# Bundle Manager Subsystem Changelog
## cl.bundlemanager.1 Deleted the atomicService Tag from the app.json File
The **atomicService** tag is deleted from the **app.json** file.
**Change Impact**
If this tag is used, an error is reported during compilation on DevEco Studio.
**Adaptation Guide**
Delete the **atomicService** tag from your code.
## cl.bundlemanager.2 Added the bundleType Tag to the app.json File
The **bundleType** tag is added to the **app.json** file.
**Change Impact**
For an existing ability with [installationFree](../../../application-dev/quick-start/module-configuration-file.md) set to **true**, **bundleType** must be set to **atomicService** in the **app.json** file. Otherwise, the packaging fails.
**Adaptation Guide**
Add the [bundleType](../../../application-dev/quick-start/app-configuration-file.md) tag. This tag can be left blank. The default value is **app**. The setting of this tag and the [installationFree](../../../application-dev/quick-start/module-configuration-file.md) field in the **module.json** file must meet the following rules:
- If **bundleType** is **app**, **installationFree** must be set to **false**.
- If **bundleType** is **atomicService**, **installationFree** must be set to **true**.
