Hi Marton, you are correct, the ChEMBLdb Connector references an older version of ChEMBLdb. It’s part of the community contributions, so it would be best to follow up with the developers directly about the update.
In the meantime, you can use the latest API of ChEMBL via GET Request interface. Here is a workflow from the EXAMPLES Server to help you get started
/EXAMPLES/50_Applications/30_RESTful_ChEMBL
and a blogpost describing it

Hope it helps.
Best,
Daria
