What's New in Grail Index
1.0.1
September 23, 2026
Portfolio value history now has 1D / 7D / 1M / 3M / ALL. ALL lets you drag a window to zoom the chart. The history chart spaces points by time and shows the hour when you’re looking at a short range. Active listings include live eBay offers next to SNKRDUNK, with prices rounded the same way as the website.
