+
+description: |
+  6-axis MotionTracking device that combines a 3-axis gyroscope and a 3-axis
+  accelerometer.
+
+  It has a configurable host interface that supports I3C, I2C and SPI serial
+  communication, features up to 8kB FIFO and 2 programmable interrupts with
+  ultra-low-power wake-on-motion support to minimize system power consumption.
+
+  Other industry-leading features include InvenSense on-chip APEX Motion
+  Processing engine for gesture recognition, activity classification, and
+  pedometer, along with programmable digital filters, and an embedded
+  temperature sensor.

I don't see any improvements (nor explanations in the changelog)

Best regards,
