Open Liberty 26.0.0.5 introduces official support for Jakarta EE 11 (Core Profile, Web Profile, and Platform), Spring Boot 4.0 applications, and updated TLS/SSL cipher handling. Jakarta EE 11 is the first release to add a new specification since Java EE 8 in 2017 and removes all optional specifications from the Platform. The new springBoot-4.0 feature supports both JAR and WAR deployment formats and requires Java 17+ with Jakarta EE 11 features. TLS/SSL configuration is simplified by deprecating the securityLevel attribute in favor of a more flexible enabledCiphers filter syntax using +/- wildcards. A CVE fix for identity spoofing (CVSS 7.5) is also included.
