v1.19.0 (Enterprise)

1.19.0 (June 12, 2024)

This release is created to share the Consul Enterprise changelog and notify consumers of availability. The attached source and assets do not include Consul Enterprise code and should not be used in place of official Docker images or binaries.

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]
