 ### BEHAVIOR CHANGE
 
 Automatic token refresh is now configured using `.UseBackgroundTokenRefresh()` or `.UseOnDemandTokenRefresh()` when building the SDK object.
 The default configuration can be overridden via environment variables or by passing an options object as a parameter.
 The old builder methods are still available but deprecated. Using them will apply the default configuration for automatic token refresh.
 
-In addition, the extended login methods are deprecated. Any values set for `autoRefresh` or `refreshThreshold` will be ignored in favor of the new configuration values.
