v23.07.00 > Upgrade to Ubuntu 22.04 / PHP8

Release v23.07.00 includes software updates to run on Ubuntu 22.04 and PHP8.

  1. Unfortunately, these updates WILL NOT run on a default Ubuntu 20.04 / PHP 7.4 system, so it is required that you update your primary server’s operating system, and the operating system of any autograding worker machines before installing Submitty v23.07.00.

  2. The list of disabled PHP functions must also be updated to remove chmod. chmod must now be allowed. See also System Customization - Disable PHP Functions
