+# Improvement
+
+### Supports new type DecimalV3
+
+DecimalV3, which supports higher precision and better performance, has the
following advantages over past versions.
+
+- Larger representable range, the range of values are significantly expanded,
and the valid number range [1,38].
+
+- Higher performance, adaptive adjustment of the storage space occupied
according to different precision.
+
+- More complete precision derivation support, for different expressions,
different precision derivation rules are applied to the accuracy of the result.
+
+### Support Iceberg V2
+
+Support Iceberg V2 (only Position Delete is supported, Equality Delete will be
supported in subsequent versions).
+
+Tables in Iceberg V2 format can be accessed through the Multi-Catalog feature.
+
+### Support OR condition to IN
+
+Support converting OR condition to IN condition, which can improve the
execution efficiency in some
scenarios.[#15437](https://github.com/apache/doris/pull/15437)
[#12872](https://github.com/apache/doris/pull/12872)

+
+# Upgrade Notice
+
+### Known Issues
+
+Do not use JDK11 as the runtime JDK of BE, it will cause BE Crash.
+
+### Behavior Changed
+
+- The default value of the BE configuration item
`high_priority_flush_thread_num_per_store` is changed from 1 to 6, to improve
the write efficiency of Routine Load.
(https://github.com/apache/doris/pull/14775)
+
+- The default value of the FE configuration item `enable_new_load_scan_node`
is changed to true. Import tasks will be performed using the new File Scan
Node. No impact on users.[#14808](https://github.com/apache/doris/pull/14808)
+
+- Delete the FE configuration item `enable_multi_catalog`. The Multi-Catalog
function is enabled by default.
+
+- The vectorized execution engine is forced to be enabled by
default.[#15213](https://github.com/apache/doris/pull/15213)
+
+The session variable enable_vectorized_engine will no longer take effect.
Enabled by default.
+
+To make it valid again, set the FE configuration item
`disable_enable_vectorized_engine` to false, and restart FE to make
`enable_vectorized_engine` valid again.

+
+
+# 优化改进
+
+### 支持高精度小数 DecimalV3
+
+支持精度更高和性能更好的 DecimalV3，相较于过去版本具有以下优势：
+
+- 可表示范围更大，取值范围都进行了明显扩充，有效数字范围 [1,38]。
+
+- 性能更高，根据不同精度，占用存储空间可自适应调整。
+
+- 支持更完备的精度推演，对于不同的表达式，应用不同的精度推演规则对结果的精度进行推演。
+
+[DecimalV3](https://doris.apache.org/zh-CN/docs/dev/sql-manual/sql-reference/Data-Types/DECIMALV3)
+
+### 支持 Iceberg V2
+
+支持 Iceberg V2 (仅支持 Position Delete， Equality Delete 会在后续版本支持)，可以通过
Multi-Catalog 功能访问 Iceberg V2 格式的表。
+
+
+### 支持 OR 条件转 IN
+
+支持将 where 条件表达式后的 or 条件转换成 in 条件，在部分场景中可以提升执行效率。

+
+### 已知问题
+
+请勿使用 JDK11 作为 BE 的运行时 JDK，会导致 BE Crash。
+
+### 行为改变
+
+- BE 配置项 `high_priority_flush_thread_num_per_store` 默认值由 1 改成 6 ，以提升 Routine
Load 的写入效率。[#14775](https://github.com/apache/doris/pull/14775)
