Deprecation: CONDITION is now a single expression instead of list.

If you previously had a list it is recommended to use the CONDITIONS keyword instead. This will become a requirement in a future release.

Alternatively you could merge the conditions to a single expression. This is what is done automatically when using the CONDITIONS keyword.
```
     CONDITION: expression1 {*} expression2 
     CONDITION: 
       - expression1 
       - expression2 
```
