Many of these new features have been the default for new deployments for several releases. + +The following features are deprecated, and we plan to remove support as early as Druid 36.0.0: + +* **Multi-value dimensions**: Druid now offers support for [array types](../querying/sql-data-types.md#arrays). +* **Non-SQL compliant null handling**: By default, Druid now differentiates between an empty string and a record with no data as well as between an empty numerical record and `0`. For more information, see [NULL values](../querying/sql-data-types.md#null-values). For a tutorial on the SQL-compliant logic, see the [Null handling tutorial](../tutorials/tutorial-sql-null.md). +* **Non-strict Boolean handling**: Druid now strictly uses `1` (true) or `0` (false). Previously, true and false could be represented either as `true` and `false` as well as `1` and `0`, respectively. In addition, Druid now returns a null value for Boolean comparisons like `True && NULL`. [Boolean logic](../querying/sql-data-types.md#boolean-logic).
