  - Added "201" http status to various entity creation responses.
  - Replaced the old search engine system with a brand new one, that is more
    powerful, easier to use, and more flexible.

+1.8 Output Chunking
+
+Starting in 6.9 WebGUI www_ asset methods are capable of having full control
+over the output buffer. They can use $session->output->print() to send chunks
+of content back to the browser before the page is entirely processed. The 
+advantage here is that the page appears to load more quickly to the end user.
+The disadvantage is that you must set up any HTTP and HTML headers before you
+start to send any content. The view() method now has a companion method called
+prepareView() in which HTML and HTTP headers must be set. See any of the
+existing assets and wobjects for implementation details.
