# Release v0.7.4 > Release Date: Mar 17, 2022 #### New Features - Adds support for using a websocket connection as an alternative to webhooks. - [config](/docs/webhooks/config/) verb was added to allow session-level speech defaults to be manipulated during a call. - [gather](/docs/webhooks/gather) and [transcribe](/docs/webhooks/transcribe) now support voice activity detection, which can be used to delay the connection to a speech service until speech is detected. This can reduce the costs of using some speech providers since the connection to the provider is delayed until speech is actually detected. - Allow target-level headers on [dial](/docs/webhooks/dial) verb. - Add support for handling incoming SIP REFER while in a [dial](/docs/webhooks/dial) verb. - Additional parameters were added to the [gather](/docs/webhooks/gather) verb. - Add rate limiting of API requests. - Add support for redis user/password authentication. #### Bug fixes - Rest outdial sometimes failed due to req.srf not properly set. - When running on kubernetes, use sbc-sip service rather than pinging sbcs. - Use registered contact as uri when sending to user. - Disable DNS caching on Kubernetes when routing calls from SBC to feature servers to prevent intermittent failures when service endpoints change. #### Availability - Available now on AWS Marketplace - Deploy to Kubernetes using [this Helm chart](https://github.com/jambonz/helm-charts) **Questions?** Contact us at support@jambonz.org
