1.17.0-rc1 (October 11, 2023)

BREAKING CHANGES:

• api: RaftLeaderTransfer now requires an id string. An empty string can be specified to keep the old behavior. [GH-17107]
• audit-logging: (Enterprise only) allowing timestamp based filename only on rotation. initially the filename will be just file.json [GH-18668]

FEATURE PREVIEW: Catalog v2

This release provides the ability to preview Consul's v2 Catalog and Resource API if enabled. The new model supports
multi-port application deployments with only a single Envoy proxy. Note that the v1 and v2 catalogs are not cross
compatible, and not all Consul features are available within this v2 feature preview. See the v2 Catalog and Resource
API documentation for more information. The v2 Catalog and
Resources API should be considered a feature preview within this release and should not be used in production
environments.

Limitations

• The v2 catalog API feature preview does not support connections with client agents. As a result, it is only available for Kubernetes deployments, which use Consul dataplanes instead of client agents.
• The v1 and v2 catalog APIs cannot run concurrently.
• The Consul UI does not support multi-port services or the v2 catalog API in this release.
• HCP Consul does not support multi-port services or the v2 catalog API in this release.
• The v2 API only supports transparent proxy mode where services that have permissions to connect to each other can use
  Kube DNS to connect.

Known Issues

• When using the v2 API with transparent proxy, Kubernetes pods cannot use L7 liveness, readiness, or startup probes.
