 ## 1.x.0
+
+Zoom Pan Pinch Wheel Activation
+-------------------------------
+This adds the ability to require an activation key such as 'Alt' to be pressed in order to enter
+panel zoom. There's a clash of interest between panel zoom and dashboard scroll which can be
+avoided by using this feature. Mew config terms in siteConfig and panelConfig:
+- zoomPanPinch
+
 Compound Colors
 ---------------
 This feature allows a labelColor, strokeColor or fillColor to be driven based off
