Vendors control their APIs. Most vendors publish a “Version Life Cycle” (here is Airflow’s) which gives you visibility into which release versions will be live and maintained, then sunsetted when, etc. The various systems and their APIs all are in a constant state of change. Our operations team monitors all these changes and as we move ahead in any one year, we plan and adapt as needed.
Some API change can be a surprise, and in those cases our developers can react quickly.
