We had a day on Glencoe about a month ago now.
The black was in a poor state of repair and whilst not specifically closed, they’d tried hard to discourage you from riding it by placing a makeshift barrier where it leaves the red.
As a result, the red was getting a LOT of use and it was suffering a bit.
I haven’t ridden there previously, so can’t say if anything was “new” but it all looks well bedded in.
TBH, it’s just a lumpy rocky blast, with very little in the way of features. We sacked it off after a few hours and rode the Devil’s Staircase over to Kinlochleven instead.
Rode Fort William WC track the next day and thought that was 1000 times better.
