Along with other Middleware technologies, the latest SOA 11g version (184.108.40.206) — something we have simply been calling PatchSet 3 or PS3 — has been released and is now available for download from the Oracle website.
You can expect to download two zip files totaling around 2.6GB total.
The formatting for the downloads pages seem to be getting better as the features are now included along with links to the technologies as well. Oracle has also published a quick overview of new features in 220.127.116.11 (PS3). Enjoy your Oracle SOA 11g!
