+Many status page API endpoints have been removed; for all remaining endpoints, CORS
+(Cross-Origin Resource Sharing) has been disabled, as it led to a privacy issues:

+
+The removal of CORS breaks compatibility with the node switching feature of the
+old status page implementation: In the new status page, switching to another node will
+reload the whole status page from the target node, while the old implementation would
+only switch to another backend host. While this will facilitate future updates, as
+frontend and backend always come from the same node and no stable API needs to be maintained,
+it prevents switching from the old status page to nodes running the new version.

+To achieve all this, the status page was ported to the gluon-web framework. The new status page
 also makes use of Gluon's usual i18n facilities now. In addition, the gluon-web-model
 package was split out of the gluon-web core package, as model support is only required
 for config mode packages, but not for the new status page.
