The patch also is adding more solo randomized dungeons in the blue and yellow zones of the game, making them disappear a short time after the last player enters and having a new dungeon entrance spawn somewhere in the world shortly after. This change is meant to give newer players greater access to the full dungeon experience while still allowing players to run solo dungeons together and follow others into a dungeon within what’s called a “reasonable” time window.
