New concept of CPI values from February 2023

From the next CPI inflation report for January 2023, which is published on February 14, and for all other CPI reports thereafter, the concept of inflation calculation will change. Since I don't understand myself, can someone interpret what this would mean and should it show a higher or lower CPI values in comparison to the previous model of CPI ?
