Applied Cryptography: Protocols, Algor. And Src Code in C (20th Anniv. Edition)

I already have the 1996 2nd Edition of this book and I love it.

Had to shorten the title to get it submitted.

Would anyone who has access to the new and old editions of the book recommend getting the new edition?

I went through the Amazon reviews and one reviewer feels that the content has not changed much.

I can't see a 'Look Inside' feature to go through the contents either.

If what the Amazon reviewer is saying is true, I wonder why Bruce Schneider went to the trouble to release a new edition without substantial content addition/revision.
