I realized that creating pipeline button has changed. Databricks has brought new options to the create pipeline button. After selecting create etl option, the new json configuration is seen as the following:

{
    "development": true,
    "continuous": false,
    "channel": "CURRENT",
    "photon": true,
    "libraries": [
       ...
    ],
    "name": "Test pipe",
    "serverless": true,
    "catalog": "...",
    "schema": "dev",
    "data_sampling": false,
    "budget_policy_id": "..."
}

The diffs are those:

-  "photon": true,
- "data_sampling": false,
- "budget_policy_id": "..."

Is this relevant?
