Notmuch 0.2 (2010-04-16)
========================

This is the second release of the notmuch mail system, with actual
detailed release notes this time!

This release consists of a number of minor new features that make
notmuch more pleasant to use, and a few fairly major bug fixes.

We didn't quite hit our release target of "about a week" from the 0.1
release, (0.2 is happening 11 days after 0.1), but we hope to do
better for next week. Look forward to some major features coming to
notmuch in subsequent releases.

General features
----------------

* **_Better guessing of From: header_**

  Notmuch now tries harder to guess which configured address should be
  used as the From: line in a "notmuch reply". It will examine the
  Received: headers if it fails to find any configured address in To:
  or Cc:. This allows it to often choose the correct address even when
  replying to a message sent to a mailing list, and not directly to a
  configured address.

* **_Make "notmuch count" with no arguments count all messages_**

  Previously, it was hard to construct a search term that was
  guaranteed to match all messages.

* **_Provide a new special-case search term of "*" to match all messages_**

  This can be used in any command accepting a search term, such as
  "notmuch search '*'". Note that you'll want to take care that the
  shell doesn't expand * against the current files. And note that the
  support for "*" is a special case. It's only meaningful as a single
  search term and loses its special meaning when combined with any
  other search terms.

* **_Automatically detect thread connections even when a parent message
  is missing_**

  Previously, if two or more message were received with a common
  parent, but that parent was not received, then these messages would
  not be recognized as belonging to the same thread. This is now fixed
  so that such messages are properly connected in a thread.

General bug fixes
-----------------

* **_Fix potential data loss in "notmuch new" with SIGINT_**

  One code path in "notmuch new" was not properly handling
  SIGINT. Previously, this could lead to messages being removed from
  the database (and their tags being lost) if the user pressed
  Control-C while "notmuch new" was working.

* **_Fix segfault when a message includes a MIME part that is empty_**

* **_Fix handling of non-ASCII characters with --format=json_**

  Previously, characters outside the range of 7-bit ASCII were
  silently dropped from the JSON output. This led to corrupted display
  of utf-8 content in the upcoming notmuch web-based frontends.

* **_Fix headers to be properly decoded in "notmuch reply"_**

  Previously, the user might see:

	    Subject: Re: =?iso-8859-2?q?Rozlu=E8ka?=

  rather than:

	    Subject: Re: Rozlučka

  The former text is properly encoded to be RFC-compliant SMTP, will
  be sent correctly, and will be properly decoded by the
  recipient. But the user trying to edit the reply would likely be
  unable to read or edit that field in its encoded form.

Emacs client features
---------------------

* **_Show the last few lines of citations as well as the first few lines_**

  It's often the case that the last sentence of a citation is what is
  being replied to directly, so the last few lines are often much more
  important. The number of lines shown at the beginning and end of any
  citation can be configured, (notmuch-show-citation-lines-prefix and
  notmuch-show-citation-lines-suffix).

* **_The '+' and '-' commands in the search view can now add and remove
  tags by region_**

  Selective bulk tagging is now possible by selecting a region of
  threads and then using either the '+' or '-' keybindings. Bulk
  tagging is still available for all threads matching the current
  search with the '*' binding.

* **_More meaningful buffer names for thread-view buffers_**

  Notmuch now uses the Subject of the thread as the buffer
  name. Previously it was using the thread ID, which is a meaningless
  number to the user.

* **_Provide for customized colors of threads in search view based on tags_**

  See the documentation of notmuch-search-line-faces, (or us "M-x
  customize" and browse to the "notmuch" group within "Applications"
  and "Mail"), for details on how to configure this colorization.

Build-system features
---------------------

* **_Add support to properly build libnotmuch on Darwin systems (OS X)_**

* **_Add support to configure for many standard options_**

  We include actual support for:

	    --includedir --mandir --sysconfdir

  And accept and silently ignore several more:

	    --build --infodir --libexecdir --localstatedir
	    --disable-maintainer-mode --disable-dependency-tracking

* **_Install emacs client in "make install" rather than requiring a
  separate "make install-emacs"_**

* **_Automatically compute versions numbers between releases_**

  This support uses the git-describe notation, so a version such as
  0.1-144-g43cbbfc indicates a version that is 144 commits since the
  0.1 release and is available as git commit "43cbbfc".

* **_Add a new "make test" target to run the test suite and actually
  verify its results_**
