Thanks, v8 uses that format.

v8 will be the core, the hookup into the stack recording path, the
statistics file, the documentation and the basic selftest, with your
comments on 01-03 addressed. The binary export will carry the generation
in its header, so I would like the core and the cookie format to settle
first; the binary export, its parser and the capacity boot parameter
will follow as a separate series. If you would rather have them in the
same series, I can include them.

So there is no need to look at 04-10 of v7.

Thanks,
Pengfei Li
