+## 0.9.8
+
+### Improvements 
+
+- **[client-v2]** Added `Records#getSchema()` to expose table schema metadata even when query result is empty. (https://github.com/ClickHouse/clickhouse-java/pull/2777)
+
+### Bug Fixes
+
+- **[jdbc-v1, jdbc-v2]** Fixed type mapping/conversion behavior for large unsigned integer values (issue #2779), including related test coverage updates. (https://github.com/ClickHouse/clickhouse-java/issues/2779)
+
+- **[jdbc-v2]** Fixed off-by-one bug in `ArrayResultSet#next()` that could return `true` one extra time and then fail with `SQLException: No current row`. (https://github.com/ClickHouse/clickhouse-java/pull/2790)
+
+- **[jdbc-v2]** Fixed handling of malformed `SELECT`-like queries (for example, `SELECT a, FROM table`): previously, the driver could fail to read returned data when query type was not inferred before execution; now it detects a returned result set at runtime from the server response and reads it correctly. (https://github.com/ClickHouse/clickhouse-java/issues/2784)
+
+### Updated Dependencies
+
+- **[repo]** Upgraded `at.yawk.lz4:lz4-java` from `1.10.2` to `1.10.4` to pick up native performance fixes. (https://github.com/ClickHouse/clickhouse-java/pull/2778)
+
+- **[repo]** Upgraded `com.fasterxml.jackson.core:jackson-core` from `2.17.2` to `2.18.6` in `jdbc-v2`. (https://github.com/ClickHouse/clickhouse-java/pull/2767)
+
+- **[repo]** Upgraded `com.fasterxml.jackson.core:jackson-core` from `2.17.2` to `2.18.6` in `examples/client-v2`. (https://github.com/ClickHouse/clickhouse-java/pull/2766)
