In the CA PPM 15.5.1 Release Notes we see the supported Application Server version Tomcat 8.5.33 or higher. However when we download the Install Media for CA PPM 15.5.1 it includes version Tomcat 8.5.31. Which Application Server version is supported?
You can use Tomcat 8.5.31 on the Install Media ISO or Tomcat 8.5.33 version. Both will still be support-compliant.
