Hi Stefano,

Most of the changes in 3.0 are described at
https://open-babel.readthedocs.io/en/latest/UseTheLibrary/migration.html#molecule-atom-and-bond-flags.
In short, OBMol::SetPartialChargesPerceived(false). The rationale for this
change is described at https://github.com/openbabel/openbabel/pull/1951.

Regards,
Noel
