Yes, that's correct.
Due to the substantial changes from the original version, I don't think
our patch counts as being finished before November 1st. We're continuing
to work on it, but I think that the earliest we'll be ready for review
is at the end of the week.
We don't want to hold anything up, so feel free to move on to another
patch. If you still have time to review when we have a better patch,
we'd appreciate your feedback even if it's too late for 8.4.
Regards,
Jeff Davis
