# News

## 4.0.6: 2026-04-07 {#version-4-0-7}
## 4.0.7: 2026-06-02 {#version-4-0-7}

### Improvements

#### [[Ubuntu][ubuntu]] Added support for for Ubuntu 24.06 (Resolute Raccoon)

#### Added an option for indexing larger-scale data

Internally, PGroonga indexes are created as a Groonga table.
PGroonga adds index to this table.
By default, this table is created in `TABLE_PAT_KEY`.

By default, The total key size of Groonga's `TABLE_PAT_KEY` is 4GiB.
While this is usually sufficient, environments wite large data may throw a "total key size is over" error when adding data.

This improvement introduces a new mode that the total key size of Groonga's `TABLE_PAT_KEY` from 4 Gib to 1 TiB.
This feature can be enables using the `lexicon_flags_mapping` option as below:


```sql
CREATE TABLE memos (
content text
);

CREATE INDEX pgrn_index ON memos
USING pgroonga (content)
WITH (lexicon_flags_mapping = '{
"content": ["LARGE"]
}');
```

Currently, only `LARGE` can be specified for this option.

### Fixes

#### Fixed a bug where PGroonga for Windows was built in debug mode

[GH-954]( https://github.com/pgroonga/pgroonga/issues/954 )[Reported by r-setoyama]

If PGroonga was built in debug mode, it required the debug runtime DLLs when loaded.
However, these debug runtime DLLs do not exist in a standard Windows environment.

As a result, PGroonga for Windows may fail to start up.
