+## Features
+
+### Support ODBC Sink in Vectorized Engine.
+
+This feature is enabled in non-vectorized engine but it is missed in vectorized engine in 1.1. So that we add back this feature in 1.1.1.
+
+### Simple Memtracker for Vectorized Engine.
+
+There is no memtracker in BE for vectorized engine in 1.1, so that the memory is out of control and cause OOM. In 1.1.1, a simple memtracker is added to BE and could control the memory and cancel the query when memory exceeded.
+
+## Improvements
+
+### Cache decompressed data in page cache.
+
+Some data is compressed using bitshuffle and it costs a lot of time to decompress it during query. In 1.1.1, doris will decompress the data that encoded by bitshuffle to accelerate query and we find it could reduce 30% latency for some query in ssb-flat.
+
+## Bug Fix
+
+### Fix the problem that could not do rolling upgrade from 1.0.(Serious)
+
+This issue was introduced in version 1.1 and may cause BE core when upgrade BE but not upgrade FE.
+
+If you encounter this problem, you can try to fix it with [#10833](https://github.com/apache/doris/pull/10833).
+
+### Fix the problem that some query not fall back to non-vectorized engine, and BE will core.
+
+Currently, vectorized engine could not deal with all sql queries and some queries (like left outer join) will use non-vectorized engine to run. But there are some cases not covered in 1.1. And it will cause be crash.
+
+### Compaction not work correctly and cause -235 Error.
+
+One rowset multi segments in uniq key compaction, segments rows will be merged in generic_iterator but merged_rows not increased. Compaction will failed in check_correctness, and make a tablet with too much versions which lead to -235 load error.
+
+### Some segment fault cases during query.

+## 新增功能
+
+### 向量化执行引擎支持 ODBC Sink。
+
+在 1.1.0 版本的向量化执行引擎中 ODBC Sink 是不支持的，而这一功能在之前版本的行存引擎是支持的，因此在 1.1.1 版本中我们重新完善了这一功能。
+
+### 增加简易版 MemTracker
+
+MemTracker 是一个用于分析内存使用情况的统计工具，在 1.1.0 版本的向量化执行引擎中，由于 BE 侧没有 MemTracker，可能出现因内存失控导致的 OOM 问题。在 1.1.1 版本中，BE 侧增加了一个简易版 MemTracker，可以帮助控制内存，并在内存超出时取消查询。
+
+完整版 MemTracker 将在 1.1.2 版本中正式发布。
+
+
+## 改进
+
+### 支持在 Page Cache 中缓存解压后数据。
+
+在 Page Cache 中有些数据是用 bitshuffle 编码方式压缩的，在查询过程中需要花费大量的时间来解压。在 1.1.1 版本中，Doris 将缓存解压由 bitshuffle 编码的数据以加速查询，我们发现在 ssb-flat 的一些查询中，可以减少 30% 的延时。
+
+## Bug 修复
+
+### 修复无法从 1.0 版本进行滚动升级的问题。
+
+这个问题是在 1.1.0 版本中出现的，当升级 BE 而不升级 FE 时，可能会导致 BE Core。
+
+如果你遇到这个问题，你可以尝试用 [#10833](https://github.com/apache/doris/pull/10833) 来修复它。
+
+### 修复某些查询不能回退到非向量化引擎的问题，并导致 BE Core。
+
+目前，向量化执行引擎不能处理所有的 SQL 查询，一些查询（如 left outer join）将使用非向量化引擎来运行。但部分场景在 1.1.0 版本中未被覆盖到，这可能导致 BE 挂掉。
+
+### Compaction 不能正常工作，导致 -235 错误。
+
+在 Unique Key 模型中，当一个 Rowset 有多个 Segment 时，在做 Compaction 过程中由于没有正确的统计行数，会导致Compaction 失败并且产生 Tablet 版本过多而导致的 -235 错误。
+
+### 在查询过程中出现了一些分段故障。
