There is a very nice article about black holes and information being released. The article is very technical i would suggest seeking a news article.

I only scanned, but it looks interesting.
I deeply dislike the use of 'order and disorder' in the title. The latter appears only once in the paper other than the title, and it's clear that it's referring to entropy, not disorder. As for the former, of the 73 instances of 'order' in the paper, every single one except the one in the title is a reference to a hierarchy or is simply a vernacular use of order in sentences such as 'in order to...'. The instance in the title, juxtaposed with the term that they're using to refer to entropy, suggests that they're talking about entropy there as well.
The paper looks interesting, and I'll read it properly when I have leisure, but this is really shoddy writing from a scientific perspective, because entropy is not disorder. Disorder is a result of certain manifestations of entropy, and they don't apply to black holes, because black holes are the most highly ordered entities in the universe, while simultaneously being the most highly entropic.
Entropy is about placement on an energy gradient, with usable energy above you on the gradient (low entropy) and unusable energy below you (high entropy). In some circumstances, disorder is an indication of high entropy, but it isn't what entropy is. All else aside, which is the more ordered, a drop of water or a snowflake? Which has the higher entropy?
Lest we forget, gravity is an ordering force that increases entropy.
