Spec Lead Guide: Maintenance Release (MREL)
Return to the top of the Spec Lead Guide
A Maintenance Release is the updated version of the Final Release incoporating the changes approved from a Maintenance Review. Usually a Maintenance Release is posted automatically by the PMO after a successful Maintenance Review. However, in the case of changes being made during the Maintenance Review and/or items from the change log being deferred by an Item Exception Ballot from the EC, you may find the need to submit a new set of Maintenance Release materials to replace what was submitted for your Maintenance Review. "DEFERRED" items may not be placed in a Maintenance Release but must go into a new JSR. The Maintenance Release process is like the Final Release Process.
To post a Maintenance Release, you need to submit all of the following to the PMO (, specifying the JSR number and "Maintenance Release" in the subject line:
  1. The Spec, in pdf or zip format (please note that Javadoc files must be zipped).
  2. The version number for your spec, full legal name and address for your company/organization. This will be used to create the Final Release license. As an alternative, you may provide your own, but providing your own license can delay the posting due to necessary legal review.

  4. The location where the Reference Implementation is posted for Maintenance Release.
  5. The location where the Technology Compatibility Kit is posted for Maintenance Release.
  6. The process by which qualified individuals and educational or not for profit organizations can access the TCK at no cost.
