There is a new version of the OS X beta with a complete implementation for XEP-0352: Client State Indication and an initial implementation of XEP-0313: Message Archive Management . I know some issues with MAM that I will fix, in particular:
- last message received is duplicated
- time stamps on delayed messages are not the originals but when they arrived
- only retrieves the default number of messages from the server/ doesn’t handle paging yet.
If you see anything else, let me know.
