 * Removed fastjson library dependency for Beam SQL. Table property is changed to be based on jackson ObjectNode (Java) ([#24154](https://github.com/apache/beam/issues/24154)).
 * Removed TensorFlow from Beam Python container images [PR](https://github.com/apache/beam/pull/28424). If you have been negatively affected by this change, please comment on [#20605](https://github.com/apache/beam/issues/20605).
 * Removed the parameter `t reflect.Type` from `parquetio.Write`. The element type is derived from the input PCollection (Go) ([#28490](https://github.com/apache/beam/issues/28490))
+* Refactor BeamSqlSeekableTable.setUp adding a parameter joinSubsetType. [#28283](https://github.com/apache/beam/issues/28283)
