+## 1.0.0: 2015-10-29
+
+It's the first major release!!!
+
+You can update to 1.0.0 from 0.9.0 by override install and executing the following SQL:
+
+```sql
+ALTER EXTENSION pgroonga UPDATE;
+```
+
+You don't need to re-create `pgroonga` indexes.
+

+  * Supported index only scan.
+
+  * Supported regular expression search by `@~`. [groonga-dev,03563] [Reported by Hiroaki Tachikawa]
