Take a look at package examples, with non-release version:
https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/emacs.scm?h=#n560

The revision starts at 0 and get increased every time commit value is
updated.  It resets to 0, when the version changes.

Please, adjust to this style and send the whole series as v2.
