On 17 April 2014, the AEMC published its final rule determination and final rule on the AER Authorisation of Software Changes by AEMO rule change request.

The final more preferable rule removes the NER requirement on the AER to approve changes made by AEMO to the software required for the operation of the market as requested, but it does not insert a new requirement for AEMO to make software changes in accordance with its IT Change Management Procedures Manual.
