New Macro PAGE_URL | We have replaced our ‘referrer’ macros with ‘page’ macros. In case you did use ‘referrer’ macros in the past: Please replace these macros ${REFERRER_URL} / ${REFERRER_URL_ENC} with ${PAGE_URL} / ${PAGE_URL_ENC}. The new macros will from now on collect URLs of web pages where the impression showed up. The old macros have been deprecated.
