Thanks, I'll take a look.

In general make sure that you prefix new versions with "PATCH v2", "PATCH v3" etc
and include a changelog below the cutlist or in the cover letter.

There is a --subject-prefix argument for git send-email you can use.

It's okay this time, but if you end up spinning again for a v3 do that.
