+## What's New
+
+### Compliance & Security Enhancements
+- **New [CompliancePlan](https://api.vapi.ai/api#:~:text=CompliancePlan) Consolidates HIPAA and PCI Compliance Settings**: You should now enable HIPAA and PCI compliance settings with `Assistant.compliancePlan.hipaaEnabled` and `Assistant.compliancePlan.pciEnabled` which both default to `false` (replacing the old HIPAA and PCI flags on `Assistant` and `AssistantOverrides`).
+
+- **Phone Number Status Tracking**: You can now view your phone number `status` with `GET /phone-number/{id}` for all phone number types ([Bring Your Own Number](https://api.vapi.ai/api#:~:text=ByoPhoneNumber), [Vapi](https://api.vapi.ai/api#:~:text=VapiPhoneNumber), [Twilio](https://api.vapi.ai/api#:~:text=TwilioPhoneNumber), [Vonage](https://api.vapi.ai/api#:~:text=VonagePhoneNumber)) for better monitoring.
+
+### Advanced Call Control
+
+- **Assistant Hooks System**: You can now use [`AssistantHooks`](https://api.vapi.ai/api#:~:text=AssistantHooks) to support `call.ending` events with customizable filters and actions
+  - Enable transfer actions through [`TransferAssistantHookAction`](https://api.vapi.ai/api#:~:text=TransferAssistantHookAction). For example:
+```javascript
+{
+  "hooks": [{
+    "on": "call.ending",
+    "do": [{
+      "type": "transfer",
+      "destination": {
+        // Your transfer configuration
+      }
+    }]
+  }]
+}
+```
+
+  - Conditionally execute hooks with `Assistant.hooks.filter`. For example, trigger different hooks for call completed, system errors, or customer hangup / transfer:
+
+```json
+{
+  "assistant": {
+    "hooks": [
+      {
+        "url": "https://api.example.com/success-handler",
+        "filter": {
+          "type": "oneOf",
+          "key": "call.endedReason",
+          "oneOf": ["COMPLETED"]
+        }
+      },
+      {
+        "url": "https://api.example.com/error-handler",
+        "filter": {
+          "type": "oneOf",
+          "key": "call.endedReason",
+          "oneOf": ["ERROR", "SYSTEM_ERROR"]
+        }
+      },
+      {
+        "url": "https://api.example.com/customer-actions",
+        "filter": {
+          "type": "oneOf",
+          "key": "call.endedReason",
+          "oneOf": ["CUSTOMER_HANGUP", "CUSTOMER_TRANSFER_REQUESTED"]
+        }
+      }
+    ]
+  }
+}
+```
+
+### Model & Voice Updates
+
+- **New Models Added**: You can now use new models inside `Assistant.model[provider="google", "openai", "xai"]` and `Assistant.fallbackModels[provider="google", "openai", "xai"]`

+
+### API Improvements
+
+- **Workflow Updates**: You can now send a [`workflow.node.started`](https://api.vapi.ai/api#:~:text=ClientMessageWorkflowNodeStarted) message to track the start of a workflow node for better call flow tracking
+
+- **Analytics Enhancement**: Added subscription table and concurrency columns in [POST /analytics](https://api.vapi.ai/api#/Analytics/AnalyticsController_query) for richer queries about your subscriptions and concurrent calls.
+
