Release 4.1.1 - 2015-01-29
--------------------------
Improvements
^^^^^^^^^^^^
* [windows] Improved to show error message instead of
error code. It's easy to understand.
* [experimental][windows] Supported small start file size for database file.
In previous versions, Groonga consumed larger initial file
size on windows in contrast to UNIX like environment.
To enable this feature, use ``GRN_IO_VERSION=1`` environment
variable. This feature isn't enabled by default because it is in experimental stage.
* Supported ``SUM``, ``MIN``, ``MAX``, ``AVG`` feature for drilldown.
This feature is supported by extending newer drilldown syntax which supports label.
Specify ``SUM``, ``MIN``, ``MAX`` or ``AVG`` for :ref:`select-drilldown-calc-types`
and target column for :ref:`select-drilldown-calc-target`.
The return value is calculated based on drilldown result in group.
* [experimental] Added ``--with-jemalloc`` option to use ``jemalloc`` for ``malloc()/free()``.
It'll improve performance on multi-threading usage. For example, the performance
of :doc:`/reference/executables/groonga` or `Mroonga <http://mroonga.org/>`__ will be improved.
Note that this feature doesn't affect to :doc:`/reference/executables/groonga-httpd` because
groonga-httpd uses multi-process model instead of multi-threading.
* groonga-httpd: Supported long error message over 2048 bytes.
By this change, long error message (>2048) is not truncated.
* groonga-httpd: Supported streaming dump functionality.
Fixes
^^^^^
* Fixed mismatch between error code and error message when
``strerror()`` is failed. There was a case that Groonga shows
incorrect error code as syscall error.
* Fixed to show errno in error message when unknow error is occurred.
* [windows] Fixed to return proper error code.
* Fixed a bug that there is only one section for multi-column index for
:ref:`select-match-columns`, it doesn't return correct search results.
For example, consider the case that there is multi-column index which is
named as ``memo_index`` for ``title`` column and ``content`` column.
Thus, this bug occurs when ``memo_index[0]`` which means index
for ``title`` column is specified for :ref:`select-match-columns`.
* mecab: Added workaround for ``mecab_strerror(NULL)`` on MeCab 0.993.
Without this workaround, Groonga aborts if there is no MeCab
dictionary. [Reported by Shuhei Tanuma]
* groonga-httpd: Fixed a bug that custom log file is ignored.
* groonga-httpd: Fixed a bug that empty dump doesn't return.
Thanks

.. _release-4-1-0:
Release 4.1.0 - 2015-01-09
--------------------------
It's a bug fix release of 4.0.9.
If you have already upgraded to 4.0.9, please upgrade to 4.1.0. And
re-create your all indexes. You can re-create your indexes by removing
and re-creating your indexes such as::
column_remove TABLE INDEX_COLUMN
column_create TABLE INDEX_COLUMN COLUMN_INDEX|...
.. seealso::
* :doc:`/reference/commands/column_remove`
* :doc:`/reference/commands/column_create`
.. note::
If you didn't change your indexes by Groonga 4.0.9, you don't need
to re-create your indexes. "change" means "add", "remove" and
"update". If you use your indexes only for "search" by Groonga
4.0.9, you don't need to re-create your indexes.
Fixes
^^^^^
* Fixed a bug that index may be broken. But the following bug fixed in
Groonga 4.0.9 is re-appeared.
* Fixed a crash bug that may be occurred by deleting or updating many
indexed values at once.

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.

Release 4.0.8 - 2014/11/29
--------------------------
Improvements
^^^^^^^^^^^^
* [deb] Supported Ubuntu 12.04 again because Travis-CI runs on it.
* [mruby] Supported pretty print - ``"pp"`` for debugging. And supported to
show internal objects more descriptive format when inspecting it.
* Supported full text search query without index if one column is specified
for ``--match_columns`` even though sequential search is executed
by ``--query`` and ``--match_columns`` combination.
[groonga-dev,02902] [Reported by Atsushi Shinoda]
* [experimental] :doc:`/reference/functions/in_values` supports auto sequential
search mode. There is a case that sequential search is faster than index search when
the number of narrowed down records is small enough in contrast to
the number of expected records to narrow down by ``in_values`` with
``AND`` operation which use indexes.
The value of ``GRN_IN_VALUES_TOO_MANY_INDEX_MATCH_RATIO`` is used as
threshold whether Groonga execute sequential search or search with indexes in
such a case.
* [mruby] Supported to load relative path of script.
* Supported test suite to write query optimizer test more easily with
mruby enabled build.
* Supported offline index construction for token filters.
[GitHub#239] [Patch by Naoya Murakami]
* [experimental] :doc:`/reference/functions/between` supports auto sequential search mode.
Use the value of ``GRN_BETWEEN_TOO_MANY_INDEX_MATCH_RATIO`` as threshold.
Basic concept is similar to ``GRN_IN_VALUES_TOO_MANY_INDEX_MATCH_RATIO``.
* [experimental] Supported multiple drilldowns for :doc:``/reference/command/select``
command. The syntax is extended to support this feature. The new one is
``--drilldown[LABEL1].keys COLUMN1,COLUMN2`` for keys,
``--drilldown[LABEL1].output_columns _value.COLUMN1,_value.COLUMN2,_nsubrecs`` for output columns.
In the previous versions, a client application must implement by oneself for drilldown
by multiple keys. Use ``_key[N]`` for ``--drilldown[LABEL1].output_columns`` to show
original value of key in records.
* Supported to search ``'reference_column @ "query"'`` without index.
* [experimental] Added :doc:`/reference/commands/range_filter` command. It is faster than select
command to fetch specific range of records in most cases, because it doesn't returns
the number of matched records. There are limitations which doesn't support drilldown and so on.
Thus, ``range_filter`` is suitable for extracting first ``N`` records in specific range for ranking
or something else.
* [httpd] Supported ``groonga-httpd`` on windows.
* Supported vector column for drilldown.
* [deb] Changed ``groonga-httpd`` as default HTTP server package.
``groonga-server-http`` is deprecated. Note that :doc:`/reference/executables/groonga-server-http`
functionality itself is still exists in Groonga. If you just want to use simple HTTP server
in traditional way, specify proper arguments by command line for :doc:`/reference/executables/groonga`.
* Added configuration file for Windows CI on AppVeyor.
[groonga-dev,02970,02981] [Patch by Hiroshi Hatake]
Fixes
^^^^^
* [doc] Fixed duplicated execution example path about
:doc:`/reference/commands/table_create`.
[GitHub groonga.org#14] [Reported by Masafumi Yokoyama]
* Fixed a bug that nested indexed full text search against ``X._key``
returns empty results.
* Fixed flags parameter which is strict in BSD ``mkostemp(3)``.
[GitHub#240] [Patch by Jun Kuriyama]
* Fixed a bug that select command reports invalid value type (table)
as index column value type. It was fixed to ``UInt32``.
Note that it affects only the value of response header.
The search results is not changed at all.
* Fixed a bug that compare operations such as ``<``, ``<=``, ``>``, ``>=``, ``!=`` with
Time and String type returns invalid results.
* Fixed a bug that prefix search can't be executed against single character such as
``"x*"``. [GitHub#242] [Patch by Naoya Murakami]
* Fixed a memory leak on drilldown ``ShortText`` value with ``--filter``.
* Fixed missing ``","`` for ``"DDL:set_token_filters"`` log.

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.

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.

Fixes
^^^^^
* Fixed a crash bug that an object in grn_expr is used after it is freed.
Normally Groonga server users aren't affected this bug. This bug mainly affects Rroonga users.
Because this bug is occured by specifying column name including pseudo column name -
such as '_key' - Rroonga users may use the usage.
* Fixed not to execute unexpected cascade delete which is introduced Groonga 3.0.8 release.
If source's range and index's domain are different, Groonga doesn't execute cascade delete.

Release 3.1.2 - 2014/01/29
--------------------------
Improvements
^^^^^^^^^^^^
* [doc] Updated to caplitalized "Groonga" terms in documentation. [Patch by cosmo0920] [GitHub#136, #137, #138, #139, #140, #141, #142, #143, #144, #145, #146, #147, #148, #149, #150, #151]

[groonga-dev,02017] [Suggested by yoku]
* [doc] Added description about the value of lock timeout.
* Enabled ``GRN_JA_SKIP_SAME_VALUE_PUT`` by default. In the previous releases, the value of
this configuration is 'no'. This change affects reducing the size of Groonga database.
* Supported multiple indexes including a nested index and multiple keywords query.
This change improves missing search results isssue when narrowing down by multiple keywords query.
* Added API to customize normalizer for snippet.
Fixes
^^^^^
* Fixed not to use index for empty query. This change enables you to search even though empty query.
Note that this means that there is performance penalty if many empty records exist.
[groonga-dev,02052] [Reported by Naoya Murakami]
* Fixed the behaviour about return value of "X || Y" and "X && Y" for adjusting to ECMAScript.
In "X || Y" case, if either X or Y satisfy the condition, it returns X itself or Y itself instead of 1 or 0.
* In "X && Y" case, if X and Y satisfy the condition, it returns X itself instead of 1.
if X doesn't satisfy the condition, it returns false instead of 0.
* Fixed to return null when no snippet is found. This change enables you to set the default value
of :doc:`/reference/functions/snippet_html`. In such a purpose, use "snippet_html(XXX) || 'default value'".
