Release 4.1.1 - 2015-01-29
--------------------------

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

* [windows] Improved to show error message instead of
error code. It's easy to understand.
* [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.
* Supported sum feature for drilldown. Here is the syntax how to use it.
``select --drilldown[label].calc_type SUM --drilldown[label].calc_target target_column``
It returns drilldown result with max value in group.
* Supported ``MIN``, ``MAX``, ``AVG`` feature for drilldown. The syntax is same as
sum feature. You can specify multiple 'calc_types' at the same time.
* Added ``--with-jemalloc`` option to use ``jemalloc`` for ``malloc()/free()``.
It'll improve performance on multi-threading usage.
* groonga-httpd: Supported long error message over ``NGX_MAX_ERROR_STR``.
By this change, long error message (>=2048) is not truncated.
* [doc] Added documents about :ref:`select-drilldown-limit`,
:ref:`select-drilldown-calc-types`, :ref:`select-drilldown-calc-target` and more.

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 '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.
* http: Fixed a bug that two or more request don't have body.
* 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.
* http: Fixed a bug that body isn't returned for POST requests.

Thanks
^^^^^^

* Shuhei Tanuma
