Great news – the cumulative updates for SharePoint Server, Project Professional and Project Server are all released and available for download.
—remember, if you are using Project Online and/or the “click-to-run” edition of the Project Client, you dont need to do anything as the updating happens automatically—
There is a lot information to cover and for that reason I Refer to the official Microsoft documentation found at the links below:
