My app now has reached 5 ratings and is shown in the AppStore list with 5 stars now.
I sent an update to Apple which I marked "Hold for developer release".
Now:
(a) If I released the update, what would happen to my ratings? Are the people who rated for Version 1.0 allowed to rate again for Version 1.0.1?
(b) If (a) is true, are they allowed just to "rate" or to "rate and write a review" again?
(c) If nobody rates again, are the 5 stars still be shown?
(d) If (c) is true, no ratings are displayed in the AppStore list?
(a) People are allowed to rate again (in the fact, you can always rate again app, but only last rate is stored)
(b) They are allowed to rate and write a review
(c) Your rating will split to two ratings "current version" and "all versions", older, not updated, ratings will be available in "all versions" section.
-- updated
(d) When application has less than 5 ratings for current version, on app page is shown only average rating for "all versions"
