# Ability Framework Changelog

## cl.ability.1 Ability Assistant No Longer Supports Debugging of Applications in Release Mode

**Access Level**

Public API

**Reason for Change**

The Ability Assistant tool is the bottom-layer dependency for debugging capabilities of DevEco Studio. Normally, DevEco Studio restricts debugging of applications in release mode. However, there is a risk of bypassing DevEco Studio and directly using the debugging commands of Ability Assistant for debugging. Therefore, this behavior must be fundamentally restricted.

**Change Impact**

This change is a non-compatible change.

Before change:
There is a risk of bypassing DevEco Studio and directly running the commands of Ability Assistant to debug applications in release mode.

After change:
The Ability Assistant tool does not support debugging of applications in release mode.

## cl.ability.2. It Is Forbidden to Start an ExtensionAbility using wantAgent

**Access Level**

Public API

**Reason for Change**

After a user touches the notification on the home screen, the ExtensionAbility starts. When the user exits the application, the ExtensionAbility process does not exit, affecting power consumption.

**Change Impact**

This change is a non-compatible change.

Before change:
A third-party application creates a wantAgent for an ExtensionAbility and sends a notification containing the wantAgent. When users can touch the notification on the home screen, the ExtensionAbility starts.

After change:
A third-party application creates a wantAgent for an ExtensionAbility and sends a notification containing the wantAgent. When users touch the notification on the home screen, the ExtensionAbility does not start.
