When new versions of MailStream Plus are installed, does it automatically update existing parameter files and job scripts?

Product affected: MailStream Plus™, all versions, all platforms
With one exception (see below), when a new version of MailStream Plus™ (MSP) is installed, it does not update your parameter files for any changes, nor does it update the job scripts.  Users are required to make those changes themselves as needed. Needed parameter changes, and JCL/Script changes for each platform, are included in each release's 'Release Notes' document for that version.

The one exception is on the IBMi (iSeries/AS400/OS400) platform.  On that platform some of the changes are made when needed *and* when possible.   Please see Release Notes for new version.
For example- This was in the 8.3.3 Release Notes-
Your MailStream Plus™ Release 8.3.2 jobs will automatically forward to the Release 8.3.3 format. The forwarding program will delete old/obsolete parameters and parameter sub keywords. The forwarding program does not add new parameters and subkeywords, since some may be optional. Please be sure to update your jobs accordingly after forwarding.
