+1. **Addition of *AzureSpeechTranscriber*:**
+ You can now configure assistants to use Azure's speech transcription service by setting 
+`AzureSpeechTranscriber.provider` to `azure`. Additionally, you will receive azure transcriber errors like `pipeline-error-azure-speech-transcriber-failed` in `Call.endReason`, `ServerMessageEndOfCallReport.endReason`, and `ServerMessageStatusUpdate.endReason`. 
+
+2. **Combined `serverUrl` and  `serverUrlSecret`  into `server` Property**:
+ The `serverUrl` and `serverUrlSecret` properties have been replaced by a new `server` property in multiple schemas. This lets you configure webhook endpoints using the `server` object, allowing for more detailed and flexible setup, including URL and authentication, in a single place. These schemas include:
+- ByoPhoneNumber
+- BuyPhoneNumberDTO
+- CreateByoPhoneNumberDTO
+- CreateOrgDTO
+- CreateTwilioPhoneNumberDTO
+- CreateVapiPhoneNumberDTO
+- CreateVonagePhoneNumberDTO
+- ImportTwilioPhoneNumberDTO
+- ImportVonagePhoneNumberDTO
+- Org
+- OrgWithOrgUser
+- TwilioPhoneNumber
+- UpdateOrgDTO
+- UpdatePhoneNumberDTO
+- VapiPhoneNumber
+- VonagePhoneNumber
+
+3. **Introduction of New OpenAI Models**:
+You can now use `o1-preview`, `o1-preview-2024-09-12`, `o1-mini`, and `o1-mini-2024-09-12`. in `OpenAIModel.model`.
+
+4. **Introduction of *'sonic' Voice Models* in Voice Schemas:**
+ You can now use `sonic` and `sonic-preview` models in `CartesiaVoice.model` and `FallbackCartesiaVoice.model` configurations.
+
+5. **Removal of Deprecated *GroqModel* Models:**
+ The models `llama3-groq-8b-8192-tool-use-preview` and `llama3-groq-70b-8192-tool-use-preview` have been removed from `GroqModel.model`. You should switch to supported models to avoid any disruptions.
