The nightly build has just been updated to v 1.15.0 which provides 4 new distance nodes (1-D, 2-D, 3-D and n-D Distance):
These nodes calculate the distance or squared distance between points with their coordinates stored in columns.
This update superceded a bug fix update, v 1.14.1 released briefly earlier today, which fixed a bug meaning that the Table Name selection was sometimes lost from the Select Database Table (Interactive) node on reload.
