No.  The "standard format" is the x86 book.bin, which is what everyone has
always downloaded from my web site.  If you are running on anything other than a
32 bit X86 architecture, you had to build a book.bin for that architecture.  You
now need to either download the "standard format" or else build a new one, which
will be in standard format automatically.
