I'd let these slip a bit - but I just updated the Project 2016, Project Server 2016 and Project Server 2019 posts with the updates through to December 2019. For the 2019 client - the updates can be found at https://docs.microsoft.com/en-us/officeupdates/monthly-channel-2019 or https://docs.microsoft.com/en-us/officeupdates/semi-annual-channel-2019 depending on the channel you get Office through (Monthly or Semi Annual - other channels are available)
