+New command-line features
+-------------------------
+New "notmuch show --format=raw" for getting at original email contents
+
+ This new feature allows for a fully-functional email client to be
+ built on top of the notmuch command-line without needing any direct
+ access to the mail store itself.
+
+ For example, it's now possible to run "emacs -f notmuch" on a local
+ machine with only ssh access to the mail store/notmuch database. To
+ do this, simply set the notmuch-command variable in emacs to the
+ name of a script containing:
+
+ ssh user@host notmuch "$@"
+
+ If the ssh client has enabled connection sharing (ControlMaster
+ option in OpenSSH), the emacs interface can be quite responsive this
+ way.
+
+General bug fixes
+-----------------
+Fix "notmuch search" to print nothing when nothing matches
+
+ The 0.4 release had a bug in which:
+
+ notmuch search <expression-with-no-matches>
+
+ would produce a single blank line of output, (where previous
+ versions would produce no output. This fix also causes a change in
+ the --format=json output, (which would previously produce "[]" and
+ now produces nothing).
+
+Notmuch 0.4 (2010-11-01)
+========================
+New command-line features
+-------------------------
+notmuch search --output=(summary|threads|messages|tags|files)
+
+ This new option allows for particular items to be returned from
+ notmuch searches. The "summary" option is the default and behaves
+ just as "notmuch search" has historically behaved.
+
+ The new option values allow for thread IDs, message IDs, lists of
+ tags, and lists of filenames to be returned from searches. It is
+ expected that this new option will be very useful in shell
+ scripts. For example:
+
+ for file in $(notmuch search --output=files <search-terms>); do
+ <operations-on> "$file"
+ done
+
+notmuch show --format=mbox <search-specification>
+
+ This new option allows for the messages matching a search
+ specification to be presented as an mbox. Specifically the "mboxrd"
+ format is used which allows for reversible quoting of lines
+ beginning with "From ". A reader should remove a single '>' from the
+ beginning of all lines beginning with one or more '>' characters
+ followed by the 5 characters "From ".
+
+notmuch config [get|set] <section>.<item> [value ...]
+
+ The new top-level "config" command allows for any value in the
+ notmuch configuration file to be queried or set to a new value. Both
+ single-valued and multi-valued items are supported, as our any
+ custom items stored in the configuration file.
+
+Avoid setting Bcc header in "notmuch reply"
+
+ We decided that this was a bit heavy-handed as the actual mail
+ user-agent should be responsible for setting any Bcc option. Also,
+ see below for the notmuch/emacs user-agent now setting an Fcc by
+ default rather than Bcc.
+
+New library features
+--------------------
+Add notmuch_query_get_query_string and notmuch_query_get_sort
+
+ These are simply functions for querying properties of a
+ notmuch_query_t object.
+
+New emacs features
+------------------
+Enable Fcc of all sent messages by default (to "sent" directory)
+
+ All messages sent from the emacs interface will now be saved to the
+ notmuch mail store where they will be incorporated to the database
+ by the next "notmuch new". By default, messages are saved to the
+ "sent" directory at the top-level of the mail store. This directory
+ can be customized by means of the "Notmuch Fcc Dirs" option in the
+ notmuch customize interface.
+
+Ability to all open messages in a thread to a pipe
+
+ Historically, the '|' keybinding allows for piping a single message
+ to an external command. Now, by prefixing this key with a prefix
+ argument, (for example, by pressing "Control-U |"), all open
+ messages in the current thread will be sent to the external command.
+
+Optional support for detecting inline patches
+
+ This hook is disabled by default but can be enabled with a checkbox
+ under "Notmuch Show Insert Text/Plain Hook" in the notmuch customize
+ interface. It allows for inline patches to be detected and treated
+ as if they were attachments, (with context-sensitive highlighting).
+
+Automatically tag messages as "replied" when sending a reply
+
+ Messages replied to within the emacs interface will now be tagged as
+ "replied". This feature can easily be customized to add or remove
+ other tags as well. For example, a user might use a tag of
+ "needs-reply" and can configure this feature to automatically remove
+ that tag when replying. See "Notmuch Message Mark Replied" in the
+ notmuch customize interface.
+
+Allow search-result color specifications to overlay each other
+
+ For example, one tag can specify the background color of matching
+ lines, while another can specify the foreground. With this change,
+ both settings will now be visible simultaneously, (which was not the
+ case in previous releases). See "Notmuch Search Line Faces" in the
+ notmuch customize interface.
+
+Make hidden author names still available for incremental search.
+
+ When there is insufficient space to display all authors of a thread
+ in search results, the names of hidden authors are now still made
+ available to emacs' incremental search commands. As the user
+ searches, matching lines will temporarily expand to show the hidden
+ names.
+
+New binding of Control-TAB (works like TAB in reverse)
+
+ Many notmuch nodes already use TAB to navigate forward through
+ various items allowing actions, (message headers, email attachments,
+ etc.). The new Control-TAB binding operates similarly but in the
+ opposite direction.
+
+New build-system features
+-------------------------
+Various portability fixes have been applied
+
+ These include fixes for build failures on at least Solaris, FreeBSD,
+ and Fedora systems. We're hopeful that the notmuch code base is now
+ more portable than ever before.
+
+Arrange for libnotmuch to be found automatically after make install
+
+ The notmuch build system is now careful to help the user avoid
+ errors of the form "libnotmuch.so could not be found" immediately
+ after installing. This support takes two forms:
+
+ 1. If the library is installed to a system directory,
+ (configured in /etc/ld.so.conf), then "make install" will
+ automatically run ldconfig.
+
+ 2. If the library is installed to a non-system directory, the
+ build system adds a DR_RUNPATH entry to the final binary
+ pointing to the directory to which the library is installed.
+
+ When this support works, the user should be able to run notmuch
+ immediately after "make install", without any errors trying to find
+ the notmuch library, and without having to manually set environment
+ variables such as LD_LIBRARY_PATH.
+
+Check compiler/linker options before using them
+
+ The configure script now carefully checks that any desired
+ compilation options, (whether for enabling compiler warnings, or for
+ embedding rpath, etc.), are supported. Only supported options are
+ used in the resulting Makefile.
+
+New test-suite features
+-----------------------
+New modularization of test suite.
+
+ Thanks to a gracious relicensing of the test-suite infrastructure
+ from the git project, notmuch now has a modular test suite. This
+ provides the ability to run individual sections of the test suite
+ rather than the whole things. It also provides better summary of
+ test results, with support for tests that are expected to fail
+ (BROKEN and FIXED) in addition to PASS and FAIL. Finally, it makes
+ it easy to run the test suite within valgrind (pass --valgrind to
+ notmuch-test or to any sub-script) which has been very useful.
+
+New testing of emacs interface.
+
+ The test suite has been augmented to allow automated testing of the
+ emacs interfaces. So far, this includes basic searches, display of
+ threads, and tag manipulation. This also includes a test that a new
+ message can successfully be sent out through a (dummy) SMTP server
+ and that said message is successfully integrated into the notmuch
+ database via the FCC setting.
+
+General bug fixes
+-----------------
+Fix potential corruption of database when "notmuch new " is interrupted.
+
+ Previously, an interruption of "notmuch new" would (rarely) result
+ in a corrupt database. The corruption would manifest itself by a
+ persistent error of the form:
+
+ document ID of 1234 has no thread ID
+
+ The message-adding code has been carefully audited and reworked to
+ avoid this sort of corruption regardless of when it is interrupted.
+
+Fix failure with extremely long message ID headers.
+
+ Previously, a message with an extremely long message ID, (say, more
+ than 300 characters), would fail to be added to notmuch, (triggering
+ Xapian exceptions). This has now been fixed.
+
+Fix for messages with "charset=unknown-8bit"
+
+ Previously, messages with this charset would cause notmuch to emit a
+ GMime warning, (which would then trip up emacs or other interfaces
+ parsing the notmuch results).
+
+Fix notmuch_query_search_threads function to return NULL on any exception
+
+Fix "notmuch search" to return non-zero if notmuch_query_search_threads fails
+
+ Previously, this command could confusingly report a Xapian
+ exception, yet still return an error code of 0. It now correctly
+ returns a failing error code of 1 in this case.
+
+Emacs bug fixes
+---------------
+Fix to handle a message with a subject containing, for example "[1234]"
+
+ Previously, a message subject containing a sequence of digits within
+ square brackets would cause the emacs interface to mis-parse the
+ output of "notmuch search". This would result in the message being
+ mis-displayed and prevent the user from manipulating the message in
+ the emacs interface.
+
+Fix to correctly handle message IDs containing ".."
+
+ The emacs interface now properly quotes message IDs to avoid a
+ Xapian bug in which the ".." within a message ID would be
+ misinterpreted as a numeric range specification.
+
+Python-binding fixes
+--------------------
+The python bindings for notmuch have been updated to work with python3.
+
+Debian-specific fixes
+---------------------
+Fix emacs initialization so "M-x notmuch" works for users by default.
+
+ Now, a new Debian user can immediately run "emacs -f notmuch" after
+ "apt-get install notmuch". Previously, the user would have had to
+ edit the ~/.emacs file to add "(require 'notmuch)" before this would
+ work.
+
+Notmuch 0.3.1 (2010-04-27)
+==========================
+General bug fixes
+-----------------
+Fix an infinite loop in "notmuch reply"
+
+ This bug could be triggered by replying to a message where the
+ user's primary email address did not appear in the To: header and
+ the user had not configured any secondary email addresses. The bug
+ was a simple re-use of the same iterator variable in nested loops.
+
+Fix a potential SEGV in "notmuch search"
+
+ This bug could be triggered by an author name ending in a ','.
+ Admittedly - that's almost certainly a spam email, but we never
+ want notmuch to crash.
+
+Emacs bug fixes
+---------------
+Fix calculations for line wrapping in the primary "notmuch" view.
+
+Fix Fcc support to prompt to create a directory if the specified Fcc
+directory does not exist.
+
+Build fix
+---------
+Fix build on OpenSolaris (at least) due to missing 'extern "C"' block.
+
+ Without this, the C++ sources could not find strcasestr and the
+ final linking of notmuch would fail.
+
Notmuch 0.3 (2010-04-27)
========================
New command-line features
inline. This includes inline viewing of image attachments, (provided
the window is large enough to fit the image at its natural size).
- Much more robust handling of HTML messages. Currently both text/plan
+ Much more robust handling of HTML messages. Currently both text/plain
and text/html alternates will be rendered next to each other. In a
future release, users will be able to decide to see only one or the
other representation.
