29+
30+
[GH-771](https://github.com/pgroonga/pgroonga/pull/771)
31+
32+
PostgreSQL 18以降で、PostgreSQLのプランナはPGroongaをソート可能なインデックスとして認識できるようになりました。
33+
34+
`WHERE ... ORDER BY ... LIMIT`のようなクエリで、PGroongaで絞り込みとソート済みのレコードをPostgreSQLに返すことができます。
35+
これにより、多くのレコードがマッチするときの応答時間の改善が見込めます。

39+

44+

### Improvements
11+
12+
#### Added support for PostgreSQL 18
13+
14+
We now provided packages for PostgreSQL 18.
15+
16+
#### [[Debian][debian]] Added support for Debian GNU/Linux trixie
17+
18+
The package for Debian GNU/Linux trixie is now available.
19+
20+
#### [[AlmaLinux][almalinux]] Added support for AlmaLinux 10 package
21+
22+
We now provided official RPM packages for AlmaLinux 10.
23+
24+
#### [[AlmaLinux][almalinux]] Added support for PostgreSQL 14 with AlmaLinux 9 package
25+
26+
Previously, we didn’t provide a PGroonga package for PostgreSQL 14 on AlmaLinux 9. It’s now available.
27+
So, we now provide it.
28+
29+
#### Added support ordered index scan on PostgreSQL 18
30+
31+
[GH-771](https://github.com/pgroonga/pgroonga/pull/771)
32+
33+
On PostgreSQL 18 and later, PostgreSQL's planner can recognize PGroonga as an ordered index.
34+
35+
PGroonga can return filtered and sorted records to PostgreSQL for queries like `WHERE ... ORDER BY ... LIMIT`.
36+
This improvement may improve the response time when many rows match.
37+
38+
```sql
39+
CREATE TABLE messages (
40+
id serial,
41+
content text
42+
);
43+
44+
CREATE INDEX messages_index ON messages
45+
USING PGroonga (content, id);
46+
47+
INSERT INTO messages (content)
48+
SELECT content FROM (SELECT 'a' AS content, generate_series(0, 9999)) AS values;
