Today we have released the 27.0.0.Alpha4 version of WildFly, now available on the downloads page. This release serves as a major milestone on our way toward support for Jakarta EE 10 in WildFly, as it is the first release of standard WildFly that is based on the Jakarta EE APIs that are planned for the upcoming Jakarta EE 10 release. Until this release, only WildFly Preview has offered any kind of support for Jakarta EE beyond EE 8.

As discussed in my January WildFly Release Plans for 2022 post, the main focus of the WildFly developers as we work on WildFly 27 is implementing Jakarta EE 10 support. That work has now reached a point where it’s useful for our community to have an early look at our planned EE 10 implementation.

We’ve also done a WildFly Preview 27.0.0.Alpha4 release. The differences between standard WildFly and WildFly Preview are currently rather minimal, as the EE 9+ support that’s been WildFly Preview’s biggest calling card has now been brought into standard WildFly. A major difference between WildFly Preview and standard WildFly is Preview retains the feature that will bytecode transform deployments that use the EE 8 javax.* APIs so that they instead use the analogous jakarta.* APIs. We do not intend to include that feature in standard WildFly, but we’re retaining it in WildFly Preview, at least for now. (See 'WildFly Preview Support for EE 8 Deployments' in the 2020 Jakarta EE 9 with WildFly Preview announcement for more on this feature.)

Note that we have not added a 'Servlet-Only Distribution' variant of WildFly to the downloads page. The WildFly project is no longer producing that distribution. I encourage users looking for the kind of slimmer server installation formerly provided by the 'Servlet-Only Distribution' to use Galleon to produce a server installation tailored to your needs.

We’re also not releasing quickstarts or cloud images for this release.
