        However there is a problem with the hyperlink in
            the email.  Clicking the link will take you to the 2.3
            page.  You have to copy and paste the visible address (http://www.eclipse.org/eclipselink/releases/2.4.php).

        Hey all,
          
          I am very excited to announce that EclipseLink 2.4.0 is now
          available for download
          http://www.eclipse.org/eclipselink/releases/2.4.php.
          
          Highlights of this release include:....
          
          RESTFul Persistence
          Java Persistence units can now be exposed over REST using
          either JSON or XML media.
          
          
          Tenant Isolation - Table per tenant
          Developers can design and deploy applications where their
          persistent entities are stored in separate tables per tenant.
          
          NoSQL
          This release introduces EclipseLink's NoSQL support for
          MongoDB and Oracle NoSQL.    
          
          
          JSON
          EclipseLink MOXy can now be used for the marshaling and
          unmarshaling of JSON object.  This is core infrastructure to
          the JPA-RS feature.
