Oracle SOA Suite 11g R1 Patchset 1 (aka 220.127.116.11.0) has been released
By clemens.utschig on Nov 10, 2009
You can get it at http://www.oracle.com/technology/software/products/middleware/index.html
Amongst many bug-, and performance-related fixes - we also added quite a few significant preview features (e.g resequencing, spring support, and others).
Please note that the role of preview features is to elicit user feedback on product directions. Preview features cannot be used in production and Oracle will not provide any support for them. In addition there is no commitment that a preview feature will ever get productized and supported in a later release.
However we will do our best to help via OTN SOA forums when people run into issues with those.
