 # Changelog
 
-## v4.0.0 Beta 4 (2022/11/26)
+## v4.0.0 Beta 5 (2022/12/01)
 ### Breaking Changes
 - `alt_auth_flow` has been removed as a valid configuration parameter. This has been deprecated for 6 months. See [here](https://rogerselwyn.github.io/O365-HomeAssistant/authentication.html) for details of how to configure `alt_auth_method` to meet your needs.
 - `calendar_id` is no longer supported as a parameter in service calls. `entity_id` should be used instead. Overall the changes to service calls in this release improve validation and should make it clearer when calling the service as to what a problem might be if one occurs. It also significantly simplifies the code which will benefit future changes.
