 - JavaScript can not be involved with the initiation of font loading.
 - Font loading gets controlled (but not initiated) by [`<amp-font>`](https://github.com/ampproject/amphtml/issues/648).
 - AMP by default does not allow inclusion of external stylesheets, but it is happy to whitelist URL prefixes of font providers for font inclusion via link tags. These link tags and their fonts must be served via HTTPS.
-- If a font provider does referrer based "security" it needs to whitelist the AMP proxy origins before being included in the link tag whitelist.
+- If a font provider does referrer based "security" it needs to whitelist the AMP proxy origins before being included in the link tag whitelist. AMP proxy sends the appropriate referrer header such as "https://cdn.ampproject.org".

+## AMP Dev Channel (Experimental)
+
+AMP Dev Channel is a way to opt a browser into using a newer version of the AMP JS libraries.
+
+This release may be less stable and it may contain features not available to all users. Opt into this option if you'd like to help test new versions of AMP, report bugs or build documents that require a new feature that is not yet available to everyone.
+
+To opt your browser into the AMP Dev Channel, go to [the AMP experiments page](https://cdn.ampproject.org/experiments.html) and activate the "AMP Dev Channel" experiment.

@@ -34,6 +34,7 @@ We will provide the following information to the ad:
   In browsers that support `location.ancestorOrigins` you can trust that the `origin` of the
   location is actually correct (So rogue pages cannot claim they represent an origin they do not actually represent).
 - `window.context.canonicalUrl` contains the canonical URL of the primary document as defined by its `link rel=canonical` tag.
+- `window.context.pageViewId` contains a relatively low entropy id that is the same for all ads shown on a page.
 - [ad viewability](#ad-viewability)
 - `window.context.noContentAvailable` is a function that the ad system can call if the ad slot was not filled. The container page will then react by showing placeholder content (not by collapsing the ad slot; sizing rules apply).
