Tommi_Nyman Most speculations are correct, slow adoption is the goal. But at the same time some updates do require the old panel to be removed before they can be implemented which is why we'd also like to speed up the process of moving everyone over to the new panel. An update to the old panel will be released soon, full of links to the new panel and update notices, some features will be disabled enforcing use of the new panel and so on.
Opinions on this would be appreciated, feel free to leave them here or contact support with your feedback. Both panels are currently up and running and in sync, but we don't know which one is most used or even most popular due to lack of monitoring. That's why feedback is very important.
