Since the 5 season is based on the bookA Dance with Dragons: A Song of Ice and Fire, I'd say that there has been a major spoiler out since Jul 12, 2011, when the book was published.

Actually, I think the word for Season 5 is that it contains major deviations from the books. Martin is too slow, and the TV people are running out of story. His next book is out “who knows when”. So, now the novels and the series are somewhat separate affairs.

Not really. There are plot divergences already, some kinda big.
