Release 4.0.9 - 2014-12-29
--------------------------

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

* [:doc:`/reference/executables/groonga-httpd`] Marked as stable.
* [doc] Described about ``groonga-token-filter-stem`` package.
  [GitHub#259] [Patch by Masafumi Yokoyama]
* [build] Supported ``make install`` without ``make``.
  [Reported by akira yamada]
* [experimental] Added :doc:`/reference/commands/request_cancel`
  command that cancels running request.
* [experimental] Added :c:func:`grn_db_recover()`.
* Supported indexing vector of fixed size data such as vector of
  ``UInt64``.
  [groonga-dev,03014] [Reported by funa 1g]
* [experimental] Added :doc:`/reference/executables/grndb`.
* [deb] Supported armhf architecture.
* [:doc:`/reference/executables/groonga-server-http`] Supported HEAD.
* [doc] Updated :doc:`/contribution/documentation/introduction`.
  [GitHub#270] [Patch by Yuya TAMANO]
* [doc] Updated :doc:`/install/others`.
  [GitHub#271] [Patch by Hiroshi Hatake]
* [:ref:`token-filter-stem`] Supported token that consists with only
  upper-case alphabets, digits, ``-`` and ``'``. It means that
  :ref:`token-filter-stem` can work with MySQL compatible normalizers.
* [:doc:`/reference/commands/truncate`] Supported column.
* [:doc:`/reference/commands/truncate`] Changed parameter name to
  ``target_name`` from ``table``. ``table`` parameter can be used for
  backward compatibility but it shouldn't used for newly written code.
* Exported :c:func:`grn_column_truncate()`.
* Added :doc:`/reference/commands/lock_clear`.
* Marked :doc:`/reference/commands/clearlock` deprecated.
* [backward incompatible] Stopped to set world writable permission for
  newly created files on ``umask(0)`` environment such as daemoned
  :doc:`/reference/executables/groonga-httpd`. It's a backward
  incompatible change but done because the previous behavior has
  a security risk.

  [groonga-dev,02942] [Reported by kashihara]
