+
+* Reduced log levels of logs for developers.
+
+* Flushed pending changed on creating new database. It guards database
+  from crash.
+
+* [``grn_geo_table_sort()``] Added a new API that sorts table by
+  geometry index.
+
+* [experimental] Added expression rewrite mechanism. You can write
+  custom expression rewriter by mruby. Expression rewriter can be used
+  for optimizing an expression, changing conditions in an expression
+  and so on.
+
+* [experimental] Added database global configuration mechanism. You
+  can put configurations (key and value pairs) into database. For
+  example, it will be used in :ref:`token-filter-stop-word` to custom
+  column name from ``is_stop_word``.
+
+* [``grn_conf_set()``] Added a new API that sets a configuration.
+
+* [``grn_conf_get()``] Added a new API that gets a configuration.

+
+* [Windows][CMake] Supported building bundled MeCab.
+  [groonga-dev,03562][Reported by Sato]
+
+* [``schema``] Added a new command that returns schema. Schema is
+  consists with loaded plugins, loaded tokenizers, loaded normalizers,
+  loaded token filters, defined tables and defined columns.
+
+* [:c:func:`grn_plugin_win32_base_dir()`] Deprecated. Use
+  :c:func:`grn_plugin_windows_base_dir()` instead.
+
+* [:c:func:`grn_plugin_windows_base_dir()`] Renamed from
+  :c:func:`grn_plugin_win32_base_dir()`.
+
+* [``grn_obj_is_type()``] Add a new API that returns true when the
+  passed object is a type object.
+
+* [``grn_obj_is_tokenizer_proc()``] Add a new API that returns true
+  when the passed object is a tokenizer object.
+
+* [``grn_obj_is_normalizer_proc()``] Add a new API that returns true
+  when the passed object is a normalizer object.
+
+* [``grn_obj_is_token_filter_proc()``] Add a new API that returns true
+  when the passed object is a token filter object.
+
+* [``grn_ctx_get_all_types()``] Add a new API that returns all type
+  objects in database.
+
+* [``grn_ctx_get_all_tokenizers()``] Add a new API that returns all
+  tokenizer objects in database.
