+
+## 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 Fixes
+
+### 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.

+
+
+
+In this release, Doris Team has fixed more than 170 issues or performance
improvement since 1.1.1. This release is a bugfix release on 1.1 and all users
are encouraged to upgrade to this release.
+
+## Features
+
+### New MemTracker
+
+Introduced new MemTracker for both vectorized engine and non-vectorized engine
which is more accurate.
+
+### Add API for showing current queries and kill query
+
+### Support read/write emoji of UTF16 via ODBC Table
+
+
+
+## Improvements
+
+### Data Lake related improvements
+
+- Improved HDFS ORC File scan performance about 300%.
[#11501](https://github.com/apache/doris/pull/11501)
+
+- Support HDFS HA mode when query Iceberg table.
+
+- Support query Hive data created by [Apache Tez](https://tez.apache.org/)
+
+- Add Ali OSS as Hive external support.
+
+### Add support for string and text type in Spark Load
+
+
+### Add reuse block in non-vectorized engine and have 50% performance
improvement in some cases. [#11392](https://github.com/apache/doris/pull/11392)
+
+### Improve like or regex performance
+
+### Disable tcmalloc's aggressive_memory_decommit
+
+It will have 40% performance gains in load or query.
+
+Currently it is a config, you can change it by set config
`tc_enable_aggressive_memory_decommit`.
+
+
+## Bug Fixes
+
+### Some issues about FE that will cause FE failure or data corrupt.
+
+- Add reserved disk config to avoid too many reserved BDB-JE
files.**(Serious)** In an HA environment, BDB JE will retains as many
reserved files. The BDB-je log doesn't delete until approaching a disk limit.
+
+- Fix fatal bug in BDB-JE which will cause FE replica could not start
correctly or data corrupted.** (Serious)**
+
+### Fe will hang on waitFor_rpc during query and BE will hang in high
concurrent scenarios.

+
+## Upgrade Notes
+
+PageCache and ChunkAllocator are disabled by default to reduce memory usage
and can be re-enabled by modifying the configuration items
`disable_storage_page_cache` and `chunk_reserved_bytes_limit`.
+
+Storage Page Cache and Chunk Allocator cache user data chunks and memory
preallocation, respectively.
+
+These two functions take up a certain percentage of memory and are not freed.
This part of memory cannot be flexibly allocated, which may lead to
insufficient memory for other tasks in some scenarios, affecting system
stability and availability. Therefore, we disabled these two features by
default in version 1.1.3.
+
+However, in some latency-sensitive reporting scenarios, turning off this
feature may lead to increased query latency. If you are worried about the
impact of this feature on your business after upgrade, you can add the
following parameters to be.conf to keep the same behavior as the previous
version.
+
+```
+disable_storage_page_cache=false
+chunk_reserved_bytes_limit=10%
+```
+
+* ``disable_storage_page_cache``: Whether to disable Storage Page Cache.
version 1.1.2 (inclusive), the default is false, i.e., on. version 1.1.3
defaults to true, i.e., off.
+* `chunk_reserved_bytes_limit`: Chunk allocator reserved memory size. 1.1.2
(and earlier), the default is 10% of the overall memory. 1.1.3 version default
is 209715200 (200MB).

+
+# Behavior Changes
+
+When alias name is same as the original column name like "select
year(birthday) as birthday" and use it in group by, order by , having clause,
doris's behavior is different from MySQL in the past. In this release, we make
it follow MySQL's behavior. Group by and having clause will use original column
at first and order by will use alias first. It maybe a litter confuse here so
there is a simple advice here, you'd better not use an alias the same as
original column name.
+
+# Features
+
+Add support of murmur_hash3_64.

+## Improvements
+
+### 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.
+
+[DecimalV3](https://doris.apache.org/docs/dev/sql-manual/sql-reference/Data-Types/DECIMALV3/)
+
+### Support Iceberg V2

+## Upgrade Notices
+
+### Known Issues
+
+- Do not use JDK11 as the runtime JDK of BE, it will cause BE Crash.
+- The reading performance of the csv format in this version has declined,
which will affect the import and reading efficiency of the csv format. We will
fix it as soon as possible in the next three-digit version
+
+### 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.

+
+Reference:
[https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc/#doris](https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc/#doris)
+
+- Support to synchronize only the specified database through the
`only_specified_database` attribute.
+
+- Support synchronizing table names in the form of lowercase through
`lower_case_table_names` to solve the problem of case sensitivity of table

+- Support Hive table default partition `_HIVE_DEFAULT_PARTITION_`.
+
+- Hive Metastore metadata automatic synchronization supports notification
event in compressed format.
+
+### Dynamic Partition Improvement
+
+- Dynamic partition supports specifying the `storage_medium` parameter to
control the storage medium of the newly added partition.
+

+## Behavior Changed
+
+- For `DateV2`/`DatetimeV2` and `DecimalV3` type, in the results of
`DESCRIBLE` and `SHOW CREATE TABLE` statements, they will no longer be
displayed as `DateV2`/`DatetimeV2` or `DecimalV3`, but directly displayed as
`Date`/`Datetime` or `Decimal`.
+
+ - This change is for compatibility with some BI tools. If you want to
see the actual type of the column, you can check it with the `DESCRIBE ALL`
statement.
+
+- When querying tables in the `information_schema` database, the meta
information(database, table, column, etc.) in the external catalog is no longer
returned by default.
+
+ - This change avoids the problem that the `information_schema` database
cannot be queried due to the connection problem of some external catalog, so as
to solve the problem of using some BI tools with Doris. It can be controlled by
the FE configuration `infodb_support_ext_catalog`, and the default value is
`false`, that is, the meta information of external catalog will not be returned.
+
+## Improvements
+
+### JDBC Catalog
+
+- Supports connecting to Trino/Presto via JDBC Catalog
+
+ Refer to:
[https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#trino](https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#trino)
+

mapping
+
+ Refer to:
[https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#clickhouse](https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#clickhouse)
+
+### Spark Load
+
+- Spark Load supports Resource Manager HA related configuration
+
+ Refer to: https://github.com/apache/doris/pull/15000
+
+## Bug Fixes
+
+- Fixed several connectivity issues with Hive Catalog.
+
+- Fixed ClassNotFound issues with Hudi Catalog.
+
+- Optimize the connection pool of JDBC Catalog to avoid too many connections.
+
+- Fix the problem that OOM will occur when importing data from another Doris
cluster through JDBC Catalog.
+
+- Fixed serveral queries and imports planning issues.
+
+- Fixed several issues with Unique Key Merge-On-Write data model.
+
+- Fix several BDBJE issues and solve the problem of abnormal FE metadata in
some cases.
+
+- Fix the problem that the `CREATE VIEW` statement does not support Table
Valued Function.

+- Fixed several memory statistics issues.
+
+- Fixed several issues reading Parquet/ORC format.

+
+
+In version 1.2.5, the Doris team has fixed nearly 210 issues or performance
improvements since the release of version 1.2.4. At the same time, version
1.2.5 is also an iterative version of version 1.2.4, which has higher
stability. It is recommended that all users upgrade to this version.
+
+## Behavior Changed
+
+- The `start_be.sh` script will check that the maximum number of file handles
in the system must be greater than or equal to 65536, otherwise the startup
will fail.
+
+- The BE configuration item `enable_quick_compaction` is set to true by
default. The Quick Compaction is enabled by default. This feature is used to
optimize the problem of small files in the case of large batch import.
+
+- After modifying the dynamic partition attribute of the table, it will no
longer take effect immediately, but wait for the next task scheduling of the
dynamic partition table to avoid some deadlock problems.
+
+## Improvements
