# Changelog of NFC JS APIs in the Communication Subsystem

## cl.nfc.1 API Change
Deprecated some NFC JS APIs in API versions 6 to 8 because the APIs cannot throw error codes, and added new APIs in API version 9 instead.

You need to adapt your application based on the following information.

 **Change Impact**

The deprecated JS APIs in API versions 6 to 8 are affected. Your application needs to adapt new APIs so that it can properly implement functions in the SDK environment of the new version.
