What is FusionAuth?

FusionAuth's feed publishes version numbers; whether they carry news is a coin flip.

FusionAuth releases every four to eight weeks, but the changelog entries are inconsistent: three of the last six carry nothing but an upgrade-guide link, while the ones that do have notes describe substantial standards and security work. The last documented release, 1.67.0, added RFC 8707 resource scoping so tokens issued by OAuth endpoints can be bound to specific resources. Before it, two consecutive releases tightened API key requirements — 1.65.0 for installation-wide endpoints, 1.66.0 extending the same rule to webhooks it had missed.

What is WildFly?

WildFly's quarterly train is really a stability ladder, and OIDC keeps climbing it

WildFly is four majors into a metronomic release train — 38 through 41 in about eight months — where each cycle pairs a Beta with a Final roughly two weeks later that restates the same feature list. The substantive work splits cleanly in two: Jakarta EE 11 and MicroProfile spec implementations that land first in WildFly Preview, and an explicit stability ladder (preview to community to default) that individual features climb one release at a time. OIDC is the feature getting the most of that attention, with scope attributes, request/request_uri parameters, and logout each promoted across the last three cycles.

FusionAuth vs WildFly: editorial side-by-side

F2.5

FusionAuth's feed publishes version numbers; whether they carry news is a coin flip.

◆ Current state

FusionAuth releases every four to eight weeks, but the changelog entries are inconsistent: three of the last six carry nothing but an upgrade-guide link, while the ones that do have notes describe substantial standards and security work. The last documented release, 1.67.0, added RFC 8707 resource scoping so tokens issued by OAuth endpoints can be bound to specific resources. Before it, two consecutive releases tightened API key requirements — 1.65.0 for installation-wide endpoints, 1.66.0 extending the same rule to webhooks it had missed.

◆ Where it's heading

Where the notes are readable, the direction is standards conformance and closing security defaults that were too permissive, accepting breaking changes to do it. FusionAuth has been willing to make an enabled identity provider's linking strategy immutable and to require global API keys where tenant keys used to work — changes that break running deployments in exchange for a tighter default. What cannot be read from this feed is where the last two releases fit, because they shipped without notes.

◆ Prediction

The pattern of hardening endpoint-by-endpoint suggests further scope narrowing wherever tenant-level keys still reach installation-level effects. Any read on 1.68.0 and 1.69.0 would be guesswork — the entries carry no content.

WildFly's quarterly train is really a stability ladder, and OIDC keeps climbing it

◆ Current state

WildFly is four majors into a metronomic release train — 38 through 41 in about eight months — where each cycle pairs a Beta with a Final roughly two weeks later that restates the same feature list. The substantive work splits cleanly in two: Jakarta EE 11 and MicroProfile spec implementations that land first in WildFly Preview, and an explicit stability ladder (preview to community to default) that individual features climb one release at a time. OIDC is the feature getting the most of that attention, with scope attributes, request/request_uri parameters, and logout each promoted across the last three cycles.

◆ Where it's heading

The direction is consolidation rather than expansion: features already written are being graduated to supported status instead of new subsystems appearing. In parallel the runtime baseline is moving underneath users — 40.0.1 shipped container images for JDK 25 on UBI 10 and flagged it as the last release carrying JDK 17 images. Expect the EE 11 work now sitting in Preview to graduate into standard WildFly on the same ladder OIDC has been walking.

◆ Prediction

WildFly 42 should ship container images on JDK 21 and JDK 25 only, with the remaining Preview-stability EE 11 integrations promoted toward default.
