As noted, Facebook is changing their API substantially. We're knee-deep in a new release that should be out around the end of the month that incorporates most of these changes into it. Some features will be removed, others are changing. We have no control over it, unfortunately.
The permissions Facebook has required for specific features is changing and other features that have worked with less or no permissions now require more permissions from the user to approve of first. The posting of content to your Facebook Page is an area Facebook is changing a bit. It's still allowed, but they're elevating many of the permissions to require the approval process.
Please note though that the above message specifically says that it is only shown to developers or admins of your app. Normal users wouldn't see that scary red box. Normal users simply won't be asked for those permissions. The Channels feature is almost always setup by admins of your app though, so you can still approve those permissions *and* you don't have to go through the revview process with Facebook. The review process is only if plan to ask those permissions from normal users/guests, and most of the time, that isn't required for Page posting or other Channels features.
Other profile import permissions, like birthday, hometown, location and some others have always required the review process to be performed and will continue to do so if you want to get extended profile information from your users.
If you're experiencing something other than the above, please let us know what issue it is and we'll gladly investigate further.
Thanks,
Alex
