+# Release 1.4.0
+
+## Key Features
+
+| Area             | Feature                                                      |
+| ---------------- | ------------------------------------------------------------ |
+| Star Tree        | 1. Update APIs to support creating star tree cube for jdbc connectors<br/>2. Implemented support for Clickhouse connector, support for additional JDBC based connectors will be added in the future<br/>3. Bug fixes |
+| Heuristic Index  | 1. Added support for UPDATE INDEX (see docs for details)<br/>2. Added index size, memory usage and disk usage info in SHOW INDEX<br/>3. Add mmap cache support for Bloom Index to reduce memory usage (enabled by default, see docs for details)<br/>4. Dropping a table will now also drop any indexes associated with it<br/>5. Index is now automatically load after creation (enabled by default, see docs for details) |
+| Memory Connector | Fixed several important bugs to handle large data sets, and address incorrect results that occasionally occur for specific operators. |
+| Task Recovery    | Fixed several important bugs to address data inconsistency issues that occasionally occur during high concurrency, and during worker failures. |
+| OLK-on-Yarn      | Support deploying an openLooKeng cluster on yarn. The openLooKeng cluster can be deployed with a single coordinator, and multiple workers. |
+| Low Latency      | 1. Optimized the Stats calculation for point queries which don't contain join to speed up low latency queries<br/>2. Added adaptive split grouping to enhance high concurrency query throughput<br/>3. Support non-equality dynamic filters to speed up queries having predicates like <, >, <= & >= |
+| Kylin Connector  | Support read operations to the Kylin datasource              |
+
+## Known Issues
+
+| Category      | Description                                                  | Gitee issue                                                  |
+| ------------- | ------------------------------------------------------------ | ------------------------------------------------------------ |
+| Task Recovery | Concurrent CTAS, some SQL statements report the error "HiveSplitSource is already closed." | [144QYL](https://e.gitee.com/open_lookeng/issues/list?issue=I44QYL) |
+|               | An error occurs when the CTA creates a transaction table and inserts data"Unsuccessful query retry" | [I44RQJ](https://e.gitee.com/open_lookeng/issues/list?issue=I44RQJ) |
+| OLK-on-Yarn   | Multiple small openLooKeng clusters are started in the Hadoop cluster, but all openLooKeng cluster processes are on the same node. As a result, the openLooKeng cluster fails to be started | [I4BP5A](https://e.gitee.com/open_lookeng/issues/list?issue=I4BP5A) |
+|               | When multiple openLooKeng clusters are started, an error is reported when access some cluster CLI | [I4BY6Z](https://e.gitee.com/open_lookeng/issues/list?issue=I4BY6Z) |

+| --------------------- | ------------------------------------------------------------ |
+| Star Tree             | 1. 更新APIs支持jdbc 连接器使用cube<br/>2. 支持Clickhouse连接器使用cube，其它jdbc connector在将来支持<br/>3. 问题修复 |
+| 启发式索引            | 1. 支持UPDATE INDEX（详细见文档）<br/>2. SHOW INDEX中增加index大小，内存和磁盘占用信息<br/>3. Bloom index增加nmap cache来减少内存使用（默认打开，详细见文档）<br/>4. 支持DROP TABLE同时删除index<br/>5. 支持创建index后自动加载index（默认打开，详细见文档） |
+| Memory 连接器         | 修复了几个重要的错误，以解决大型数据集和特定运算符偶尔发生的错误结果 |
+| Task Recovery         | 修复了几个重要的错误，以解决高并发和worker节点故障期间偶尔发生的数据不一致问题 |
+| Yarn上部署openLooKeng | 支持Yarn上部署openLooKeng集群。当前支持部署单coordinator和多worker节点部署 |
+| 低时延                | 1. 优化不包含join的点查sql的stats计算，加快低时延查询的速度<br/>2. 新增自适应分片分组，提升高并发查询吞吐量<br/>3. 支持非等式动态筛选器，以加快具有<、>、<= & >=等谓词的查询速度 |
+| Kylin 连接器          | 支持对kylin数据源的读操作                                    |
