New features include:
- Message list searching: The message list can be filtered based on the subject/to/from text.
- Error simulation: The server can now simulate common error that can occur during message sending. This allows developers to test how their code will react.
- Messages now saved to a folder: The messages are now saved to files instead of being kept in memory. This means that the application should cope with more and larger messages. The folder is configurable from the options dialog.
- Better session error handling: Unexpected exceptions in a connection thread no longer crash the application. A notification is shown to the user and the exception details shown in the session log.
