+# 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)
+
+### Optimize the import and query performance of JSONB type
+
+Optimize the import and query performance of JSONB type. [#15219](https://github.com/apache/doris/pull/15219) [#15219](https://github.com/apache/doris/pull/15219)
+
+### Stream load supports quoted csv data
+
+Search trim_double_quotes in Document:[https://doris.apache.org/en/docs/dev/sql-manual/sql-reference/Data-Manipulation-Statements/Load/STREAM-LOAD](https://doris.apache.org/en/docs/dev/sql-manual/sql-reference/Data-Manipulation-Statements/Load/STREAM-LOAD)
+
+### Broker supports Tencent Cloud CHDFS and Baidu Cloud BOS, AFS
+
+Data on CHDFS, BOS, and AFS can be accessed through Broker. [#15297](https://github.com/apache/doris/pull/15297) [#15448](https://github.com/apache/doris/pull/15448)
+
+### New function
+
+Add function `substring_index`. [#15373](https://github.com/apache/doris/pull/15373)
+
+# Bug Fix
+
+- In some cases, after upgrading from version 1.1 to version 1.2, the user permission information will be lost. [#15144](https://github.com/apache/doris/pull/15144)
+
+- Fix the problem that the partition value is wrong when using datev2/datetimev2 type for partitioning. [#15094](https://github.com/apache/doris/pull/15094)
+
+- Bug fixes for a large number of released features. For a complete list see: [PR List](https://github.com/apache/doris/pulls?q=is%3Apr+label%3Adev%2F1.2.1-merged+is%3Aclosed)
+
+# 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.
+

+在 1.2.1 版本中，Doris 团队已经修复了自 1.2.0 版本发布以来约 200 个问题或性能改进项。同时，1.2.1 版本也作为 1.2 LTS 的第一个迭代版本，具备更高的稳定性，建议所有用户升级到这个版本。
+
+
+# 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。 [#15437](https://github.com/apache/doris/pull/15437) [#12872](https://github.com/apache/doris/pull/12872)
+
+
+### 优化 JSONB 类型的导入和查询性能
+
+优化 JSONB 类型的导入和查询性能，在测试数据上约有 70% 的性能提升。 [#15219](https://github.com/apache/doris/pull/15219) [#15219](https://github.com/apache/doris/pull/15219)
+
+### Stream load 支持带引号的 CSV 数据
+
+通过导入任务参数 `trim_double_quotes` 来控制，默认值为 false，为 true 时表示裁剪掉 CSV 文件每个字段最外层的双引号。 [#15241](https://github.com/apache/doris/pull/15241)
+
+### Broker 支持腾讯云 CHDFS 和 百度云 BOS 、AFS
+
+可以通过 Broker 访问存储在腾讯云 CHDFS 和 百度智能云 BOS、AFS 上的数据。 [#15297](https://github.com/apache/doris/pull/15297) [#15448](https://github.com/apache/doris/pull/15448)
+
+### 新增函数
+
+新增函数 `substring_index`。 [#15373](https://github.com/apache/doris/pull/15373)
+
+
+
+# 问题修复
+
+- 修复部分情况下，从 1.1.x 版本升级到 1.2.0 版本后，用户权限信息丢失的问题。 [#15144](https://github.com/apache/doris/pull/15144)
+
+- 修复使用 date/datetimev2 类型进行分区时，分区值错误的问题。 [#15094](https://github.com/apache/doris/pull/15094)
+
+- 修复部分已发布功能的 Bug，具体列表可参阅：[PR List](https://github.com/apache/doris/pulls?q=is%3Apr+label%3Adev%2F1.2.1-merged+is%3Aclosed)
+
+
+# 升级注意事项
+
+### 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)
+
+- FE 配置项 `enable_new_load_scan_node` 默认值改为 true ，将使用新的 File Scan Node 执行导入任务，对用户无影响。 [#14808](https://github.com/apache/doris/pull/14808)
+
+- 删除 FE 配置项 `enable_multi_catalog`，默认开启 Multi-Catalog 功能。
+
+- 默认强制开启向量化执行引擎。会话变量 `enable_vectorized_engine` 将不再生效，如需重新生效，需将 FE 配置项 `disable_enable_vectorized_engine` 设为 false，并重启 FE。 [#15213](https://github.com/apache/doris/pull/15213)
