I am happy to announce, that the first non-snapshot development build of JAX-RS 2.1 API (2.1-m01) has been released. It is already accessible from mave.java.net repository <https://maven.java.net/content/repositories/releases/javax/ws/rs/javax.ws.rs-api/2.1-m01/>. Please allow a few hours before trying to download the bits from the central maven repository.
