Breaking changes
* removed `custom_fields.application_properties` field from the chat completion request (223); use new API to retrieve application properties instead:
- `await request.request_dial_application_properties()` to fetch application properties from the DIAL listing
- `request.unreliable_dial_application_properties` to get application properties supplied by Core in the request headers (keep in mind that excessively large headers may be removed in transit, thus, _unreliable_ qualification)
