4.67 - Happy New Year ๐ŸŽ‰โ„๏ธ

Removal of text-davinci-003 by OpenAI

Due to the sunset of the text-davinci-003 model by OpenAI on January 4, 2024, this model will no longer be available in Cognigy.AI.

Weaviate Upgrade to v1.22.5

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, upgrade Weaviate to v1.22.5. For a smooth upgrade, refer to the guide.

Deprecation of Single Replica Redis

Starting from Cognigy.AI release v4.65, the Single Replica Redis setup is deprecated and replaced with Redis in High Availability (HA) Mode. For on-premises installations, before upgrading to Cognigy.AI v4.65, ensure that you migrate according to the Redis: Single Replica to Redis HA Migration.

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
        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:
      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
