I've got a custom ContentSavingNotification handler, where I'm trying to determine if the blocklist content has changed. I'm really struggling to get the BlockList content into a strongly named model. I can get the BlockList json by doing this: var supportedFirmwareVersions = node.GetValue("supportedFirmwareVersion").ToString(); but doing this, just returns null: var supportedFirmwareVersions = node.GetValue("supportedFirmwareVersions"); once I've got the edited blocklist content, what would be the best way to find out what has changed? Do I need to get the node via the contentservice and compare?
