--------------------------

Improvements
^^^^^^^^^^^^

* [windows] Supported Groonga with mruby on Windows.

* Added :ref:`token-filter-stop-word` token filter plugin.
  It treats records of ``is_stop_word`` column as actual stop words.
* [doc] Added :doc:`/client` section which introduces link to client libraries.
  [GitHub#210] [Patch by Naoya Murakami]
* [doc] Reconstructed documentation. :doc:`/reference/suggest` and
  :doc:`/reference/operations/geolocation_search` are grouped under :doc:`/reference`.

* Added :doc:`/reference/function/in_values`. We recommends to use it
  instead of ``==`` and ``OR`` combinations ( ``((COLUMN == "a") OR
  (COLUMN == "b") OR (COLUMN == "c"))`` ) because of better
  performance.
* [load] Supported to update existing record in ``TABLE_NO_KEY`` by
  specifying a record by ``_id``.
* Added :ref:`token-filter-stem` token filter plugin. It provides
  stemming feature.  To use this token filter, you need to install
  `libstemmer <http://http://snowball.tartarus.org/>`_ library.
* [doc] Added :doc:`/reference/token_filters` documentation.

Release 4.0.6 - 2014/09/29
--------------------------

Improvements
^^^^^^^^^^^^

* [deb] Updated to follow the rule about machine-readable
  debian/copyright file. [Reported by Hideki Yamane]
* [deb][rpm] Changed to use signal instead of HTTP to control nginx.
  This way meets nginx style init script.
* [doc] Updated English documentation about [ :doc:`/reference/executables` ].
  [GitHub#196] [Patch by Masafumi Yokoyama]
* [OS X] Added missing sphinx error message for Homebrew users.
  [GitHub#198] [Patch by cosmo0920]
* [mruby] Query optimizer by mruby became a practical for some range select query.
  For example, mruby optimizer overhead is negligible enough for query such as
  "between(X, 0, 'exclude', 100, 'include')" - "X > 0 && X <= 100".
* [doc] Changed to recommend GitHub for reporting issues.
  Until now, Redmine account must be approved by administrator, so you can not
  report at feel free. [GitHub#202] [Patch by cosmo0920]
* [doc] Translated C API document. [GitHub#203] [Patch by NOKUBI Takatsugu]
* Supported to customize similarity threshold by ``'*S10"..."'`` syntax.
* Added source column validation to
  :doc:`/reference/commands/column_create`.  If source column doesn't
  exist, :doc:`/reference/commands/column_create` returns ``false`` and
  column isn't created.
* [debian] Dropped Debian jessie and sid support.

Fixes
^^^^^

* Fixed a bug that similar search doesn't use IDF (Inverse Document Frequency)
  for choosing target tokens.
  In the previous versions, it used token ID instead of IDF.
  [groonga-dev,02731] [groonga-dev,02754] [Reported by Satoshi Mitani, warp kawada]
* Fixed a crash bug when deleting a record.
  If the table of the record has ``_key`` and ``_key`` is
  indexed from two or more index columns, deleting causes a crash.
* Fixed compiler warning about unused variable 'e'. [GitHub#197] [Patch by cosmo0920]
* [fedora][httpd] Fixed service start failure without log directory.
* [mruby] Fixed build error with ``--disable-mruby``.
  [GitHub#200] [Patch by cosmo0920]
* Fixed build warning about CMP0014 for MariaDB bundled Mroonga package.
  [GitHub#201] [Patch by cosmo0920]
* Fixed a bug that "*" is parsed as prefix search with empty string.
  [groonga-dev,02796] [Reported by Kazuhiko]
* [httpd] Updated bundled nginx version to the latest mainline (1.7.5).
