Every quarter we release a new version of the Datamodel, this new version contains major changes to the model, mandatory changes that require you to evaluate and often update your connection.
In addition to the quarterly release we now also release weekly updates of the model. These weekly updates contain minor updates that are optional for you to implement.
By offering these weekly updates you are now able to use new classifications and attributes quickly after they are released, without having to wait for them to appear in the quarterly update. The weekly update is available at https://developers.bol.com/datamodel/
