Jakarta EE has transitioned from Java EE to an open governance structure at the Eclipse Foundation. Key points: - Java EE specifications and reference implementations were contributed to Eclipse Foundation projects in 2018. - Jakarta EE 8 was released in September 2019, compatible with Java EE 8. - Governance includes the Jakarta EE Steering Committee and Specification Committee. - Future directions include embracing modules, preferring soft dependencies, and focusing on testing. - The community is invited to get involved to help define the future of Jakarta EE 9.
