Yes, all checkpoints are forward compatible.

However, you do need to restart the query if you want to update the code of
the query. This downtime can be in less than a second (if you just restart
the query without stopping the application/Spark driver) or 10s of seconds
(if you have to stop the application and resubmit your application to the
cluster).
