Derail Valley last posted a patch note 3 months ago (Jul 20, 2026: B100 Progress Update 1).
Derail Valley averaged 0.1 updates a month over the last year. Derail Valley is rarely updated (6/100). 1 of the last 12 months had at least one update day. Not enough of a cadence to call it regular.
Not yet. Derail Valley is slowing down: the last signal is between 90 and 180 days old.
