question about lintian warnings

[Evgeniy Dolgih <marcondream@gmail.com>]

Hello.
I going to adopt of orphaned package. I'm doing like described in this
instruction: http://www.debian.org/devel/wnpp/index.en.html. I'm almost
done with packaging but  lintian shows me 2 warnings:
changelog-should-mention-nmu and
source-nmu-has-incorrect-version-number. I'm double check debian/control
and debian/copyright files for correct maintainer record and dont
understand why lintian show warnings.

Or this warning is normal for packages when changes maintainer of
package?
Thanks.
