I would be leary of putting 2019 SP4 out when it becomes available. There's a nasty bug that causes a real problem when trying to pick anything on the drawing. There's a setting that should prevent picking the hidden lines in a drawing view on a rendered view or view with the hidden lines removed. This setting does not work & causes a real time consuming effort to make sure you're picking the correct thing. This is the SPR for it if anyone is having that issue
