Q4M version 0.3 released

Today I have released Q4M version 0.3. Changes from the previous are as follows.

Support for message relaying

Messages submitted to Q4M tables can be forwarded to another Q4M table on a different MySQL server. The transfer is trustable, 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.

Prioritized subscription to multiple tables

Clients can now subscribe to more than one table at once. The subscription priority can be specified, thus it is able to create a priority queue using multiple tables.

For more information, please refer to the Q4M homepage.
