During job execution, variable values can be modified. However, by default, variable values never survive the end of job execution, resetting the value to as it was before job has been executed. This ensures that jobs will not interfere with itself down the line and makes executions predicable.
Since version 1.1.0, you can now specify if you want variable values persist between job executions.
Variables evaluated with formulas cannot be persistent.
