1. Integration of Smallest AI Voices: Assistants can now utilize voices from Smallest AI by setting the voice provider to Assistant.voice[provider="smallest-ai"], allowing selection from a variety of 25 preset voices and customization of voice attributes.

2. Support for DeepSeek Language Models: Developers can now configure assistants to use DeepSeek LLMs by setting the Assistant.model[provider="deep-seek"] and Assistant.model[model="deepseek-chat"]. You can also specify custom credentials by passing the following payload:

{
  "credentials": [
    {
      "provider": "deep-seek",
      "apiKey": "YOUR_API_KEY",
      "name": "YOUR_CREDENTIAL_NAME"
    }
  ],
  "model": {
    "provider": "deep-seek",
    "model": "deepseek-chat"
  }
}

3. Additional Call Ended Reasons for DeepSeek and Cerebras: New Call.endedReason have been added to handle specific DeepSeek and Cerebras call termination scenarios, allowing developers to better manage error handling.

4. New API Endpoint to Delete Logs: A new DELETE /logs endpoint has been added, enabling developers to programmatically delete logs and manage log data.

5. Enhanced Call Transfer Options with SIP Verb: You can now specify a sipVerb when defining a TransferPlan with Assistant.model.tools[type=transferCall].destinations[type=sip].transferPlan giving you the ability to specify the SIP verb (refer or bye) used during call transfers for greater control over call flow.

6. Azure Credentials and Blob Storage Support: You can now configure Azure credentials with support for AzureCredential.service[service=blob_storage] service and use AzureBlobStorageBucketPlan withAzureCredential.bucketPlan, enabling you to store call artifacts directly in Azure Blob Storage.
