's now possible to run "emacs -f notmuch" on a local
909 machine with only ssh access to the mail store/notmuch database. To
910 do this, simply set the notmuch-command variable in emacs to the
911 name of a script containing:
913 ssh user@host notmuch "$@"
915 If the ssh client has enabled connection sharing (ControlMaster
916 option in OpenSSH), the emacs interface can be quite responsive this
921 Fix "notmuch search" to print nothing when nothing matches
923 The 0.4 release had a bug in which:
925 notmuch search <expression-with-no-matches>
927 would produce a single blank line of output, (where previous
928 versions would produce no output. This fix also causes a change in
929 the --format=json output, (which would previously produce "[]" and
930 now produces nothing).
932 Emacs interface improvements
933 ----------------------------
934 Fix to allow pipe ('|') command to work when using notmuch over ssh
936 Fix count of lines in hidden signatures.
938 Omit repeated subject lines in (collapsed) thread display.
940 Display current thread subject in a header line.
942 Provide a "c i" binding to copy a thread ID from the search view.
944 Allow for notmuch-fcc-dirs to have a value of nil.
946 Also, the more complex form of notmuch-fcc-dirs now has a slightly
947 different format. It no longer has a special first-element, fallback
948 string. Instead it's now a list of cons cells where the car of each
949 cell is a regular expression to be matched against the sender
950 address, and the cdr is the name of a folder to use for an FCC. So
951 the old fallback behavior can be achieved by including a final cell
952 of (".*" . "default-fcc-folder").
954 Vim interface improvements
955 --------------------------
956 Felipe Contreras provided a number of updates for the vim interface.
958 These include optimizations, support for newer versions of vim, fixed
959 support for sending mail on modern systems, new commands, and
964 Added initial ruby bindings in bindings/ruby
966 Notmuch 0.4 (2010-11-01)
967 ========================
968 New command-line features
969 -------------------------
970 notmuch search --output=(summary|threads|messages|tags|files)
972 This new option allows for particular items to be returned from
973 notmuch searches. The "summary" option is the default and behaves
974 just as "notmuch search" has historically behaved.
976 The new option values allow for thread IDs, message IDs, lists of
977 tags, and lists of filenames to be returned from searches. It is
978 expected that this new option will be very useful in shell
979 scripts. For example:
981 for file in $(notmuch search --output=files <search-terms>); do
982 <operations-on> "$file"
985 notmuch show --format=mbox <search-specification>
987 This new option allows for the messages matching a search
988 specification to be presented as an mbox. Specifically the "mboxrd"
989 format is used which allows for reversible quoting of lines
990 beginning with "From ". A reader should remove a single '>' from the
991 beginning of all lines beginning with one or more '>' characters
992 followed by the 5 characters "From ".
994 notmuch config [get|set] <section>.<item> [value ...]
996 The new top-level "config" command allows for any value in the
997 notmuch configuration file to be queried or set to a new value. Both
998 single-valued and multi-valued items are supported, as our any
999 custom items stored in the configuration file.
1001 Avoid setting Bcc header in "notmuch reply"
1003 We decided that this was a bit heavy-handed as the actual mail
1004 user-agent should be responsible for setting any Bcc option. Also,
1005 see below for the notmuch/emacs user-agent now setting an Fcc by
1006 default rather than Bcc.
1008 New library features
1009 --------------------
1010 Add notmuch_query_get_query_string and notmuch_query_get_sort
1012 These are simply functions for querying properties of a
1013 notmuch_query_t object.
1017 Enable Fcc of all sent messages by default (to "sent" directory)
1019 All messages sent from the emacs interface will now be saved to the
1020 notmuch mail store where they will be incorporated to the database
1021 by the next "notmuch new". By default, messages are saved to the
1022 "sent" directory at the top-level of the mail store. This directory
1023 can be customized by means of the "Notmuch Fcc Dirs" option in the
1024 notmuch customize interface.
1026 Ability to all open messages in a thread to a pipe
1028 Historically, the '|' keybinding allows for piping a single message
1029 to an external command. Now, by prefixing this key with a prefix
1030 argument, (for example, by pressing "Control-U |"), all open
1031 messages in the current thread will be sent to the external command.
1033 Optional support for detecting inline patches
1035 This hook is disabled by default but can be enabled with a checkbox
1036 under "Notmuch Show Insert Text/Plain Hook" in the notmuch customize
1037 interface. It allows for inline patches to be detected and treated
1038 as if they were attachments, (with context-sensitive highlighting).
1040 Automatically tag messages as "replied" when sending a reply
1042 Messages replied to within the emacs interface will now be tagged as
1043 "replied". This feature can easily be customized to add or remove
1044 other tags as well. For example, a user might use a tag of
1045 "needs-reply" and can configure this feature to automatically remove
1046 that tag when replying. See "Notmuch Message Mark Replied" in the
1047 notmuch customize interface.
1049 Allow search-result color specifications to overlay each other
1051 For example, one tag can specify the background color of matching
1052 lines, while another can specify the foreground. With this change,
1053 both settings will now be visible simultaneously, (which was not the
1054 case in previous releases). See "Notmuch Search Line Faces" in the
1055 notmuch customize interface.
1057 Make hidden author names still available for incremental search.
1059 When there is insufficient space to display all authors of a thread
1060 in search results, the names of hidden authors are now still made
1061 available to emacs' incremental search commands. As the user
1062 searches, matching lines will temporarily expand to show the hidden
1065 New binding of Control-TAB (works like TAB in reverse)
1067 Many notmuch nodes already use TAB to navigate forward through
1068 various items allowing actions, (message headers, email attachments,
1069 etc.). The new Control-TAB binding operates similarly but in the
1072 New build-system features
1073 -------------------------
1074 Various portability fixes have been applied
1076 These include fixes for build failures on at least Solaris, FreeBSD,
1077 and Fedora systems. We're hopeful that the notmuch code base is now
1078 more portable than ever before.
1080 Arrange for libnotmuch to be found automatically after make install
1082 The notmuch build system is now careful to help the user avoid
1083 errors of the form "libnotmuch.so could not be found" immediately
1084 after installing. This support takes two forms:
1086 1. If the library is installed to a system directory,
1087 (configured in /etc/ld.so.conf), then "make install" will
1088 automatically run ldconfig.
1090 2. If the library is installed to a non-system directory, the
1091 build system adds a DR_RUNPATH entry to the final binary
1092 pointing to the directory to which the library is installed.
1094 When this support works, the user should be able to run notmuch
1095 immediately after "make install", without any errors trying to find
1096 the notmuch library, and without having to manually set environment
1097 variables such as LD_LIBRARY_PATH.
1099 Check compiler/linker options before using them
1101 The configure script now carefully checks that any desired
1102 compilation options, (whether for enabling compiler warnings, or for
1103 embedding rpath, etc.), are supported. Only supported options are
1104 used in the resulting Makefile.
1106 New test-suite features
1107 -----------------------
1108 New modularization of test suite.
1110 Thanks to a gracious relicensing of the test-suite infrastructure
1111 from the git project, notmuch now has a modular test suite. This
1112 provides the ability to run individual sections of the test suite
1113 rather than the whole things. It also provides better summary of
1114 test results, with support for tests that are expected to fail
1115 (BROKEN and FIXED) in addition to PASS and FAIL. Finally, it makes
1116 it easy to run the test suite within valgrind (pass --valgrind to
1117 notmuch-test or to any sub-script) which has been very useful.
1119 New testing of emacs interface.
1121 The test suite has been augmented to allow automated testing of the
1122 emacs interfaces. So far, this includes basic searches, display of
1123 threads, and tag manipulation. This also includes a test that a new
1124 message can successfully be sent out through a (dummy) SMTP server
1125 and that said message is successfully integrated into the notmuch
1126 database via the FCC setting.
1130 Fix potential corruption of database when "notmuch new " is interrupted.
1132 Previously, an interruption of "notmuch new" would (rarely) result
1133 in a corrupt database. The corruption would manifest itself by a
1134 persistent error of the form:
1136 document ID of 1234 has no thread ID
1138 The message-adding code has been carefully audited and reworked to
1139 avoid this sort of corruption regardless of when it is interrupted.
1141 Fix failure with extremely long message ID headers.
1143 Previously, a message with an extremely long message ID, (say, more
1144 than 300 characters), would fail to be added to notmuch, (triggering
1145 Xapian exceptions). This has now been fixed.
1147 Fix for messages with "charset=unknown-8bit"
1149 Previously, messages with this charset would cause notmuch to emit a
1150 GMime warning, (which would then trip up emacs or other interfaces
1151 parsing the notmuch results).
1153 Fix notmuch_query_search_threads function to return NULL on any exception
1155 Fix "notmuch search" to return non-zero if notmuch_query_search_threads fails
1157 Previously, this command could confusingly report a Xapian
1158 exception, yet still return an error code of 0. It now correctly
1159 returns a failing error code of 1 in this case.
1163 Fix to handle a message with a subject containing, for example "[1234]"
1165 Previously, a message subject containing a sequence of digits within
1166 square brackets would cause the emacs interface to mis-parse the
1167 output of "notmuch search". This would result in the message being
1168 mis-displayed and prevent the user from manipulating the message in
1169 the emacs interface.
1171 Fix to correctly handle message IDs containing ".."
1173 The emacs interface now properly quotes message IDs to avoid a
1174 Xapian bug in which the ".." within a message ID would be
1175 misinterpreted as a numeric range specification.
1177 Python-binding fixes
1178 --------------------
1179 The python bindings for notmuch have been updated to work with python3.
1181 Debian-specific fixes
1182 ---------------------
1183 Fix emacs initialization so "M-x notmuch" works for users by default.
1185 Now, a new Debian user can immediately run "emacs -f notmuch" after
1186 "apt-get install notmuch". Previously, the user would have had to
1187 edit the ~/.emacs file to add "(require 'notmuch)" before this would
1190 Notmuch 0.3.1 (2010-04-27)
1191 ==========================
1194 Fix an infinite loop in "notmuch reply"
1196 This bug could be triggered by replying to a message where the
1197 user's primary email address did not appear in the To: header and
1198 the user had not configured any secondary email addresses. The bug
1199 was a simple re-use of the same iterator variable in nested loops.
1201 Fix a potential SEGV in "notmuch search"
1203 This bug could be triggered by an author name ending in a ','.
1204 Admittedly - that's almost certainly a spam email, but we never
1205 want notmuch to crash.
1209 Fix calculations for line wrapping in the primary "notmuch" view.
1211 Fix Fcc support to prompt to create a directory if the specified Fcc
1212 directory does not exist.
1216 Fix build on OpenSolaris (at least) due to missing 'extern "C"' block.
1218 Without this, the C++ sources could not find strcasestr and the
1219 final linking of notmuch would fail.
1221 Notmuch 0.3 (2010-04-27)
1222 ========================
1223 New command-line features
1224 -------------------------
1225 User-configurable tags for new messages
1227 A new "new.tags" option is available in the configuration file to
1228 determine which tags are applied to new messages. Run "notmuch
1229 setup" to generate new documentation within ~/.notmuch-config on how
1230 to specify this value.
1232 Threads search results named based on subjects that match search
1234 This means that when new mails arrived to a thread you've previously
1235 read, and the new mails have a new subject, you will see that
1236 subject in the search results rather than the old subject.
1238 Faster operation of "notmuch tag" (avoid unneeded sorting)
1240 Since the user just wants to tag all matching messages, we can make
1241 things perform a bit faster by avoiding the sort.
1243 Even Better guessing of From: header for "notmuch reply"
1245 Notmuch now looks at a number of headers when trying to figure out
1246 the best From: header to use in a reply. This is helpful if you have
1247 several configured email addresses, and you also subscribe to various
1248 mailing lists with different addresses, (so that mails you are
1249 replying to won't always include your subscribed address in the To:
1252 Indication of author names that match a search
1254 When notmuch displays threads as the result of a search, it now
1255 lists the authors that match the search before listing the other
1256 authors in the thread. It inserts a pipe '|' symbol between the last
1257 matching and first non-matching author. This is especially useful in
1258 a search that includes tag:unread. Now the authors of the unread
1259 messages in the thread are listed first.
1261 New: Python bindings
1262 --------------------
1263 Sebastian Spaeth has contributed his python bindings for the notmuch
1264 library to the central repository. These bindings were previously
1265 known as "cnotmuch" within python but have now been renamed to be
1266 accessible with a simple, and more official-looking "import notmuch".
1268 The bindings have already proven very useful as people proficient in
1269 python have been able to easily develop programs to do notmuch-based
1270 searches for email-address completion, maildir-flag synchronization,
1273 These bindings are available within the bindings/python directory, but
1274 are not yet integrated into the top-level Makefiles, nor the top-level
1275 package-building scripts. Improvements are welcome.
1277 Emacs interface improvements
1278 ----------------------------
1279 An entirely new initial view for notmuch, (friendly yet powerful)
1281 Some of us call the new view "notmuch hello" but you can get at it
1282 by simply calling "emacs -f notmuch". The new view provides a search
1283 bar where new searches can be performed. It also displays a list of
1284 recent searches, along with a button to save any of these, giving it
1285 a new name as a "saved search". Many people find these "saved
1286 searches" one of the most convenient ways of organizing their mail,
1287 (providing all of the features of "folders" in other mail clients,
1288 but without any of the disadvantages).
1290 Finally, this view can also optionally display all of the tags that
1291 exist in the database, along with a count for each tag, and a custom
1292 search of messages with that tag that's simply a click (or keypress)
1295 Note: For users that liked the original mode of "emacs -f notmuch"
1296 immediately displaying a particular search result, we
1297 recommend instead running something like:
1299 emacs --eval '(notmuch search "tag:inbox" t)'
1301 The "t" means to sort the messages in an "oldest first" order,
1302 (as notmuch would do previously by default). You can also
1303 leave that off to have your search results in "newest first"
1306 Full-featured "customize" support for configuring notmuch
1308 Notmuch now plugs in well to the emacs "customize" mode to make it
1309 much simpler to find things about the notmuch interface that can be
1310 tweaked by the user.
1312 You can get to this mode by starting at the main "Customize" menu in
1313 emacs, then browsing through "Applications", "Mail", and
1314 "Notmuch". Or you can go straight to "M-x customize-group"
1317 Once you're at the customize screen, you'll see a list of documented
1318 options that can be manipulated along with checkboxes, drop-down
1319 selectors, and text-entry boxes for configuring the various
1322 Support for doing tab-completion of email addresses
1324 This support currently relies on an external program,
1325 (notmuch-addresses), that is not yet shipped with notmuch
1326 itself. But multiple, suitable implementations of this program have
1327 already been written that generate address completions by doing
1328 notmuch searches of your email collection. For example, providing
1329 first those addresses that you have composed messages to in the
1332 One such program (implemented in python with the python bindings to
1333 notmuch) is available via:
1335 git clone http://jkr.acm.jhu.edu/git/notmuch_addresses.git
1337 Install that program as notmuch-addresses on your PATH, and then
1338 hitting TAB on a partial email address or name within the To: or Cc:
1339 line of an email message will provide matching completions.
1341 Support for file-based (Fcc) delivery of sent messages to mail store
1343 This isn't yet enabled by default. To enable this, one will have to
1344 set the "Notmuch Fcc Dirs" setting within the notmuch customize
1345 screen, (see its documentation there for details). We anticipate
1346 making this automatic in a future release.
1348 New 'G' key binding to trigger mail refresh (G == "Get new mail")
1350 The 'G' key works wherever '=' works. Before refreshing the screen
1351 it calls an external program that can be used to poll email servers,
1352 run notmuch new and setup specific tags for the new emails. The
1353 script to be called should be configured with the "Notmuch Poll
1354 Script" setting in the customize interface. This script will
1355 typically invoke "notmuch new" and then perhaps several "notmuch
1358 Implement emacs message display with the JSON output from notmuch.
1360 This is much more robust than the previous implementation, (where
1361 some HTML mails and mail quoting the notmuch code with the delimiter
1362 characters in it would cause the parser to fall over).
1364 Better handling of HTML messages and MIME attachments (inline images!)
1366 Allow for any MIME parts that emacs can display to be displayed
1367 inline. This includes inline viewing of image attachments, (provided
1368 the window is large enough to fit the image at its natural size).
1370 Much more robust handling of HTML messages. Currently both text/plain
1371 and text/html alternates will be rendered next to each other. In a
1372 future release, users will be able to decide to see only one or the
1373 other representation.
1375 Each attachment now has its own button so that attachments can be
1376 saved individually (the 'w' key is still available to save all
1379 Customizable support for tidying of text/plain message content
1381 Many new functions are available for tidying up message
1382 content. These include options such as wrapping long lines,
1383 compressing duplicate blank lines, etc.
1385 Most of these are disabled by default, but can easily be enabled by
1386 clicking the available check boxes under the "Notmuch Show Insert
1387 Text/Plain Hook" within the notmuch customize screen.
1389 New support for searchable citations (even when hidden)
1391 When portions of overly-long citations are hidden, the contents of
1392 these citations will still be available for emacs' standard
1393 "incremental search" functions. When the search matches any portion
1394 of a hidden citation, the citation will become visible temporarily
1395 to display the search result.
1397 More flexible handling of header visibility
1399 As an answer to complaints from many users, the To, Cc, and Date
1400 headers of messages are no longer hidden by default. For those users
1401 that liked that these were hidden, a new "Notmuch Messages Headers
1402 Visible" option in the customize interface can be set to nil. The
1403 visibility of headers can still be toggled on a per-message basis
1404 with the 'h' keybinding.
1406 For users that don't want to see some subset of those headers, the
1407 new "Notmuch Message Headers" variable can be customized to list
1408 only those headers that should be present in the display of a message.
1410 The Return key now toggles message visibility anywhere
1412 Previously this worked only on the first summary-line of a message.
1414 Customizable formatting of search results
1416 The user can easily customize the order, width, and formatting of
1417 the various fields in a "notmuch search" buffer. See the "Notmuch
1418 Search Result Format" section of the customize interface.
1420 Generate nicer names for search buffers when using a saved search.
1422 Add a notmuch User-Agent header when sending mail from notmuch/emacs.
1424 New keybinding (M-Ret) to open all collapsed messages in a thread.
1428 Provide a new NOTMUCH_SORT_UNSORTED value for queries
1430 This can be somewhat faster when sorting simply isn't desired. For
1431 example when collecting a set of messages that will all be
1432 manipulated identically, (adding a tag, removing a tag, deleting the
1433 messages), then there's no advantage to sorting the messages by
1438 Fix to compile against GMime 2.6
1440 Previously notmuch insisted on being able to find GMime 2.4, (even
1441 though GMime 2.6 would have worked all along).
1443 Fix configure script to accept (and ignore) various standard options.
1445 For example, those that the Gentoo build scripts expect configure to
1446 accept are now all accepted.
1450 A large number of new tests for the many new features.
1452 Better display of output from failed tests.
1454 Now shows failures with diff rather than forcing the user to gaze at
1455 complete actual and expected output looking for deviation.
1457 Notmuch 0.2 (2010-04-16)
1458 ========================
1459 This is the second release of the notmuch mail system, with actual
1460 detailed release notes this time!
1462 This release consists of a number of minor new features that make
1463 notmuch more pleasant to use, and a few fairly major bug fixes.
1465 We didn't quite hit our release target of "about a week" from the 0.1
1466 release, (0.2 is happening 11 days after 0.1), but we hope to do
1467 better for next week. Look forward to some major features coming to
1468 notmuch in subsequent releases.
1474 Better guessing of From: header.
1476 Notmuch now tries harder to guess which configured address should be
1477 used as the From: line in a "notmuch reply". It will examine the
1478 Received: headers if it fails to find any configured address in To:
1479 or Cc:. This allows it to often choose the correct address even when
1480 replying to a message sent to a mailing list, and not directly to a
1483 Make "notmuch count" with no arguments count all messages
1485 Previously, it was hard to construct a search term that was
1486 guaranteed to match all messages.
1488 Provide a new special-case search term of "*" to match all messages.
1490 This can be used in any command accepting a search term, such as
1491 "notmuch search '*'". Note that you'll want to take care that the
1492 shell doesn't expand * against the current files. And note that the
1493 support for "*" is a special case. It's only meaningful as a single
1494 search term and loses its special meaning when combined with any
1497 Automatically detect thread connections even when a parent message is
1500 Previously, if two or more message were received with a common
1501 parent, but that parent was not received, then these messages would
1502 not be recognized as belonging to the same thread. This is now fixed
1503 so that such messages are properly connected in a thread.
1507 Fix potential data loss in "notmuch new" with SIGINT
1509 One code path in "notmuch new" was not properly handling
1510 SIGINT. Previously, this could lead to messages being removed from
1511 the database (and their tags being lost) if the user pressed
1512 Control-C while "notmuch new" was working.
1514 Fix segfault when a message includes a MIME part that is empty.
1516 Fix handling of non-ASCII characters with --format=json
1518 Previously, characters outside the range of 7-bit ASCII were
1519 silently dropped from the JSON output. This led to corrupted display
1520 of utf-8 content in the upcoming notmuch web-based frontends.
1522 Fix headers to be properly decoded in "notmuch reply"
1524 Previously, the user might see:
1526 Subject: Re: =?iso-8859-2?q?Rozlu=E8ka?=
1530 Subject: Re: Rozlučka
1532 The former text is properly encoded to be RFC-compliant SMTP, will
1533 be sent correctly, and will be properly decoded by the
1534 recipient. But the user trying to edit the reply would likely be
1535 unable to read or edit that field in its encoded form.
1537 Emacs client features
1538 ---------------------
1539 Show the last few lines of citations as well as the first few lines.
1541 It's often the case that the last sentence of a citation is what is
1542 being replied to directly, so the last few lines are often much more
1543 important. The number of lines shown at the beginning and end of any
1544 citation can be configured, (notmuch-show-citation-lines-prefix and
1545 notmuch-show-citation-lines-suffix).
1547 The '+' and '-' commands in the search view can now add and remove
1550 Selective bulk tagging is now possible by selecting a region of
1551 threads and then using either the '+' or '-' keybindings. Bulk
1552 tagging is still available for all threads matching the current
1553 search with the '*' binding.
1555 More meaningful buffer names for thread-view buffers.
1557 Notmuch now uses the Subject of the thread as the buffer
1558 name. Previously it was using the thread ID, which is a meaningless
1561 Provide for customized colors of threads in search view based on tags.
1563 See the documentation of notmuch-search-line-faces, (or us "M-x
1564 customize" and browse to the "notmuch" group within "Applications"
1565 and "Mail"), for details on how to configure this colorization.
1567 Build-system features
1568 ---------------------
1569 Add support to properly build libnotmuch on Darwin systems (OS X).
1571 Add support to configure for many standard options.
1573 We include actual support for:
1575 --includedir --mandir --sysconfdir
1577 And accept and silently ignore several more:
1579 --build --infodir --libexecdir --localstatedir
1580 --disable-maintainer-mode --disable-dependency-tracking
1582 Install emacs client in "make install" rather than requiring a
1583 separate "make install-emacs".
1585 Automatically compute versions numbers between releases.
1587 This support uses the git-describe notation, so a version such as
1588 0.1-144-g43cbbfc indicates a version that is 144 commits since the
1589 0.1 release and is available as git commit "43cbbfc".
1591 Add a new "make test" target to run the test suite and actually verify
1594 Notmuch 0.1 (2010-04-05)
1595 ========================
1596 This is the first release of the notmuch mail system.
1598 It includes the libnotmuch library, the notmuch command-line
1599 interface, and an emacs-based interface to notmuch.
1601 Note: Notmuch will work best with Xapian 1.0.18 (or later) or Xapian
1602 1.1.4 (or later). Previous versions of Xapian (whether 1.0 or 1.1) had
1603 a performance bug that made notmuch very slow when modifying
1604 tags. This would cause distracting pauses when reading mail while
1605 notmuch would wait for Xapian when removing the "inbox" and "unread"
1606 tags from messages in a thread.
