+## 0.9.0: 2015-09-29
+
+You can update to 0.9.0 from 0.8.0 by override install and executing the following SQL:
+
+```sql
+ALTER EXTENSION pgroonga UPDATE;
+```
+
+You don't need to re-create `pgroonga` indexes.
+
+### Improvements
+
+  * Supported `jsonb`. You can use `@>` operator like GIN index for `jsonb`. `@>` operator works like GIN index for `jsonb`. It's compatible. You can also use `@@` operator. It's PGroonga original operator. It's more flexible.
