We are now feature complete and (hopefully) bug fix complete for the SwitchYard 0.6 release. The big difference between Beta1 and Beta2 is the introduction of clustering. Transaction policy also got even more powerful as you can now specify transaction policy for service references (e.g. suspend a transaction when a service is invoked from your transactional service). There were 50 issues resolved between Beta1 and Beta2, so plenty of bug fixing and minor enhancements in there as well. Check out the Release Overview page for more detail.
No further work is planned for 0.6 pending feedback and issue reporting from the community. If no issues surface, 0.6.0.Final will be out in 7-10 days.
