I updated our v8 instance to v803 a few minutes ago. Downloaded the install binary from https://licensing.tableausoftware.com/esdalt/. Since the install binary name does not provide the version number, wanted to confirm I installed v803 by looking for the version number on a log file or other means. Looking at documentation found the following and ran them but neither of them returns references to 8.0.3.
I ran: >tabcmd version ===== Tableau Server Command Line Utility -- Version 8000.13.0712.1936
