## Release 2.1.2 - 2013-01-29

### Improvements

- Dropped experimental view feature.

- Added `grn_logger_reopen` API for custom logger. Note that `grn_logger_info` API is deprecated, use `grn_logger` API instead.

- Added `grn_default_logger_set_path()` and `grn_default_logger_get_path()` API. Note that global `grn_log_path` variable was removed. Use above API.

- Added `grn_default_query_logger_set_path()` and `grn_default_query_logger_get_path()` API. Note that global `grn_qlog_path` variable was removed. Use above API.

- Added translated documentation about Tables and Normalizers.

- [deb][rpm] Improved to install with missing dictionary when `groonga-tokenizer-mecab` package is installed.

- Supported Nested index search among related table by column index with range search. For example, you can specify ‘column1.column2…columnN <= “1988-01-04 00:00:00”’ in `--filter`.

- [rpm][fedora] Supported Fedora 18.

- [rpm][fedora] Dropped Fedora 17 support.

- [doc] Added documentation for Server packages.

- [doc] Added documentation for query.

### Fixes

## Release 2.1.1 - 2012-12-29

This is bug fix release of 2.1.0. All of 2.1.0 users should use 2.1.1 instead.

### Fixes

- Fixed a bug that `KEY_NORMALIZE` information in database that is created by groonga 2.0.8 or ealier is dropped.

## Release 2.1.0 - 2012-12-29

Caution

Use 2.1.1 instead of 2.1.0. 2.1.0 has a serious bug related `KEY_NORMALIZE`.

Caution

This release has backward incompatible changes against `table_list` and `column_list` commands. If you use own program which depends on the output results above commands, you need to support null instead of “null” string.

This release has supported `--normalizer` option, but there is side effect for this feature. If you open old version of groonga database at least once, you can not open its database by old version of groonga.

There is also another backward incompatible change agaist plugin API for tokenizer. The argument of `grn_tokenizer_query_open` API has changed. This API change affects developer of tokenizer plugin.

### Improvements

- [doc] Added documentation about Nested index search among related table by column index.

- Supported the expression as snippet_html arguments. This change enables you to use `snippet_html("STRING" + "STRING")` for example. You can specify column name or literal for “STRING”. [Reported by Tomoatsu Shimada]

- Supported to create own normalizer as a plugin.

- Moved `groonga-query-log-analyzer` as groonga-query-log RubyGems. It enables you to analyze query logs without installing groonga package.

- Supported `--normalizer` option for table_create command. This change enables you to specify normalizer plugin.

- Changed “null” string to null value as meaning for “No Object”. This is backward incompatible change and affects output results of introspection related commands such as `table_list` and `column_list`.

- Added a flag which controls behavior about normalizer as the last argument of `grn_tokenizer_query_open` API.

- Supported continuous line in Command list.

- Improved to support not only no key table, but also hash table, patricia trie and double array trie for Nested index search among related table by column index.

### Fixes

- [windows] Added missing `O_BINARY` flag to open file correctly. This change fixes the infinite loop problem about groonga HTTP server. [GitHub#47] [Patch by Shimomura Tatsuya]

- Fixed a bug that `--default-match-escalation-threshold` doesn’t accept negative value to disable functionality that is used on 検索. This fix enable you to disable search escalation. see `groonga --default-match-escalation-threshold` about details.

- Fixed a bug that `_score` after “*” is ignored in `--output_columns`.

### Thanks

## Release 2.0.9 - 2012-11-29

### Improvements

- Supported to calculate the value of distance accross border in `geo_distance` with `rectangle` as approximate type. [#1534]

- [doc] Added the GQTP specification.

- Improved to ignore non critical `getaddrinfo()` error which groonga command emits on startup. This change does not affects nomal use of groonga because it just checked whether default hostname is resolved in previous version.

- [experimental] Added `snippet_html()` function which extract keyword and surrounding text. See snippet_html about details.

- Supported to report error reason when error occured during reading table record.

- Supported to search with keyword by nested index notation ( concatinate multiple indexed column name with dot character ) if there is a relationship between multiple table with index.

- Supported to log “[tokenizer][mecab]” tag when using `TokenMecab` tokenizer.

- Supported to log “[tokenizer][kytea]” tag when using `TokenKyTea` tokenizer.

- Improved to use separated array for command error location as output results. This change is incompatibility change, but does not affects existing program.

- Added documentation for Output format.

- Added documentation for Return code of output results.

- Supported range search by using index.

### Fixes

- Fixed to use network byte order for status code of GQTP header to follow the normal network protocol convention. This change affects that groonga <= 2.0.8 client which connects to groonga server 2.0.9 or later can not show status code properly when command failed.

- Fixed a bug that UTF-8 normalization computes wrong offset which affects to return value of `snippet_html()`. This change not to insert tag of snippet into invalid location. [#1531] [Reported by Tomoatsu Shimada]

- [windows] Fixed over allocated memory access which cause segmentation fault on startup by groonga command. [#1532] [Patch by Akio Tajima]

- [windows] Fixed a bug that data stored in column couldn’t be read when total amount of data stored in column exceeds 128MB. [groonga-dev,01088] [Reported by ongaeshi]

- Fixed a bug that searching with indexed column for `Int*` and `UInt*` except `Int32/Uint32` returns invalid results.

- Fixed a bug that deleting record can be found.

- Fixed a bug that latin1 and koi8r normalizations could not process all string data if given string contains NULL character on the way.

- Fixed to return the correct default value of type when no data stored in column is referenced by `select` command.

- Fixed to exclude the value of vector column metadata in Offline index construction. This change not to contain such a metadata as search results.
