+## Upgrading from Spark SQL 2.4.5 to 2.4.6

+ - In Spark 2.4.6, the `RESET` command does not reset the static SQL configuration values to the default. It only clears the runtime SQL configuration values.

+## Upgrading from Spark SQL 2.4.4 to 2.4.5
 
  - Starting from 2.4.5, SQL configurations are effective also when a Dataset is converted to an RDD and its
    plan is executed due to action on the derived RDD. The previous behavior can be restored setting
