Delivered under the newly-formed MicroProfile Working Group, the much anticipated release of MicroProfile 4.0 was made available to the Java community. Features include alignment with Jakarta EE 8 and updates to all 12 core APIs. The standalone APIs, however, remain unchanged at this time.
The CDI, JAX-RS, JSON-P and JSON-B APIs, originally based on their equivalent JSRs, are now based on their equivalent Jakarta EE 8 specifications, namely Jakarta Contexts and Dependency Injection 2.0, Jakarta RESTful Web Services 2.1, Jakarta JSON Processing 1.1 and Jakarta JSON Binding 1.0.
