Has this been tested with real scan data, I am not sure that ex raids will be shown to not invited players.

Also you need to fix travis and do a proper DB migration to add the new column

As people who can't participate in the raid get this message:

(from TSR: https://www.reddit.com/r/TheSilphRoad/comments/70d5sh/ex_raids_from_wave_2_now_display_gym_closure/)

There must be some way of detecting an EX raid.

But it looks like non-participants can't see the egg (the message above only appears once the raid actually starts), so how useful this will be is an open question.

exclusive raids are being "tested" so yes only invited players will be able to see it right now but when they go global im sure the "'exclusive': raid_info.is_exclusive" will still be used so i can see this possibly being useful some point... when they do activate globally tho im sure current setups will still post them as long as the assets are there and enabled, i added the basic mewtwo stuff a few weeks ago to my copy...
