UPD

It was mentioned by @rubenfiszel in #389 that there was another subtle breaking change introduced in v0.37.0 release:

It is now an error to give positional parameters to a named query — previously only the DriverError::NamedParametersForPositionalQuery error was emitted and positional-for-named case wasn't covered at all (by the deprecated Params::into_positional function).

In v0.37.0 new DriverError::Params variant was introduced and the positional-for-named case is covered by the new Params::into_values function.
