Voting starts in March for the Drupal Association Board election.
Currently there is no way for content editors to place blocks on their pages that are targeted for specific audiences through the IPE.
eg, you have a members only block that you only want members of your site to be able to view. The only way to do this currently is to edit the panel through the full featured panels interface and create visibility rules to limit by role (or other criteria). Great for site builders, but impossible for content editors that only have access to the IPE.
