It seems that, there is a hole with this deprecation. This feature has been deprecated but no other Annotation has replaced that functionality.
For now it seems that you can only add description programmatically
@Bean 
public Docket commonDocketConfig() { 
 return new Docket(DocumentationType.SWAGGER_2) .select() 
       .apis(RequestHandlerSelectors.basePackage("com.company")) 
       .paths(PathSelectors.any()) 
       .build() .apiInfo(apiEndPointsInfo()) 
       .tags(new Tag("Change timezone", "your description")); 
 }
Issue can be tracked here
@Api description deprecated without any alternative
You can try also with
@Api(tags = {"Change timezone"})
@SwaggerDefinition(tags = {
        @Tag(name = "Change timezone", description = "your Description")
})
public class YourController {
}
This annotation however already has an open bug for not behaving correctly @SwaggerDefinition bug
