1.19.0 (June 12, 2024)

BREAKING CHANGES:

• telemetry: State store usage metrics with a double consul element in the metric name have been removed. Please use the same metric without the second consul instead. As an example instead of consul.consul.state.config_entries use consul.state.config_entries [GH-20674]

SECURITY:

• Upgrade to support Envoy 1.27.5 and 1.28.3. This resolves CVE CVE-2024-32475 (auto_sni). [GH-21017]
• Upgrade to support k8s.io/apimachinery v0.18.7 or higher. This resolves CVE CVE-2020-8559. [GH-21017]

FEATURES:

• dns: queries now default to a refactored DNS server that is v1 and v2 Catalog compatible. Use v1dns in the experiments agent config to disable. The legacy server will be removed in a future release of Consul. See the Consul 1.19.x Release Notes for removed DNS features. [GH-20715]
• gateways: api-gateway can leverage listener TLS certificates available on the gateway's local filesystem by specifying the public certificate and private key path in the new file-system-certificate configuration entry [GH-20873]

IMPROVEMENTS:

• dns: new version was not supporting partition or namespace being set to 'default' in CE version. [GH-21230]
• mesh: update supported envoy version 1.29.4 in addition to 1.28.3, 1.27.5, 1.26.8. [GH-21142]
• upgrade go version to v1.22.4. [GH-21265]
• Upgrade github.com/envoyproxy/go-control-plane to 0.12.0. [GH-20973]
• dns: DNS-over-grpc when using consul-dataplane now accepts partition, namespace, token as metadata to default those query parameters. consul-dataplane v1.5+ will send this information automatically. [GH-20899]
• snapshot: Add consul snapshot decode CLI command to output a JSON object stream of all the snapshots data. [GH-20824]
• telemetry: Add telemetry.disable_per_tenancy_usage_metrics in agent configuration to disable setting tenancy labels on usage metrics. This significantly decreases CPU utilization in clusters with many admin partitions or namespaces.
• telemetry: Improved the performance usage metrics emission by not outputting redundant metrics. [GH-20674]

DEPRECATIONS:

• snapshot agent: (Enterprise only) Top level single snapshot destinations local_storage, aws_storage, azure_blob_storage, and google_storage in snapshot agent configuration files are now deprecated. Use the backup_destinations config object instead.

BUG FIXES:

• docs: Consul DNS Forwarding configuration for OpenShift update for Resolve Consul DNS Requests in Kubernetes [GH-20439]
• hcp: fix error logs when failing to push metrics [GH-20514]
• streaming: Handle ACL errors consistently when blocking query timeout is reached. [GH-20876]
