# Changelog of NFC JS APIs in the Communication Subsystem
Compared with OpenHarmony 3.2 Beta4, OpenHarmony 3.2.10.2(Mr) has the following changes in NFC APIs:
## 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.
**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.
