# Removal of regression-v2 scoring algorithm

A new version of the API will remove the `regression-v2` scoring algorithm, but leave `regression-v1` in place for now. `regression-v2` is a historic scoring method that is discouraged for screening use (it's intended use is internal de-duplication of entities in our database).

A new `regression-v3` scoring mechanism is now being developed and will be released, but not recommended for screening use. Any requests that are sent to the API using `regression-v2` will be re-written to use `regression-v3` in the future.
