+    - 增加排队处理 Coprocessor 任务的线程池以减小内存溢出几率，并增加配置项 `cop_pool_size` 和 `batch_cop_pool_size`，默认值为 `物理核数 * 2` [#1312](https://github.com/pingcap/tics/pull/1312)


In “减小内存溢出几率”, could we update “减小” to “降低”？

Yes. Changed to “降低”.

+    - 修复生成多个 join 相关 hint 可能 panic 的问题 [#22518](https://github.com/pingcap/tidb/pull/22518)
+    - 修复转换字符串为 `BIT` 类型不准确的问题 [#22420](https://github.com/pingcap/tidb/pull/22420)
+    - 修复插入 `tidb_rowid` 列时出现的 `index out of range` 报错问题 [#22359](https://github.com/pingcap/tidb/pull/22359)
+    - 修复缓存计划被错误的使用问题 [#22353](https://github.com/pingcap/tidb/pull/22353)


“修复缓存计划被错误的使用问题” looks confusing, does it mean “修复缓存计划被错误使用的问题” or “修复缓存计划被错误地使用的问题”？

The English version is "Fix a bug that the cached plan is incorrectly used". I think it should be “修复缓存计划被错误地使用的问题”.

+    - 修正 Coprocessor 中错误解析 Decimal 常量的问题
+    - 修正 Learner Read 过程中可能导致 crash 的问题
+    - 修正 TiFlash 中除 `0` 或 `NULL` 的行为与 TiDB 不一致的问题
+


line 138 to line 143, the verb "修正“ is used, while in all other notes in this document, "修复“ is used. Suggest using "修复“ consistently in this document.

+    - 修正 DDL 操作后写入的数据可能会在 compaction 后丢失的问题
+    - 修正 Coprocessor 中错误解析 Decimal 常量的问题
+    - 修正 Learner Read 过程中可能导致 crash 的问题
+    - 修正 TiFlash 中除 `0` 或 `NULL` 的行为与 TiDB 不一致的问题


In "修正 TiFlash 中除 0 或 NULL 的行为与 TiDB 不一致的问题", is "除 0 或 NULL 的行为" correct? Does it mean "除以0 或 `NULL". Would you please double check?

As confirmed with @zanmato1984, it should be "除以 0 或 NULL". However, "除 0 或 NULL" is also commonly used among programmers.
