</Warning>

<Warning>
  Starting with Cognigy.AI release 4.68.0, Weaviate v1.19.0 will no longer be supported. If you have a Cognigy on-premises installation and are utilizing the [Knowledge AI features](https://docs.cognigy.com/ai/empower/knowledge-ai/overview/), upgrade Weaviate to v1.22.5.

### Cognigy Voice Gateway

**Released** January 9, 2024

#### Bug Fixes

* Fixed the issue where the selected language did not promptly map to the corresponding voices

### Infrastructure

#### Cognigy Voice Gateway

* Updated the `helm.sh/hook` annotations for the following `Secret` resources to `"helm.sh/hook": "pre-install,pre-upgrade"`:
  * voice-gateway-call-recording-credentials
  * voice-gateway-drachtio-secret
  * voice-gateway-jwt
  * voice-gateway-mysql-password
* Remove unused `replicaCount` from `spec.Values` for:
  * rtpEngine
  * rtpEngineSidecar
  * sbcSipSidecar
* With the release of 4.65.0, we introduced `StatefulSets` for `sbc-sip` and `sbc-rtp`. We recommend enabling `StatefulMode` as it improves the load balancing of traffic between the replicas.
  * The required changes in values.yaml:
    * `spec.Values.sbc.sip.useStatefulSet: true`
    * `spec.Values.sbc.rtp.useStatefulSet: true`
  ```yaml theme={null}
  sbc:
    sip:      
      useStatefulSet: true
    rtp:      
      useStatefulSet: true
  ```
* With the release of 4.65.0, we introduced Redis High Availability. We recommend enabling `redisHa`:
  * The required changes in values.yaml:
  ```yaml theme={null}
  cognigyEnv:
    FEATURE_REDIS_SENTINEL_MODE_ENABLED: "true"
    REDIS_SENTINEL_MASTER_NAME: "mymaster"
    REDIS_SENTINEL_HOST: "redis-ha-headless"
    REDIS_SENTINEL_PORT: "26379"
    
  redisHa:
    enabled: true
  metrics:
    serviceMonitor:
      enabled: true
  ```
* With the release of 4.64.0, we disabled Grafana via a feature flag since we are using `cognigy-monitoring-stack`, which already includes Grafana. In the current release, we are removing all Grafana-related resources from the Helm charts:
  * Service: `grafana/service.yaml`
    * Deployment: `grafana/deployment.yaml`
    * ConfigMap: `grafana/config-map.yaml`
    * StorageClasses:
      * `templates/gcp/grafana/storage-class.yaml`
      * `templates/azure/grafana/storage-class.yaml`
      * `templates/aws/grafana/storage-class.yaml`

* [Cognigy.AI, Insights, and Agent Copilot](/ai/administer/installation/version-compatibility-matrix)
