Bind 9 for Windows

Forgive me for interjecting a question here.  I just called Barnes &
Noble to inquire about the "DNS and BIND" 4th edition book.  They told
me over the phone they had the 5th edition.  Does anyone know anything
about what the difference between the 4th edition and 5th edition would
be?  I am currently running BIND DNS version 9.2.4.  Would the 5th
edition cover this version of BIND?

Thanks in advance for any information.
