+### Rank Estimation
+
+A new feature in v1.3 is the rank estimation panel. This adds an extra graph which uses a statistical model to estimate the playing strength
+of both players for every 80 move segment. It can be used for determining which part of your game needs extra attention,
+but keep in mind the estimation is based purely on how well moves correspond to the 'shape sense' of KataGo and can be very inaccurate at times.
