The Change Tracking feature allows Teamwork users to follow any modifications made in the project by fellow teammates. This functionality was introduced in Archicad 24 and is only available with BIMcloud. (It is not a part of the BIMcloud Basic feature-set).
You can create a Subscription to a Set of Elements (filtered by Criteria, Selected Elements or Project Information). See the example below where a Subscription was created to track changes to a Stair:
