+The variable name for the stored, URL parameter has been changed from `url` to `serviceUrl`. Note that `url` can still be compatibility passed into the constructor as an alias for `serviceUrl`. However, if you try to access the `url` property directly in your code, this is a breaking change.

 ### Breaking changes by service
 #### Assistant v1
