Then select Preview?  Some customers have had problems with the distib pages because their site restricts access to some JS code we get from a third party.

Hi Yuriy -

Thanks for pointing this out.   We did not prepare a list for this, but I did make a comment on this thread, including verifying that none of these changes impacts any published API.  If there is a change resolving an issue you reported through the WRC, you'll see that this is resolved via the normal process.   We will be publishing detailed changenotes with the GA release.
