This release changes the cluster data format! The mean column / row are not centered anymore.
Consider a cluster with on pixel at column / row = 1 / 2
Before:
cluster: mean column / mean row = 1.5 / 2.5
Now:
cluster: mean column / mean row = 1.0 / 2.0
This adresses issue 2 and solves the discrepancy that cluster seeds were not shiftet by 0.5.
