# Upgrading from 9.1.0 to 9.2.0 (web)

- A new sessionData parameter is added to the MethodUIFactory.createMethodUI() function. See [Client API Docs](/dpoa/docs/s3suite94-web-client-api-docs-1) for MethodUIFactory interface for more details. If your application has a custom implementation of the MethodUIFactory interface, update the createMethodUI() function implementation and:
  - Add the new sessionData parameter.
  - Pass the sessionData parameter when calling the createMethodUI() function of the default factory.
  - If your implementation creates an instance of ExternalAuthMethodUI, OOBMethodUI or OtpMethodUI classes, then pass the sessionData parameter as the last argument to any of these three constructors. See [Client API Docs](/dpoa/docs/s3suite94-web-client-api-docs-1) for ExternalAuthMethodUI, OOBMethodUI or OtpMethodUI for more details.
- The onGetCredential() function in the interface IExternalAuthLiveData has a new, required additionalErrorInfo parameter. If your application implements the interface IExternalAuthLiveData, add that parameter to your implementation of onGetCredential(). See [Client API Docs](/dpoa/docs/s3suite94-web-client-api-docs-1) for details on how to use the parameter additionalErrorInfo.
- If you replaced the Try Passwordless UI in the previous App SDK, then you defined a class that implements the ITryFidoUiFactory interface. This interface now requires an additional method createTryHybridUi(). See SampleTryFidoUiFactory in the file js/samples.js for an example implementation in Tutorial App. See [Client API Docs](/dpoa/docs/s3suite94-web-client-api-docs-1) for ITryFidoUiFactory interface for more details.
