The OpenLiberty project has released OpenLiberty 26.0.0.5, with official support for Jakarta EE 11 across Core, Web, and Platform profiles, and support for Spring Boot 4 JAR files as opposed to WAR files.
Jakarta EE 11 support is increasing across the industry; it's adding Jakarta Data 1.0, a standardized repository-style API for data access. Jakarta Data is one of the first new updates to the specification for Jakarta EE, as opposed to renaming javax packaging to jakarta packaging.
The version number is date-based, even though it looks vaguely semver - it just means that this is the May 2026 release. If you asked me what the two middle numbers meant, I could not tell you; I cannot find references to any releases that change the ".0.0." in the version numbers, although my search was casual. With that said, though:
Changing the EE spec from javax to jakarta is a painful transition, comparable to the Python 2 -> 3 transition, but as projects and libraries survive the update, the ecosystem is showing a lot of progress lately.
