OpenAjax Hub 2.0 has been finalized by the Interoperability Working Group and formally approved by the members of OpenAjax Alliance and the Steering Committee. OpenAjax Hub 2.0 therefore is now an approved Ajax industry standard. The big new feature in Hub 2.0 (versus Hub 1.0) is its Managed Hub feature which isolates third party widgets (potentially malicious) into secure sandboxes and mediates messaging among the widgets with a security manager. Hub 2.0 consists of a formal Specification and a commercial-ready open source implementation. A more complete announcement is coming soon.
