• Support for the display of a custom message (title and body) in an empty mobile inbox.
  For more details, see Customizing Mobile Inbox on Android
• Support for syncing in-app message read state across multiple devices:
  • When the SDK fetches in-app messages from Iterable, it examines each message's read field to determine if it has already been read.
  • The SDK's default implementation no longer automatically displays in-app messages that have already been seen on another device (even if those messages were not configured to go directly to the inbox).
