There is no SoB tag in your message. Homework: to understand what went wrong
and fix in v6. Without SoB tag this may not be considered at all.

Also, if somebody gave you a tag (reviewers/maintainers) in the previous
versions, it's your as a contributor responsibility to bear those tags with
new versions in case there were no drastic functional changes. Otherwise
there is no point to review your changes.
