-
-## Behavior Changed
-
-1. Change float type output format to improve float type serialization
performance.
-
-- https://github.com/apache/doris/pull/32049
-
-2. Change system table value functions active_queries(), workload_groups() to
system tables.
-
-- https://github.com/apache/doris/pull/32314
-
-3. Disable show query/load profile stmt because there are not so many
developers use it and the pipeline and pipelinex engine not support it.
-
-- https://github.com/apache/doris/pull/32467
-
-4. Upgrade arrow flight version to 15.0.2 to fix some bugs, so that please use
ADBC 15.0.2 version to access Doris.
-
-- https://github.com/apache/doris/pull/32827.
-
-
-

Doris can still obtain the client's real IP and implement permission control
such as whitelisting.
-
-- https://github.com/apache/doris/pull/32338/files
-
-5. Add workload group queue related columns for active_queries system table.
Uses could use this system to monitor the workload queue usage.

+2. Some of MySQL Connector (eg, dotnet MySQL.Data) rely on variable's column
type to make connection.
+
+ eg, select @[@autocommit]([@autocommit](https://github.com/autocommit))
should with column type BIGINT, not BIT, otherwise it will throw error. So we
change column type of @[@autocommit](https://github.com/autocommit) to BIGINT.
