Wherever possible, do explicit data conversion, for example using a "Select Values" step (using the metadata tab) or using the "JavaScript" step.
Add Sequence

At design time, it returned data type "Integer(9)" for the sequences.
...
To stay compatible with the old run-time behavior, we decided to remove the length (9) from the design-time metadata.
As such you will see a difference when designing transformations. (not when running it)
Stream Lookup
This step has to be verified in case the data types of the lookup data does not correspond to the data type of the input data. (see Implicit data conversion)
