+Notmuch 0.6 (2011-07-XX)
+=======================
+New, general features
+---------------------
+Folder-based searching
+
+ Notmuch queries can now include a search term to match the
+ directories in which mail files are stored (within the mail
+ storage). The syntax is as follows:
+
+ folder:<path>
+
+ For example, one might use things such as:
+
+ folder:spam
+ folder:2011/06
+
+ or anything else that matches directories within your mail storage.
+
+ This feature is particularly useful for users of delivery-agent
+ software (such as procmail or maildrop) that is filtering mail and
+ delivering it to particular folders, or users of systems such as
+ Gmail that use filesystem directories to indicate message tags.
+
+ NOTE: Only messages that are newly indexed with this version of
+ notmuch will be searchable with folder: terms. In order to enable
+ this feature for all mail, the entire notmuch index will need to be
+ rebuilt as follows:
+
+ notmuch dump > notmuch.dump
+ # Backup, then remove notmuch database ($MAIL/.notmuch)
+ notmuch new
+ notmuch restore notmuch.dump
+
+New, automatic tags: "signed" and "encrypted"
+
+ These tags will automatically be applied to messages containing
+ multipart/signed and multipart/encrypted parts.
+
+ NOTE: Only messages that are newly indexed with this version of
+ notmuch will receive these tags. In order to enable this feature for
+ all mail, the entire notmuch index will need to be rebuilt (see
+ above).
+
+New command-line features
+-------------------------
+Add new "notmuch show --verify" option for signature verification
+
+ This option instruct notmuch to verify the signature of
+ PGP/MIME-signed parts.
+
+Add new "notmuch show --decrypt" and "notmuch reply --decrypt" options
+
+ This option instructs notmuch to decrypt PGP/MIME-encrypted parts.
+
+Proper nesting of multipart parts in "notmuch show" output
+
+ MIME parts are now display with proper nesting to reflect original
+ MIME hierarchy of a message. This allows clients to correctly
+ analyze the MIME structure, (such as, for example, determining to
+ which parts a signature part applies).
+
+Add new "notmuch show --part" option
+
+ This is a replacement for the older "notmuch part" command, (which
+ is now deprecated—it should still work as always, but is no longer
+ documented). Putting part output under "notmuch show" allows for all
+ of the "notmuch show" options to be applied when extracting a single
+ part, (such as --format=json for extracting a message part with JSON
+ formatting).
+
+Deprecate "notmuch search-tags", (in favor of "notmuch search --output=tags *")
+
+ The "notmuch search-tags" sub-command has been redundant since the
+ addition of the --output=tags option to "notmuch search". We now
+ make that more clear by deprecating "notmuch search-tags", (dropping
+ it from the documentation). We do continue to support the old syntax
+ by translating it internally to the new call.
+
+Performance improvements
+------------------------
+Faster searches (by doing fewer serches to construct threads)
+
+ Whenever a user asks for search results as threads, notmuch first
+ performs a search for messages matching the query, then performs
+ additional searches to find other messages in the resulting threads.
+
+ Removing inefficiences and redundancies in these secondary searches
+ results in a measured speedups of 1.5x for a typical search.
+
+Faster searches (by doing fewer passes to gather message data)
+
+ Optimizing Xapian data access patterns (using a single pass to get
+ all message-document data rather than a ps for each data type)
+ results in a measured speedup of 1.7x for a typical search.
+
+ The benefits of this optimization combine with the preceding
+ optimization. With both in place, Austin Clements measured a speedup
+ of 2.5x for a search of all messages in his inbox (was 4.5s, now
+ 1.8s). Thanks, Austin!
+
+Faster initial indexing
+
+ More efficient indexing of new messages results in a measured
+ speedup of 1.4x for the initial indexing of 3 GB of mail (1h 14m
+ rather than 1h 46m). Thanks to Austin Clements and Michal Sojka.
+
+Make "notmuch new" faster for unchanged directories
+
+ Optimizing to not do any further examinations of sub-directories
+ when the filesystem indicates that a directory is unchanged from the
+ last "notmuch new" results in measured speedups of 8.5 for the "No
+ new mail" case, (was 0.77s, now 0.09s). Thanks to Austin Clements
+ and Karel Zak.
+
+New emacs-interface features
+----------------------------
+Output of pipe command is now displayed if pipe command fails
+
+ This is extremely useful in the common use case of piping a patch to
+ "git am". If git fails to cleanly merge the patch the error messages
+ from the failed merge are now clearly displayed to the user, (where
+ previously they were silently hidden from the user).
+
+User-selectable From address
+
+ A user can choose which configured email addresses should be used as
+ the From address whenever composing a new message. To do so, simply
+ press C-u before the command which will open a new message. Emacs
+ will prompt for the from address to use.
+
+ The user can customize the "Notmuch Identities" setting in the
+ notmuch cutomize group in order to use addresses other than those in
+ the notmuch configuration file if desired.
+
+ The user can also choose to always be prompted for the from address
+ when composing a new message (without having to use C-u) by setting
+ the "Notmuch Always Prompt For Sender" option in the notmuch
+ customize group.
+
+Automatic detection and hiding of original message in top-posted message
+
+ When a message contains a line looking something like:
+
+ ----- Original Message -----
+
+ emacs hides this and all subsequent lines as an "original message",
+ (allowing the user to click or press enter on the "original message"
+ button to display it again). This makes the handling of top-posted
+ citations work much like conventional citations.
+
+New hooks for running code when tags are modified
+
+ Some users want to perform additional actions whenever a particular
+ tag is added/removed from a message. This could be used to, for
+ example, interface with some external spam-recognition training
+ tool. T facilitate this, two new hooks are added which can be
+ modified in the following settings of the notmuch customize group:
+
+ Notmuch Before Tag Hook
+ Notmuch After Tag Hook
+
+New optional support for hiding some multipart/alternative parts
+
+ Many emails are sent with redundant content within a
+ multipart/alternative group (such as a text/plain part as well as a
+ text/html part). Users can configure the setting:
+
+ Notmuch Show All Multipart/Alternative Parts
+
+ to "off" in the notmuch customize group to have the interface
+ automatically hide some part alternatives (such as text/html
+ parts). This new part hiding is not configured by default yet
+ because there's not yet a simple way to re-display such a hidden
+ part if it is not actually redundant with a displayed part.
+
+Better rendering of text/x-vcalendar parts
+
+ These parts are now displayed in a format suitable for use with the
+ emacs diary.
+
+Avoid getting confused by Subject and Author fields with newline characters
+
+ Replacing all characters with ACII code less than 32 with a question mark.
+
+Cleaner display of From line in email messages (remove double quotes,
+and drop "name" if it's actually just a repeat of the email address).
+
+Vim interface improvements
+--------------------------
+Felipe Contreras provided a number of updates for the vim interface.
+
+ Using sendmail directly rather than mailx,
+
+ Implementing archive in show view
+
+ Add support to mark as read in show and search views
+
+ Add delete commands
+
+ Various cleanups.
+
+Bindings improvements
+---------------------
+Ruby bindings are now much more complete
+
+ Including QUERY.sort, QUERY.to_s, MESSAGE.maildir_flags_to_tags,
+ MESSAGE.tags_to_maildir_flags, and MESSAGE.get_filenames
+
+Python bindings are now much more complete
+
+ Including Message().get_filenames(),
+ Message().tags_to_maildir_flags(), Threads().__nonzero__,
+ Tags().__nonzero__()
+
+ Also implement Message.__cmp__ and __hash__
+ These allow, for example:
+
+ if msg1 == msg2
+
+ As well as set arithmetic on Messages():
+
+ s1, s2= msgs1, msgs2
+ s1.union(s2)
+ s2 -= s1
+
+Added initial Go bindings in bindings/go
+
+New build-system features
+-------------------------
+Added support for building in a directory other than the source directory
+
+ This can be used with the widely-supported idiom of simply running
+ the configure script from some other directory:
+
+ mkdir build
+ cd build
+ ../configure
+ make
+
+Fix to save configure options for future, implicit runs of configure
+
+ When a user updates the source (such as with "git pull") calling
+ "make" may cause an automatic re-run of the configure script. When
+ this happens, the configure script will automatically be called with
+ the same options the user originally passed in the most-recent
+ manual invocation of configure.
+
+New test-suite feature
+----------------------
+Binary for bash for running test suite now located via PATH.
+
+ The notmuch test suite requires a fairly recent version of bash (>=
+ bash 4). As some systems supply an older version of bash at
+ /bin/bash, the test suite is now updated to search $PATH to locate
+ the bash binary. This allows users of systems with old /bin/bash to
+ simply install bash >= 4 somwhere on $PATH before /bin and then use
+ the test suite.
+
+Support for testing output with a trailing newline.
+
+ Previously, some tests would fail to notice a difference in the
+ presense/absence of a trailing newline in a program output, (which
+ has led to bugs in the past). Now, carefully-written tests (using
+ test_expect_equal_file rather than test_expect_equal) will detect
+ any change in the presence/absence of a trailing newline. Many tests
+ are updated to take advnatage of this.
+
+Avoiding accessing user's $HOME while running test suite
+
+ The test suite now carefully creates its own HOME directory. This
+ allows the test suite to be run with no existing HOME directory, (as
+ some build systems apparently do), and avoids test-suite differences
+ due to configuration files in the users HOME directory.
+
+
+General bug fixes
+-----------------
+Output *all* files for "notmuch search --output=files"
+
+ For the cases where multiple files have the same Message ID,
+ previous versions of notmuch would output only one such file. This
+ command is now fixed to correctly output all files.
+
+Fixed spurious search results from "overlapped" indexing of addresses
+
+ This fixed a bug where a search for:
+
+ to:user@elsewhere.com
+
+ would incorrectly match a message sent:
+
+ To: user@example,com, someone@elsewhere.com
+
+Fix --output=json when search has no results
+
+ A bug present since notmuch 0.4 had caused searches with no results
+ to produce an invalid json object. This is now fixed to cleanly
+ return a valid json object representing an empty array "[]" as
+ expected.
+
+fix the automatic detection of the From address for "notmuch reply"
+from the Received headers in some cases.
+
+Fix core dump on DragonFlyBSD due to -1 return value from
+sysconf(_SC_GETPW_R_SIZE_MAX).
+
+Cleaned up several memory leaks
+
+Eliminated a few, rare segmentation faults and a double-free.
+
+Fix libnotmuch library to only export notmuch API functions
+
+ Previous release of the notmuch library also exported some Xapian
+ C++ exception type symbols. These were never part of the library
+ interface and were never intented to be exported.
+
+Emacs-interface bug fixes
+-------------------------
+Display any unexpected output or errors from "notmuch search" invocations
+
+ Previously any misformatted output or trailing error messages were
+ silently ignored. This output is now clearly displayed. This fix was
+ very helpful in identifying and fixing the bug decribed below.
+
+Fix bug where some threads would be missing from large search results
+
+ When a search returned a "large" number of results, the emacs
+ interface was incorrectly dropping one thread everytime the output
+ of the "notmuch search" process spanned the emacss read-buffer. This
+ is now fixed.
+
+Avoid rec-compression of .gz files (and similar) when saving attachment
+
+ Emacs was being too clever for its own good and trying to
+ re-compress pre-compressed .gz files when saving such attachments
+ (potentially corrupting the attachment). The emacs interface is
+ fixed to avoid this bug.
+
+Fix hiding of a message when a previously-hidden citation is visible
+
+ Previously the citation would remain visible in this case. This is
+ fixed so that hiding a message hides all parts.
+
+Notmuch 0.5 (2010-11-11)
+========================
+New, general features
+---------------------
+Maildir-flag synchronization
+
+ Notmuch now knows how to synchronize flags in maildir filenames with
+ tags in the notmuch database. The following flag/tag mappings are
+ supported:
+
+ Flag <-> Tag
+ ---- -----
+ 'D' draft
+ 'F' flagged
+ 'P' passed
+ 'R' replied
+ 'S' unread (added when 'S' flag is not present)
+
+ The synchronization occurs in both directions, (for example, adding
+ the 'S' flag to a file will cause the "unread" tag to be added, and
+ adding the "replied" tag to a message will cause the file to be
+ renamed with an 'R' flag).
+
+ This synchronization is enabled by default for users of the
+ command-line interface, (though only files in directories named
+ "cur" or "new" will be renamed). It can be disabled by setting the
+ new maildir.synchronize_flags option in the configuration file. For
+ example:
+
+ notmuch config set maildir.synchronize_flags false
+
+ Users upgrading may also want to run "notmuch setup" once (just
+ accept the existing configuration) to get a new, nicely-commented
+ [maildir] section added to the configuration file.
+
+ For users of the notmuch library, the new synchronization
+ functionality is available with the following two new functions:
+
+ notmuch_message_maildir_flags_to_tags
+ notmuch_message_tags_to_maildir_flags
+
+ It is anticipated that future improvements to this support will
+ allow for safe synchronization of the 'T' flag with the "deleted"
+ tag, as well as support for custom flag/tag mappings.
+
+New library features
+--------------------
+Support for querying multiple filenames for a single message
+
+ It is common for the mailstore to contain multiple files with the
+ same message ID. Previously, notmuch would always hide these
+ duplicate files, (returning a single, arbitrary filename with
+ notmuch_message_get_filename).
+
+ With this release, library users can access all filenames for a
+ message with the new function:
+
+ notmuch_message_get_filenames
+
+ Together with notmuch_filenames_valid, notmuch_filenames_get, and
+ notmuch_filenames_move_to_next it is now possible to iterate over
+ all available filenames for a given message.
+
New command-line features
-------------------------
New "notmuch show --format=raw" for getting at original email contents
the --format=json output, (which would previously produce "[]" and
now produces nothing).
+Emacs interface improvements
+----------------------------
+Fix to allow pipe ('|') command to work when using notmuch over ssh
+
+Fix count of lines in hidden signatures.
+
+Omit repeated subject lines in (collapsed) thread display.
+
+Display current thread subject in a header line.
+
+Provide a "c i" binding to copy a thread ID from the search view.
+
+Allow for notmuch-fcc-dirs to have a value of nil.
+
+ Also, the more complex form of notmuch-fcc-dirs now has a slightly
+ different format. It no longer has a special first-element, fallback
+ string. Instead it's now a list of cons cells where the car of each
+ cell is a regular expression to be matched against the sender
+ address, and the cdr is the name of a folder to use for an FCC. So
+ the old fallback behavior can be achieved by including a fineal cell
+ of (".*" . "default-fcc-folder").
+
+Vim interface improvements
+--------------------------
+Felipe Contreras provided a number of updates for the vim interface.
+
+ These include optimiations, support for newer versions of vim, fixed
+ support for sending mail on modern systmms, new commands, and
+ various cleanups.
+
+New bindings
+------------
+Added initial ruby bindings in bindings/ruby
