Every team can prepare an agile board so their members can pick up work from this board. Request and problems could already be placed on an agile board. Now tasks that are part of a change can also be placed on agile boards.
Because team members should see only the tasks that are assigned to their team, their agile board will never show any approval tasks. And because people should not work on registered or canceled tasks, those tasks will also not show up on an agile board.
Other than that, change tasks respect the configuration of each column of an agile board, just like requests and problems.
