There are no functional differences between the current version of the OA3Tool that was released in Windows ADK 10.1.25398.1 (September 2023) and the one that will be released in April 2024. They will have different build numbers, but all other features and functionality will remain the same. Therefore, partners can begin testing and fully adopting the currently available OA3Tool build 10.0.25398.1 and still be counted as compliant with the mandatory release coming in April 2024.
