Checking for Incompatibilities between Version 21.0.4 and 21.0.5

As a system administrator, you need to check incompatibilities between consecutive versions before upgrading your system.

The tables below list new features that might lead to compatibility issues or should be taken care of when upgrading; they do not list all new features of this AE version. New features are described in full in the Release Highlights and Release Notes.

More information:

To provide a better overview, the tables are categorized by the severity of the issue. There are three different categories:

Critical: Issues that must be addressed, otherwise the system will not work
Behavior change: Functionality changes in existing features that might have an impact on your system
Advisory: Different issues you should be aware of but might not have an impact on your system

The columns display the following information:

Topic: Name of the general topic or new feature
Changed behavior: What has been changed
Possible incompatibilities: Impact the change may have
Actions/Countermeasures: What can be done to identify and/or remove possible incompatibilities

This page includes the following:
