We need to fix our code in ods-ci to remove deprecated features in Robot Framework 5, which still exist but they might be removed in future versions:

Deprecated features affecting ods-ci:

• Run Keyword Unless  has been deprecated
• [Return]   is replaced by  RETURN
• In framework 5 release notes there is a list of deprecated items

We can use Robocop & Robotidy 2.x to check and fix some of the issues
