This change log documents the significant updates and resolutions implemented from version 0.3.0-ballot to 1.0.0-ballot.

Changes in this version

  • In the AU Core Data for Interoperability page, to align to the published AUCDI Release 1 (R1):
    • added AUCDI element mapping Date/Time of Measurement and Date/Time of Observation, and added future consideration note for Last Updated
