                  Release Notes: Support for message relaying and prioritized subscription have been introduced. By using a forwarder script, messages submitted to Q4M tables can be forwarded to another Q4M table on a different MySQL server. The transfer can be trusted, so there would be no message loss or duplications even on a server or a network failure. It is also possible to build a message broker above the API used for relaying. Also, clients can now subscribe to more than one table at once. The subscription priority can be specified, so one can create a priority queue using multiple tables.
