The bug

The '/clone' command has been updated to properly check for overlapping source and destinations areas no longer allowing for a 1 block depth overlap on each axis. This can continue to be overridden via the force clone option

This change broke /clone move. It used to be possible to move a structure over by one block, but it is no longer possible.

How to reproduce

1. Build a 3x3 floor beneath you
2. /clone ~-1 ~-1 ~-1 ~1 ~-1 ~1 ~ ~-1 ~-1 replace move

Expected result

Floor should shift one block in the positive X direction

Actual result

Error: source and destination cannot overlap

This defeats the entire purpose of the move option. It is supposed to have the same overlap-bypassing behavior as force, which it is mutually exclusive with.
