WildFly 22 is released!
by Brian Stansberry
Hello everyone,
It's a new year so it's time for a new WildFly! I'm pleased to announce
that WildFly 22.0.0.Final is now available for download at
https://wildfly.org/downloads/. Please try it out and give us your feedback.
This release includes support for use of log4j2 in applications, new base
health and metrics subsystems to provide server observability for users who
don't need the application instrumentation that comes with MicroProfile
Health and Metrics, and a number of other features related to management,
provisioning, messaging and security. Plus numerous bug fixes, enhancements
and component upgrades.
We've also released an updated version of the new tech-preview WildFly
Preview distribution that we're providing to let our community have a look
at what we're doing for Jakarta EE 9 support, along with other changes in
the server architecture that we're expecting to appear in the main WildFly
later in 2021.
Learn more in my post at
https://www.wildfly.org/news/2021/01/13/WildFly22-Final-Released/
<https://www.wildfly.org/news/2020/01/13/WildFly22-Final-Released/>.
Folks are already busily at work on WildFly 23!
Thank you for your support of WildFly.
Best regards,
Brian
