Ad networks that serve javascript files won't work unless CSP is
disabled (a bad idea), or the content security policy script src
site setting is updated to include all sources of permitted
javascript. We will keep instructions up-to-date in the first post
of this topic: https://meta.discourse.org/t/33734
Each ad placement in the AdSense and Ad Manager settings takes a list
of ad sizes instead of only one size. If given multiple sizes, the sizes
will alternate in order for each ad that's rendered.
If you want to use one Ad Manager publisher on desktop and a different
one on mobile, use the new dfp_publisher_id_mobile setting.
By default, dfp_publisher_id will be used for both desktop and mobile.
Enter a list of tags in the new setting no_ads_for_tags to prevent
ads from being rendered on topics with one or more of those tags,
and on topic list pages for those tags.
Use the new "house ads frequency" site setting to configure how often
house ads should show, as a percentage. This only applies in ad
placements where other ad networks are configured to appear.
A new setting has been added in Admin > Settings > Ad Plugin called
"no ads for groups". Add group names to this list. If a user belongs
to any of the groups, they will not see any ads. This is an alternative
to using trust level settings like "adsense through trust level".
