Description
Take two points layers (example attached) and create a distance matrix in QGIS 2.18.26 and 3.4.2.
Results are different, and both are false. With points in example, max distance should be approximately 8 meters (max result of 2.18 -> 2820557.60885 ; 3.4 -> 2803875.70748).
The layers and the project are in EPSG 2056 (unit = meter). Meters are defined as default unit in QGIS preferences.

[processing] Throw error when attempting to use Distance Matrix with
multipoint datasets
There's no single approach to use for multi-point inputs, so instead
of overloading this algorithm with extra options to control how these
are handled, we raise a helpful error and push the reponsibility back
to the user to get the data into the right format before running the
tool.
