# Ability Subsystem ChangeLog

## cl.ability.1 System API Usage Rule Change

System application verification is not performed for system APIs provided by the ability when they are called. The APIs can be used by a third-party application using the full SDK, which brings security risks. Therefore, application identity verification is added to OpenHarmony 4.0.2.1 and later versions.

**Change Impacts**

System APIs are available to only system applications. When a third-party application tries to use a system API, the **202** error will be returned via either an exception or asynchronous callback.

**Key API/Component Changes**

Below are the system APIs.
