WildFly 39.0.1 is released!

By Radoslav Husar | February 12, 2026

I am very happy to announce that WildFly 39.0.1.Final is now released and available for download (or to be provisioned by Galleon, fetched as Container images on Quay, or obtained by whichever distribution mechanism you prefer).

The complete WildFly 39.0.1.Final release notes are available on GitHub.

I want to highlight great work of our community users during this maintenance release. Rhuan H. found a memory leak issue and did absolutely amazing work analyzing, debugging and verifying the fix. Cody L. found and promptly reported an issue where max-post-size in Undertow was not being properly applied, capping uploads at 2 MB.

Give it a try, upgrade and give us your feedback, in the WildFly google group, Zulip or Jira.

Best regards,

Rado
