In late 2018 we rolled in a revision to our 125mm and 150mm TRS+ seatpost which incorporated feedback from the first generation production. The new posts can be identified by having a V15 in the production date code. The most obvious change for riders is that the number of stop positions were changed from 4 stops on V10-V14 posts to 3 stops on V15 posts. This means there is only a single stop between fully compressed and fully extended. The change helps with more easily finding the middle spot for undulating terrain and also improves the reliability.
