On 14 Nobember 2021, Webtools launched a new Synchronisation API version in the Asset Manager.
For your reference, please see the previous communication on this matter: https://ec.europa.eu/newsroom/cem/newsletter-archives/34183.
As mentioned in the last paragraph it includes backwards-compatibility, allowing workflows to be adapted accordingly to the new version.

We would hereby like to inform you that this backwards-compatibility will be removed on 30 June 2022 and all processes need to be aligned with the new Synchronisation API Version.

If you have questions please do not hesitate and contact us.
