Please. I ducked v1 because a v2 was in the works. It's very late in the cycle so you might want to prepare an urgent-for-4.19 series and a for-4.20 series. Or, better, a single series with the appropriate Cc:stable tags. Please ensure that all review questions which have thus far been received are appropriately answered in code comments and in changelogs. Because if one reader was wondering about something, others will wonder the same thing in the future.
