This is incompatible change for DB - API users. This *isn't* incompatible change for query API users. It - means that users who just use :doc:`/reference/commands/select` - aren't affected. Use the following code that works with both older - and newer Groonga: - - .. code-block:: c - - grn_obj *score; - double score_value; - - if (score->header.domain == GRN_DB_FLOAT) { - score_value = GRN_FLOAT_VALUE(score); - } else { - score_value = (double)GRN_INT32_VALUE_FLOAT_VALUE(score); - } - -* [:doc:`/reference/commands/select`] Added more strict check for - invalid drilldown parameter. -* Added :c:func:`grn_ctx_get_all_tables()`.

See :doc:`/reference/scorer` - for details. -* [incompatible] Custom score function feature introduced API and ABI - incompatibilities in DB API layer. If you're using - :c:type:`grn_search_optarg`, please check that your code initializes - your :c:type:`grn_search_optarg` by ``0`` like the following: - - .. code-block:: c - - grn_search_optarg options; - memset(&options, 0, sizeof(grn_search_optarg)); - - If your code do the above thing, your code is API compatible and ABI - incompatible. You just need to rebuild your code without - modification. - - If your code doesn't the above thing, you need to added the above - thing to your code. - -* Added the following predicates that check :c:type:`grn_obj` type to - DB API: - - * :c:func:`grn_obj_is_table()` - * :c:func:`grn_obj_is_proc_proc()` - * :c:func:`grn_obj_is_function_proc()` - * :c:func:`grn_obj_is_selector_proc()` - * :c:func:`grn_obj_is_scorer_proc()` - -* [experimental] Supported skipping posting list when searching - popular term and rare term at the same time.

[GitHub#283] - [Reported by Tasuku SUENAGA] -* Dropped Visual Studio 2010 support. -* [experimental][mecab] Supported chunked tokenization. This feature - is a workaround for MeCab's "too long sentense" error. Specify - ``yes`` to ``GRN_MECAB_CHUNKED_TOKENIZE_ENABLED`` environment - variable to enable it. By this configuration, Groonga splits a long - text (8192 bytes over text by default) into small chunks and passes - each chunk to MeCab. By this process, the above error isn't - occurred. Additionally, you can customize chunk threshold bytes by - ``GRN_MECAB_CHUNK_SIZE_THRESHOLD`` environment variable. Note that - ``,``, ``.``, ``!``, ``?``, ``U+3001 IDEOGRAPHIC COMMA``, ``U+3002 - IDEOGRAPHIC FULL STOP``, ``U+FF01 FULLWIDTH EXCLAMATION MARK`` and - ``U+FF1F FULLWIDTH QUESTION MARK`` are treated as chunk delimiter - characters. -* Supported ``--pid-file`` in server mode of - :doc:`/reference/executables/groonga`. -* [groonga-httpd] Supported graceful stop to clean Groonga.

It means that wrong - search result is returned. If you satisfy all of the following - conditions, this bug is occurred: - - * Multiple indexes are available. - * The first defined index or the last defined index are - multi-column indexes. - * When both of the first defined index and the last defined index are - multi-column indexes, source column orders are different in them. - -* Fixed a bug that passing Groonga command line to - :doc:`/reference/executables/groonga` from shell command line style - usage always returns ``0`` as exit code. For example, ``groonga - DB_PATH nonexistent_command`` always returned ``0`` as exist code. -* Fixed a bug that plugin path may be broken when two or more plugins - registered.
