Ack, took note. I will do on top v6.8 tag.

questions: when something go wrong in a pull request....

- Should I keep the old tag, and then do another one with -2
(it seems you do like this), or delete the old tag and send it again
with the same name?

- Should I resend the PULL request with something in the log or
at the Subject saying it is a v2 of the pull request?

I could ask via chat, but I think it is good for the community to
have access to these info.

Thanks!
