# Upgrade Notice
## Known Issues
- 请勿使用 JDK11 作为 BE 的运行时 JDK，会导致 BE Crash。
## Behavior Changed
1. BE 配置项 `high_priority_flush_thread_num_per_store` 默认值由 1 改成 6 (#14775)，以提升 Routine Load 的写入效率。
2. FE 配置项 `enable_new_load_scan_node` 默认值改为 true。(#14808)
将使用新的 File Scan Node 执行导入任务。对用户无影响。
3. 删除FE 配置项 `enable_multi_catalog`。
Multi-Catalog 功能默认开启。
4. Decimal v3 精度显示变化。
当用户使用 Decimal V3 类型时，将按照实际定义精度返回结果。并且支持函数变换的精度推导。
5. 默认强制开启向量化执行引擎 (#15213)
会话变量 `enable_vectorized_engine` 将不再生效。默认开启。如需重新生效，需将 FE 配置项 `disable_enable_vectorized_engine` 设为 false，并重启 FE，以重新生效 `enable_vectorized_engine`。
