+##### Using Marcos in Row Level Filters
+  - Macros are now supported for using user/group/tag in row-filter condition expression, introduced in [Ranger 2.3](https://cwiki.apache.org/confluence/display/RANGER/Apache+Ranger+2.3.0+-+Release+Notes). This feature helps significantly simplify the row-filter condition expression by replacing explicit condition query by using user/group/tag's attributes. Consider user `bowenliang123` with an attribute `born_city` of value `Guangzhou `, the row filter condition as `city='${{USER.born_city}}'` will be transformed to `city='Guangzhou'` in execution plan. More supported marcros and usage refer to [RANGER-3605](https://issues.apache.org/jira/browse/RANGER-3605) and [RANGER-3550](https://issues.apache.org/jira/browse/RANGER-3550).
