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.
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.

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 'index[0]' for :ref:`select-match_columns`,
it doesn't return correct search results. For example, it occurs
when index 'memo_index' is created against multiple column -
'title,content' then 'memo_index[0]' is specified.
* 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]
