+1. **New Call Transfer Modes Added**: you can now wait for an operator to speak first before providing a transfer message or summary when transferring calls to a new destination with `TransferPlan`. Configure this through *transferPlan.mode=`'warm-transfer-wait-for-operator-to-speak-first-and-then-say-message'`* or `*transferPlan.mode=`'warm-transfer-wait-for-operator-to-speak-first-and-then-say-summary'`* inside the request body of `POST /assistant` or `PATCH /assistant`. 
 
-1. **Purchase Reserved Concurrency and Scale Infinitely**: You can now reserve more concurrent calls with Vapi and scale infinitely by switching to our new top up payment system on the [billing page](https://dashboard.vapi.ai/org/billing). To migrate, click "Switch to Credit Based Billing" and make a payment. Advantages include:
+2. **Unified Server Configuration in Assistants**: You can now use the `server` property in `Assistant.server`, `AssistantOverrides.server`, and when creating or updating assistants to specify webhook settings, including URL, secret, custom headers, and timeout. This replaces the old `serverUrl` and `serverUrlSecret` properties of `Assistant`.
 
-  - **Support More Users Without Limits**: You don't need to worry about getting throttled or staying under usage limits on the conversations you can have with Vapi.
-  - **Predictable Budgets**: You know exactly how much you will spend on Vapi each month, and you can top up at any time as your needs grow.
-  - **Select Add-Ons You Need**: The credit based billing page allows you to select HIPAA compliance, dedicated Slack support, and the maximum number of concurrent calls you expect.
+  <Warning>Include custom headers in your webhook requests by using the `headers` property within the `server` object when creating or updating assistants.</Warning>
+
+3. **Configure PlayHT Voice Engines**: You can now configure which PlayHT voice `model` generates voices for your application between `PlayHT2.0`, `PlayHT2.0-turbo`, and `Play3.0-mini`.
 
-<Warning>This will require human input to login and migrate your account. You will not be able to revert back to the old billing system.</Warning>
