Pleased to announce a new version of Diamond - v2.9.1

This release comes with the following:

* SEO Functionality, full support for schema.org (With the most 
common data structures already implemented.)

* placeHolder's deprecation period is over and all places using 
"placeHolder" must now use "placeholder".

* Fixes a critical bug that caused applications to crash with 
double slashes in the url.

* Better error messages for views.
