+## Behavior change
+- Change char function behaviour: `select char(0) = '\0'` return true as MySQL
+ - https://github.com/apache/doris/pull/30034
+- Allow exporting empty data
+ - https://github.com/apache/doris/pull/30703
+
+## New features
+- Eliminate left outer join with `is null` condition
+- Add `show-tablets-belong` stmt for analyzing a batch of tablet-ids
+- InferPredicates support In, such as `a = b & a in [1, 2] -> b in [1, 2]`
+- Optimize plan when column stats are unavailable
+- Optimize plan using rollup column stats
+- Support analyze materialized view
+- Support ShowProcessStmt Show all FE connection
+
+## Improvement and optimizations
+- Optimize query plan when column stats are unaviable
+- Optimize query plan using rollup column stats
+- Stop analyze quickly after user close auto analyze
+- Catch load column stats exception, avoid print too much stack info to fe.out
+- Select materialized view by specify the view name in SQL
+- Change auto analyze max table width default value to 100
+- Escape characters for columns in recovery predicate pushdown in JDBC Catalog
+- Fix JDBC MYSQL Catalog `to_date` fun pushdown
+- Optimize the close logic of JDBC client
+- Optimize JDBC connection pool parameter settings
+- Obtain hudi partition information through HMS's API
+- Optimize routine load job error msg and memory
+- Skip all backup/restore jobs if max allowd option is set to 0
+
+See the complete list of improvements and bug fixes on
[github](https://github.com/apache/doris/compare/2.0.4-rc06...2.0.5-rc02).

+## 行为变更
+- `select char(0) = '\0'` 返回 true，跟 MySQL 的行为保持一致
+ - https://github.com/apache/doris/pull/30034
+- Export 导出数据支持空表
+ - https://github.com/apache/doris/pull/30703
+
+## 新功能
+- 利用过滤条件中的 `is null` 谓词，将 OUTER JOIN 转换为 ANTI JOIN
+- 增加 `SHOW TABLETS BELONG` 语法用于获取 tablet 属于哪个 table
+- InferPredicates 支持 `IN`，例如：`a = b & a in [1, 2] -> b in [1, 2]`
+- 支持对物化视图收集统计信息
+- `SHOW PROCESSLIST` 支持输出连接对应的 FE
+- Export 导出 CSV 文件支持通过 `with_bom` 参数控制是否带有 Windows BOM
+
+## 改进和优化
+- 在无统计信息时优化 Query Plan
+- 基于 Rollup 的统计信息优化 Query Plan
+- 用户停止 Auto Analyze 后尽快停止统计信息收集任务
+- 缓存统计信息收集异常，避免大约太多异常栈
+- 支持在 SQL 中自定使用某个物化视图
+- JDBC Catalog 谓词下推列名字符转义
+- 修复 MySQL Catalog 中 `to_date` 函数下推的问题
+- 优化 JDBC 客户端连接关闭的逻辑，在异常时正常取消查询
+- 优化 JDBC 连接池的参数
+- 通过 HMS API 获取 Hudi 外表的分区信息
+- 优化 Routine Load 的内存占用和错误信息
+- 如果 `max_backup_restore_job_num_per_db` 参数为 0，跳过所有备份恢复任务
