+## Bug Fixes
+
+[IOTDB-5604] NPE when execute Agg + align by device query without assigned
DataRegion
+[IOTDB-5619] group by tags query NPE
+[IOTDB-5644] Unexpected result when there are no select expressions after
analyzed in query
+[IOTDB-5657] Limit does not take effect in last query
+[IOTDB-5700] UDF query did not clean temp file after the query is finished

time desc
+[IOTDB-5722] Wrong default execution branch in PlanVisitor

is incorrect
+[IOTDB-5755] Fix the problem that 123w can not be used in Identifier
+[IOTDB-5756] NPE when where predicate is NotEqualExpression and one of
subExpression is not exist
+[IOTDB-5757] Not Supported Exception when use like ' s3 || false' in where
