Kevin,

Unfortunately, I have chosen to drop the series. We are too late in
the window to take the updated series and wait for new regression
reports. On the flip side, this will clean up the flow for Ulf to take
your V5 since the dependent series should ideally hit rc1 by then.

Thanks for addressing the report fast.
