9.3.1

• Bug with DynamoDb Outbox and the Outbox Sweeper fixed. The Sweeper required a topic argument supplied by a dictionary of args
  • Required adding a Dictionary<string, object> to various interfaces, which defaults to null, hence the minor version bump as these interfaces have new capabiities
• Internal change to move outstanding message box to a semaphore slim over a mutex as thread-safe. Not strictly neededm, but follows our policy of moving to semaphore slim
• Changes to the DynamoDb Outbox implementation as Outstanding Message check was not behaving as expected
• The interfaces around Outbox configuration will likely change in v10 to avoid current split and need to configure on both publication and outbox
