There seem to be a number of new pathways that didnt exist last time I looked, I wandered into the Barrowdowns today, not using any of the entrances I knew; then later wandered from Chetwood to Archet and back, then up towards where those rather high level mobs are located, on the LoneLand border. Another place where the unclimbable cliffs have vanished and a gentle slope has appeared.
