Thank you, Jungteak and Anton. To be clear, the Apache Spark committers can do normal backporting activities (bug fix patches) on branch-4.1 like the other release branches, `branch-4.0`. The Apache Spark PMC members can do backporting new features additionally until the mid of November. So, if you have any late-arrival feature patches, please ask your shepherd to backport for you.

I'm going to send another email about this topic for better visibility. Thanks, Dongjoon.
