Update bolt protocol version (and manage object types)

[RubixR4]

The driver seems to handle bolt protocol v1 only. I try to update/return object types as parameters (ex : Point) and the server returns this message "Point is not supported as a return type in Bolt protocol version 1. Please make sure driver supports at least protocol version 2. Driver upgrade is most likely required."

As I do not see any new commit for 2 years, I wonder if the driver is still maintained, but I absolutely need to find a solution to manage those types because some of my queries are based on distance calculations and I have a index on a point property. Also, I would like to keep the benefits of parameters and avoid harcoding the point directly in the query.

Does anyone know if I can use any workaround of if an update is sheduled for the driver ?
