It’s been a month since the WildFly 21 release, so we’ve done a small bug fix update, WildFly 21.0.1. It's available for download at https://wildfly.org/downloads/.

The full list of issues resolved in WildFly 21.0.1 is available at [1]. Issues resolved in the WildFly Core update included with WildFly 21.0.1 are available at [2].

Enjoy, and stay safe!

Best regards,
