If you're talking about structual changes (field name changes, delete fields, etc), I don't think that's possible with Airtable natively
If you're talking about field data changes, you could technically create one automation per field? You'd max out at 50 automations though
If you're looking to get a single automation to handle this, it's also possible but super tedious to set up. You'd need a system that logged your current field data, compared it against the latest version, and displayed a report on which fields were changed
