Final bits are now available through the Open MQ project. Production bits are included with Oracle GlassFish Enterprise Server downloads. The changes applied post the RC for build 29 were for packaging only.
As I hope you know, MQ is no longer offered, stand-alone. You may use the community version, but it's only eligible for "community support." Production support is now included with GlassFish Enterprise Server license and support.
You can obtain the community version at http://mq.java.net/downloads.html.
