Room 2.6.0-alpha03

Nested Map return types in DAO functions are now supported in Room. ( I13f48, 203008711) A new type annotation called @MapColumn has been created to replace @MapInfo, which is now deprecated. For each column name ( keyColumnName, valueColumnName, or both) provided in a @MapInfo annotation, you will need to declare a @MapColumn annotation with just the columnName and use the annotation on the specific type argument that is being referenced (the key or value of the Map) in the return type of the DAO function. This is because the @MapColumn annotation is used directly on the type argument within the return type of a DAO function, instead of on the function itself like @MapInfo. For more information, please refer to the @MapColumn documentation. ( Ib0305, b/203008711) Updated API files to annotate compatibility suppression ( I8e87a, b/287516207) The Room Gradle plugin APIs have been updated to not always require per-variant configurations. This means that the plugin can accept a global location for all variants without creating multiple directories, enabling smoother migrations that but is also flexible enough to manually configure flavors or build type schemas while still retaining the benefits of the plugin (reproducible and cacheable builds). ( I09d6f, b/278266663) Fixed potential memory leak vulnerability in QueryInterceptorStatement. ( I193d1) Fixed incorrect behavior in the QueryInterceptorDatabase execSQL() function. ( Iefdc8)
