Wrong documentation
What article/section is this about?
docs.umbraco.com/umbraco-cms/reference/notifications/contentservice-notifications
Describe the issue
The description documentation for some of the notification events refers to using the raiseEvents parameter if you need to suppress a specific notification. The Content Service not longer appears to have this parameter, for example doing something like _contentService.Save(contentNode), doesn't have a raiseEvents parameter.
I'm not actually sure how you are meant to do this any more so can't update this documentation myself.
