5.0.2: 2015-05-18 {#version-5-0-2}

Improvements

Added {Groonga::Plugin.ruby_suffix}.
{Groonga::Hash} is used as the default table type when :key_type is specified in {Groonga::Schema}. {Groonga::Array} was used as the default table type. It's a backward incompatible change.

Improvements

Supported Groonga 4.0.8. Groonga 4.0.7 or older aren't supported.

Accepted string for integer, unsigned integer and float type key.

4.0.6: 2014-11-06 {#version-4-0-6}

4.0.5: 2014-10-05 {#version-4-0-5}

Improvements

[windows] Added cross build task.
Added {Groonga::DoubleArrayTrie#update}. [GitHub#24] [Patch by Masafumi Yokoyama]
Added {Groonga::Record#rename}.
[windows] Disabled debug flags.

Fixes

Added :id => true option to {Groonga::Table::KeySupport#delete}. Groonga::Table::KeySupport#delete accepts both ID and key. If passed value is integer, it is handled as ID. But we can use Int32 as key. In the case, we can't delete a record by key. Therefore, we added Groonga::Table::KeySupport#delete(id, :id => true) API. It introduces a backward incompatibility, but it is OK because the current API is a bug.

Thanks

Masafumi Yokoyama

Added sources information to {Groonga::IndexColumn#inspect}.
Enabled with_section flag for multiple column index by default. See {Groonga::Schema::TableDefinition#index}.
Enabled with_position flag for index of a table that has a default tokenizer by default. You need to specify :with_position => false explicitly to disable with_position flag for TokenDelimit. TokenDelimit is a tokenizer that doesn't need with_position flag. See {Groonga::Schema.create_table}.

Fixes

Reduced build failure by automatically Groonga build. [Reported by SHIMADA Koji]
Added groonga-database-inspect command that inspects passed database. [Suggested by Genki Takiuchi]
{Groonga::Database#tables} ignores missing objects rather than raising an exception. Because the method is interested in only existing tables.

$ cat index-dump.sdf
  table_create --name Video --flags TABLE_HASH_KEY --key_type UInt32
  table_create --name Tag --flags TABLE_HASH_KEY --key_type ShortText
  column_create --table Video --name title --flags COLUMN_SCALAR --type ShortText

$ groonga --file index-dump.sdf -n index-dump.db
$ groonga-index-dump --output-directory=path/to/index/ index-dump.db
$ cd path/to/index/
$ ls Tag.index_tags
  Baseball.dump  IT.dump       Server.dump  Sports.dump  groonga.dump
$ cat path/to/index/Tag.index_tags/groonga.dump

```
Returned Groonga::Array instead of Array by Table#sort. [GitHub: #8][Suggested by Genki Takiuchi] CAUTION: This is backward incompatible change. You need to use record.value to get the original record. The following code shows how to use old style:
```
result_since_2_1_0 = table.sort(["sort_key"])
result_before_2_1_0 = result_since_2_1_0.collect do |record|
  record.value
end
```
