Hi @wordpressdublin,
it’s not an ad panel, but a notification with a summary of the latest improvements, plus a form to subscribe to the Yoast newsletter (which is completely optional and free).
The notification can be dismissed with a simple click and won’t be shown again until the next update.
Actually, in the new version released just today the notitication is displayed only in websites who are upgrading from versions before 3.2.5, because it’s important for the users to know that the plugin has changed name and ownership. Also, the notification is now displayed (until dismissed) just in a couple of screens instead of everywhere, as it was before.
I hope these improvements will be welcomed, and you may give Duplicate Post another chance.
Thank you for your feedback!
