From within our portal, you can validate against the current version of the standard version 3.2.1, up until the date that version 4.0 is implemented. After the update has been applied and version 4.0 is available, your reporting journey will be against version 4.0 of the standard. If you do have a valid Attestation of Compliance (AoC) for version 3.2.1 that you wish to upload, you can do so up until March 31st, 2024. After that date only version 4.0 will be accepted.
