90000.48 will be the final version of BonusRollPreview, as Blizzard is disbanding the bonus roll feature in Shadowlands:

I will push one last version just to update it to Shadowlands, since I already did most of the work. It'll then still work for older content, but I don't see much point in keeping it alive any longer, as the loot from old content is not something players will farm coins for.
